Ubuntu :: Kernel Bug - Multiple Mail Clients Crashing 10.04?

Aug 18, 2010

Over the past week or so, I've posted a few message about what looked like general stability problems in lucid, then problems specifically with Thunderbird.

Today I found it isn't just Thunderbird. I tried Claws Mail and Kmail, and all of them exhibit the same symptoms as Thunderbird:

- The app randomly hangs, crashes or stops connecting to the mail server.

- Quitting the app randomly takes down other applications. (Uh-oh -- modern OSs are supposed to prevent one application from corrupting another.)

- Once the problems start, any application is likely to have stability problems -- e.g., this morning, when Kmail started buggering up, I launched the software center to uninstall it and the window never appeared. A box showed up in the window panel at the bottom of the screen at first, but when it was time to draw the window, kaboom.

(I'm currently not using Evolution because of issues with syncing message deletion back to the server. Plus, at least once, Evolution lost its connection to the mail server. I don't remember serious instability with it, but I wasn't looking for the instability either. It might well be just as bad as the others.)

So, we have an issue triggered by multiple applications, and the issue is not limited to one unstable process on the machine (one unstable process makes other processes unstable). That smells like a kernel bug.

I'm wondering if anyone else has seen anything like this? I'm using the amd64 version on a MSI A6200, Intel Core i3 processor. I'll have to doublecheck the kernel version. When I installed the OS, it was (something-something).21 and now (after the first round of automatic system updates) it's .24 - "something-something" is whatever the standard kernel is when you download the amd64 CDROM image.

As long as I'm not running a mail client (apparently, any mail client), the system is stable. So it looks very much like there is something that mail clients do, which other applications tend not to do, which is broken.

Server :: E-mail Clients Know Whether Or Not An E-mail Is Part Of A Thread?

Jul 5, 2011

How do e-mail clients know whether or not an e-mail is part of a thread? (For example, Thunderbird can fold e-mails into threads.) Do they just guess based on the Subject line, or do they know for certain based on an e-mail field? I was planning to tackle some more advanced filter programming on my Postfix server.

Server :: Configure Postfix To Relay Mail To Multiple Internal Mail Servers With Different Domains?

Aug 6, 2010

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.

I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.

Ubuntu :: Can't Set Alternative Mail Clients In Preferred Apps / Fix It?

Apr 28, 2011

I'm trying to set Desktop-Webmail to be the preferred Mail Client in Preferred Applications in Natty, but Evolution is the only selectable option.

Purging Desktop-Webmail didn't help, nor did trying other such apps like gnome-gmail.

Any ideas on how the list of Mail Clients can be set?

Ubuntu :: Script Through Multiple SSH Clients?

Sep 22, 2010

How do I start a script on an ssh server which then starts another script on another ssh server?

Long Explaination I would love to be able to connect to a server with ssh and start a script there which sends a magic packet to my client and waits till it answers the ping. This script is already working, without any problems. After the client started I would love to be able to ssh into the freshly booted client and start another script that starts a Virtual Machine and waits for the ping to answer. The script is working, but how do I start the second script directly from the first one? Best thing would be if I wouldn't have to put in the ssh password again (as it is the same user and the same password).

Software :: OpenVpn Multiple Clients Gets The Same Client Ip

Mar 9, 2010

I'm using openvpn-2.0.9 with gui-1.0.3 which is set up on windows xp machines(for server and clients) when i set up the server and one client it connects well and i can work without a problem. but when the second client connects it gets the same ip address of the client1, so that both clients can't work at once.

my server and client config files are as follows.

server-configuration file

client1-configuration file

client2-configuration file

I've tried by changing many settings such as server-bridge and all but couldn't find a solution for the problem.

By the way when connected server gets 10.8.0.1/30 and every clients get same ip as 10.8.0.6/30

Debian Multimedia :: Evolution Crashing On Mail Send

Aug 5, 2015

Evolution keeps crashing everytime I send mail. I am also constantly asked for my keyring or email passwords. I checked the log and found this error message.

"CRITICAL **: mail_session_refresh_cb: assertion 'service != NULL' failed"

This message was in a bug report from 2013 that seems to be closed.: https://bugs.debian.org/cgi-bin/bugrepo ... bug=730256

My system : Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt11-1+deb8u2 (2015-07-17)

synaptic package manager says my evolution and keyring are the latest.

I usually run Xfce if that means anything.

Fedora Servers :: Configure Evolution-mail Clients Through SQUID Proxy?

Jul 27, 2011

I have configured router(192.168.1.2) to serve only one machine with IP - '192.168.1.6' and set up SQUID proxy on '192.168.1.6'. I have defined some rules(ACL) regarding connections to internet on SQUID proxy.

I changed the Gateway of rest of machine (192.168.1.60 - 192.168.1.69) from '192.168.1.2' to '192.168.1.6'.

The policies which I defined in SQUID is working properly but 'Linux Evolution mail' client is not fetching mails.

Is I have to do any other settings on 'Linux System' or 'Evolution mail client'.

Server :: Sendmail SMTP Send Doesn't Work With OS X 10.6 Mail.app Clients

Aug 3, 2010

I've been having this problem since 10.6 released, but have until now been successful with the "just use Thunderbird" response. My sendmail server hasn't been changed, but as clients upgrade from OSX 10.5 to 10.6 suddenly mail.app will no longer connects to send SMTP messages through the server. (IMAP connections to the same server using the same user/pass combinations work perfectly) When I look at the logs, things basically stop right after the STARTTLS command.

Google indicates alot of people are having similar problems, but I'm not seeing any solutions. Do any of you administrate sendmail servers where some of your clients are using Apple's Mail.app on Snow Leopard, and if so what settings are you using? At this point, I'm happy to make changes to the server to accommodate Apple's issue, I have too many Mac users connecting to my server. I just can't figure out what to change. I've enabled virtually every possible login authentication combination, and none of them work.

Networking :: Xinetd To Fork New Instances Of Foo So Multiple Clients Can Connect To It

Aug 3, 2010

Suppose I have a server, foo, that runs on port 5555. I can make one connection to it at a time on that port. I want xinetd to fork new instances of foo so multiple clients can connect to it.

Here's a configuration entry:

1) How does xinetd fork a new instance of foo when a previous instance is already listening on port 5555? Wouldn't the new process fail to launch because port 5555 is already in use by the previous process?

2) Suppose five clients connect simultaneously, and xinetd forks five instances of foo. When the clients disconnect, does xinetd leave all five instances running?

CentOS 5 Networking :: OpenVPN Multiple Servers With Clients Access

what is the best way here? I have like 5 servers, and I want my clients to access each of them, so in case 1 server is down, they can access remaining servers. Also, it will work like user1 chooses the server number and is connecting to a central database, then reply is OK, and he can connect to the server number he wished.

Fedora :: Kernel Package Keeps Crashing ?

Nov 22, 2009

I'm using Fedora 12 64 bit, with XFCE

It happens that many times I get this message notification: " A crash in package kernel has been detected "

When I open the Automatic Bug Report Tool, I get that The Linux kernel crashed and Crash Rate says 78 times!

So it's crashing all the time but otherwise the system is running good so far..

How can i debug this? Any log I could check?

I didn't see anything particular in /var/log/messages

CentOS 5 :: Install, Recurring Kernel Panics Crashing System?

Dec 27, 2009

Recently switched my home server from Gentoo to CentOS and have been getting kernel panics consistently since I made the server "live". The machine was built with all new hardware. I'll post relevant configuration info and picture of the kernel panic below. So far all kernel panics have been with kernel "2.6.18-164.9.1.el5.centos.plus", right now I am testing with the kernel listed below to see if it does the same thing (2.6.18-164.9.1.el5).

justin@empire justin $ uname -rmi
2.6.18-164.9.1.el5 x86_64 x86_64
justin@empire justin $ rpm -qa |grep kernel |sort
kernel-2.6.18-164.6.1.el5
kernel-2.6.18-164.6.1.el5.centos.plus
kernel-2.6.18-164.9.1.el5

Ubuntu :: Mail Sync Between Multiple PCs With 8 Accounts

Jul 15, 2010

I've recently purchased a laptop so I've been focusing on getting my data synchronized between my laptop and PC. The problem is as follows, I have 8+ email accounts and I prefer to have them all in 1 single map tree instead of a separate tree for every one of them. This means IMAP is out of the question, so I've been thinking about a few things but I'm not too sure if there's anything out there for some of these things.

Option 1 - Unison Synchronization
Using Unison to synchronize the Thunderbird profiles, problem is Thunderbird can't be running on both machines

Option 2 - IMAP mail hub for all accounts
Somehow turn my server into a mail hub that gets email for all my accounts, and serve them through IMAP somehow, only problem that might be is that reply-to won't send a mail back with the same mail address people mailed to (Don't know that for sure).

Option 3 - POP3 mail hub
Same as option 2 but with a central POP3 hub that will keep all mails forever, should be doable.

Not viable option - Turn off mail deletion on server. This ain't viable because this will either cause some of the mail servers to clog up, especially if I were to only turn deletion on on 1 pc. So it seems the POP3 hub is best, and then just let that delete everything off of the remote servers, is this possible, I've tried setting up a mail daemon before but failed miserably (But will try again if it will make this possible).

Server :: Postfix: Sending Mail From Multiple Domains?

Jul 20, 2009

I'm running a server with two sites which both need to be able to send emails. Currently I have Postfix set up to send email via Google Apps. This works fine, but Google's servers ignore the From: address I specify and substitute the one I logged in with. Is there a way to make Postfix log into Google Apps with a different username based on what site the email is coming from? The server does not recieve any mail itself; Google recieves it and we have it set to forward it to the appropriate person's real email address. I'm only worried about sending mail.

(Postfix is not a requirement here, so if there's another mailer that can do this better, I'm open to ideas. However, sending email directly from the server isn't an option as it's a residential IP address and blocked by most of the big email providers.)

Ubuntu Servers :: Setup An Outbound SMTP Mail Server With & Using Multiple IP Addresses

Mar 15, 2010

This is the current setup that we have: We have approx 20 clients who pay us to send out a type of e-mail called an E-Blast to their customers. We currently are using 5 Microsoft Windows Virtual Servers to do this. The problem is that those machines are starting to break down. There are times that it will take Microsoft Windows approx 9-10 hours to complete 1 job. This is way too long. We want to move away from Microsoft Windows for this particular type of job as it seems there are more customers who are wanting to use this type of advertising.

It seems that using a Linux Server "Command Line or Shell" environment would be the best way to go as there is no GUI like Windows. Since there is just text...that is something that would/should process very, very quickly.

I am in the process of setting up a new SMTP outbound mail server. This is the current software & configuration (what is installed on this new machine):

All of the customer data (Names, E-Mail Addresses, etc that these e-mails are going to) are currently loaded in a Microsoft SQL Database.

My machine that I am using is plugged into the DMZ. I have 1 ip address for the 1 network card. I have also added/bound 4 more ip addresses to that network card.

I have configured Postfix for Multiple IP Addresses.

I can, from the command line, send successful test e-mails and receive them in my personal account.

As far as I know everything is setup correctly. I can and will post requested information so that it can be verified that everything is setup correctly.

Here are a couple of my questions:

Ensure that I have my Network / Interfaces file and my Postfix's Master.cf/Main.cf files setup correctly?

How can I setup this server to be an Outbound SMTP server and get it to use all 5 of the IP Addresses to send these e-mails quickly?

What can I use to check and ensure that this server is in fact sending out emails on all 5 IP

Addresses (I heard that there is a program named "Postal" that may help in determing this).

Ubuntu Servers :: Configure To Send And Receive Mail From Multiple Sub Domains Of Domain?

Jun 14, 2011

I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)

Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.

Server :: Unsure Of Exim Configuration - Accepts Mail From Users On Multiple Domains To Pass On To The Outside World

Dec 29, 2010

I'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):

* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )

*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )

Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?
