I reinstalled OpenSuSE because my hard drive filled up and i couldn't find what was taking up 30 GB of disk space. My SMTP and IMAP were working fine. Now, I can't telnet into smtp remotely and they no longer respond to my mail program.One last detail, I can send out mail to example, gmail.I can receive the mail at gmail but i can't send mail back because the imap and pop3 don't work.
View 3 Repliesi want to set up an email server both to receive and send emails. I also am on a dynamic ip scheme with my ISP. I do have a dynamic dns account with no-ip.org the Questions are:
-will somebody be able to send emails to me at the <user>@<dyndns_name>.no-ip.org email address?
-will I be able to send emails from the <user>@<dyndns_name>.no-ip.org email address?
I know i'll be able to login to accounts like gmail and yahoo and download emails from there.. but even that i don't know - even macroscopically how its done:
-is it the sendmail deamon that accepts the mail from <me>@gmail.com, <me>@yahoo.com, <me>@<dyndns_name>.no-ip.org?
-is it the sendmail deamon that does the sending of email (as well)?
-can it push emails that I want to send as <me>@gmail.com to the gmail smtp servers (and they in turn will push my email even further)?
-can it push emails from <me>@<dyndns_name>.no-ip.org to receipients?
and finally,
-WILL receiving pop/imap servers allow incoming email from my server? or due to the dynamic ip they'll assume I'm a spam server?
The server I'm running is virtually stock CentOS - it's running on a xen virtual host, started as CentOS 5.1 (32 bit) when that was fresh, it's at 5.5 now and updated nightly. All packages except postgresql and php are from CentOS and EPEL.
I'm running dovecot on it, and for long time, squirrelmail connecting via localhost was good enough. All external ports were firewalled by the CentOS firewall (just 25,80,443,custom ssh are currently open).
Now I need to allow an external imap client to connect.
I have generated ssl key and configured the dovecot configuration and it should be good to go, but gosh dangit, I can't remember how to open the port in the configuration.
I did it before when I set up ssh to run on a non standard port after I got sick of constant brute force attack on port 22, but I can't recall what I did and the various tutorials I find online all tell how to do it with the GUI tool, but I don't have any GUI stuff installed.

Is I'm pretty sure what I used to open up my custom > 1024 ssh port, but I can't remember how I used it to open that port and it doesn't seem intuitive. Also, do I need to use 993? I'd almost rather use something custom above 1024, as long as thunderbird supports it (don't care about any other mail client)
Finally, my smtp server is postfix and port 25 is already open (but not an open relay, I check it about every 3 months). For requests to send mail from a client, I would really like some authentication of some type - as in only relays for IP addresses that have recently successfully logged in the secure imap port.
Now, i want to change port smtp, not use 25

I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?
I want to know that by default do we need to configure SMTP and POP3/IMAP sever for sending and receiving mails in Linux server and client machines or we can directly send and receive mails without configuring these mail servers?
View 2 Replies View RelatedI was wondering if anyone has figured out how to access their Gmail files via IMAP on Konqueror? There is supposed to be an imap:// kio slave, but I can't get it to login to my Gmail. I tried imap://username@gmail.com but no luck. I also tried [URL].. since I think the username has to include the @gmail.com part. But still no access.
View 3 Replies View RelatedOpenSUSE version: 11.2 *and* 10.0 I am unable to send email. It appears I am being blocked by my ISP [URL]... A Wireshark trace shows ICMP type 3 Code 13 - "Administratively filtered". It's important to note that I don't know exactly when the problem started, because I seldom use my ISP email account, I use Yahoo web mail due to the "throwaway" nature if I get hit with spam. I only discovered the problem when testing the functionality of 11.2. I suspect the problem started several months ago: I restored openSUSE 10.0 and the problem exists there too. I wish I'd sent that last email via 10.0 before the upgrade.
The weird thing is that using Windows 2000 box I can get a successful connection using telnet (Telnet also fails on the openSUSE box.) It appears to me there is something in the Linux TCP stack that Teksavvy doesn't like. I am on dial up and I pointed this out to Teksavvy tech support, as I am probably the only person left on dialup and the reason no one else has reported the problem
Ok here's my setup :
SuSE 10.0 X86 32 acting as my internet gateway and firewall.
eth0 is my internal interface network 192.168.0.0/24 IP 192.168.0.254 dsl0 is my internet connection and is a single ip PtP connection to my ISP.
My internal network is masquaraded onto the external network.
I run an smtp server on my gateway box that I need to be accessable to both the internal and external networks.
However I want to prevent machines on the internal network from establishing connections to external smtp servers, but still alow them to connect to the smtp server on the gateway to send email.
NOTE I do not want to force attempts to connect to [URL] 25 to be re-directed to my internal server I just want to drop or reject the connection.
The firewall up until now has just been configured through YaST, but am not afraid to edit script files if needed
The reason for doing this it to prevent spambots from being able to send through my isp, I keep my own machines clean but sometimes get asked to disinfect machines for other people (family members etc), where I need to connect to the outside world to get updates/virus defs etc, but don't want them spamming from my network.
It seems I can't access smpt servers both from kmail and php. Kmail says
Code:
Sending failed:
smtp.gmail.com
The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.The following transport was used: ... I double checked my settings and they are correct. I can ping smtp.gmail.com. I can send emails using thunderbird on a windows box that is connected to the same network as I am.I also tried turning off the firewall through yast but no joy.
I'd like to use the mail command to send e-mails with some log files. Is there a way to configure the SMTP server from cli or to write the IP address into a file?
View 6 Replies View RelatedOn my opensuse 11.4 box (although I assume the version is irrelevant), I'm trying to figure out how to do something with the mail command. We have multiple smtp relay servers and sometimes I have to test to verify that mail is bouncing off of them successfully. On my laptop, in my main.cf file for postfix, I've got the relay server listed. But to test multiple servers, I have to change the main.cf, restart postfix, send message, and then repeat for each test.
I'm trying to figure out a way to specify the smtp relay on the command line. I've been playing with the -S option which is supposed to allow variables and one of the variables in the man page is 'smtp'. I've tried several different syntaxes but nothing seems to work.
The closest I've come is:
mail -S smtp 10.1.0.63 -s "test" user@email.com < main.cf
That syntax doesn't give me an error but it still routes the message off the smtp server listed in main.cf which is not 10.1.0.63.
It looks like the desktop amusements that used to work under KDE 3.5 no longer work in the current v4. I've installed xpeguins, but it does not seem to produce any output on the display. I have enabled desktop effects, but no penguins appear. Is there some setting needed for this to work?
I'm running SUSE 11.3/KDE 4.5.3.
When I had 11.0, I could ssh to my router without problems. When I switched to 11.2, I no longer could (three machines, one new, two upgraded). I have also tried from a VM 11.1. Putty in another VM also fails.

I have an Intel Mac that I recently added openSUSE 11.3 to to have a dual-boot system. This has been working fine for me for the last 5-6 months. Then on 1/18/2011 I shutdown my system and totally disconnected everything and moved it all out of my office, so new carpeting could be installed. After it was installed, I reconnected everything and confirmed that everything on my Mac side works just fine. Then I rebooted into Linux and everything worked until I tried to run Firefox to connect to the internet. I'm told every time that it could not connect to the server for whatever I tried to connect to. I AM NEW TO LINUX AND ANY KIND OF NETWORK/INTERNET PROBLEMS, SINCE I'M USED TO MAC WHERE EVERYTHING JUST WORKS. But, I did click on "computer" in the lower left-hand side of the menu bar at the bottom of the screen. This shows on the right-hand side under STATUS "Network: none" and then it states to click this to get it started or connected (I don't remember which) so I click it. This brought up a window asking me for my password and then a new window where it went through a checklist of things and presented me my network settings, which
means nothing to me. However, after this I tried Firefox again with not luck.
So I have been having this problem with my WiFi which isn't working. I am currently running on the following:
uname -a
Code:
Linux mmartin6510 2.6.31.14-0.8-desktop #1 SMP PREEMPT 2011-04-06 18:09:24 +0200 i686 i686 i386 GNU/Linux
I am also using gnome-NetworkManager. If I left-click on the NetworkManager icon down on the taskbar near the clock it shows "Wired Networks" with eth0 connected, and "Wireless Networks" is blank under the heading, last week I believe it said something like "device unavailable" or something like that.
Network Details:
iwconfig
Code:
lo no wireless extensions.
eth0 no wireless extensions.
[Code]....
I was curious about when the last time I was able to successfully use my wifi so I checked to see in NetworkManger and it just so happend to be that I was on a business trip in Atlanta on a different network then am usually connected to. Don't know if that has to do with anything but I thought it was worth mentioning.
Also, I thought it may have something to do with assigning an IP address static-or-auto but I am not too familiar with NetworkManager to check that.
I don't know what I did but I can't connect to the network any longer. KNetworkManager finds it but I can't connect. It stops at waiting for authorization. I've been connected before and it still works in xubuntu but something happened here. Here is what /var/log/messages/ says
Code:

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
I have a samba server on my LAN. It can be accessed without any problems from Windows machines on the LAN without password. I have two computers that I have updated to OpenSuse 11.2 (both used to run 10.3). Since doing this upgrade I can no longer access the samba share from the Suse machines. Basically, both Dolphin and Konqueror ask for a username and password to access "avoca" (the workgroup).

I've been running Courier IMAP for many years now, but when I added gmail's IMAP to my Outlook I noticed something interesting: when you delete a message, it gets thrown into the trash instantly.
With Courier IMAP (or any other IMAP server, for that matter), when you delete, it first marks it for deletion. Then after you Purge Deleted Messages it either gets rid of them or moves them to trash.
Is there a way to implement this in Courier IMAP?
I'm looking for a method to sync my calendars on my IMAP server with both my Thunderbird/Lightning any my Blackberry. I found "IMAP Calendar Proxy" here recently, but it has been inactive for 5 years. I've seen people suggesting the use of services like Plaxo and such, but I don't like the idea of a third party messing with my calendars and contacts. Also, I've had to remove several viruses from computers with Plaxo, and I'm not sure if it in itself is a virus or not..... It certainly is a thorn in my side as is. This is for my personal IMAP server, so I'd prefer a free solution even if it is more difficult to install than a paid version. I mainly need it to just sync my calendar to my Blackberry and Thunderbird and couldn't care less about the contacts.
I've been Googling for things for quite some time now, and haven't really found anything that says that it will work with Blackberry and Thunderbird. They really only give a sense of maybe with nothing really defined. I can put on an Ubuntu server to sync everything? I don't want to leave my computer on all the time, and RIM has yet to come out with something decent to sync Blackberries and Thunderbird properly as far as I know.
Has anyone gotten evolution to work with gmail imap? Mine says it is connecting but it never downloads any messages nor does it give any errors. I'd sure like to make it work.
View 5 Replies View RelatedI am having trouble getting evolution to work properly with my imap server. It won't show any messages. Icedove works fine, though. I'd rather use evolution because of the calendar. I'm not sure what I am doing wrong. The IMAP server is hosted by network solutions. I have screenshots of both clients. I've blacked out a few things for privacy.

In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.
As a consequence all network services are not working. I can't connect to any other machine nor to the internet.
I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.
Any suggestions how to make it work again? I'm using Suse 11.3.
