General :: Exim Setup For Large Outgoing Mail Queues?
Apr 25, 2011
I have a fairly standard Exim setup for inbound and outbound mail. Recently our development team has put together a PHP app that allows us to send out bulk mails to our clients. The PHP app uses standard PEAR libraries to initiate an SMTP connection to localhost (application and mail server are on the same box). The idea here is that the application will send out roughly 10'000 emails in a very short time period (60 seconds or so) which Exim will then hold in its queue for delivery.
The problem comes in where after about 50 emails, Exim stops accepting mail and loggs the following error in the exim_main.log file: SMTP command timeout on connection from localhost [127.0.0.1] Could it be that this is because Exim immediately starts delivering the mail and then stops accepting new incoming connections? I thought that increasing the SMTP limits may be the problem here, but even after setting new values in the exim.conf file to the following, I still get the same problem:
queue_run_max = 5000
smtp_accept_max = 5000
smtp_accept_queue = 5000
This begs two questions: How do I resolve this? What is the best way for configuring Exim to accept a huge amount of mail into the queue in a very short time period, but then gradually delivery it once it's all in the queue? I've seen some people run separate Exim daemons for incoming and outgoing mail; is this a good solution?
I have 3 ip address on my VPS and I need to change exim configuration to listen only on one ip address. VPS have WHM and Cpanel installed.I changed in exim configuration interface to my ip.
I cannot get exim4 to actually deliver any "local delivery only; not on a network".But whatever I do in the config, all mail gets frozen with entries in the log file like:"root@empty R=nonlocal: Mailing to remote domains not supported"Maybe the problem is that there is no fqdn for the computer (and will never be). How can I enable local mail delivery?
I am trying to do something really simple with Exim. I have two machine connected together via a hub. They can ping each other. They each are running openSuse 11.2 and have Exim installed. On each machine from the command line in start Exim as a daemon by typing: sudo /usr/sbin/exim -bd -d and each machine runs through some output and sits there "Listening". Then on either machine I try to send a mail message of the form mail
(or mailx) <user>@<other node> some text EOT
and absolutly nothing happens! I must be doing something wrong or daft which is very basic, but I have searched all over and cannot get it to work.
Has anybody else seen this kind of attack? I see those messages on 2 exim mailservers. Looks as if someone sends a 50MB big mail header :S What is their goal except from increasing my traffic?
Code: 2011-02-12 07:48:53 SMTP protocol synchronization error (input sent without waiting for greeting): rejected connection from H=ns33.medialook.net [91.121.108.5] input="GET / HTTP/1.1 Accept: */* Accept-Language: en-us
I've setup Exim4 as an MTA on my VM which has a static IP. I've pointed the MX records both idential to this static IP. I can send out via command line on the VM using Exim commands and receive the mail in my home account no problem, it also displays the correct from address ie rich@mydomain.co.uk
So I'm not sure what's going on with receiving the mail. If I send a mail from my home email to rich@mydomain.co.uk (not real address), I don't get a bounce or anything, it just goes out never to be seen again.
We moved over from Cpanel using Exim. I was wondering if anyone knew of way to convert the mail so when a user logs in they get to all their mail in their folders. I notice exim has a ton of folders while postfix creates files that act like folders which contain all the emails. I sent up 1 of the emails into the our mail folder that was created by Exim and it can be Subscribed to in Outlook with imap but the emails inside doesn't show up. They both appear as text files so I don't know what the difference is.
I run a mailserver and this is bothering me quite abit. Being going on for about a month now. Running exim4 and dovecot with exim4u. This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

I run OSX on my everyday computer so this is not me sending out stuff since the above mail says Microsoft Outlook express has sent it (?) Running a Debian Squeeze server. And I really dont get any other spam due to exim4u setup and spamassasin.
I recently built a mail server with Slackware/Sendmail and basically all works. Mail comes in and goes out. The problem I have is 3 email addresses cannot be sent to from this server. The remote ends are 3 different servers but all run Exim 4.69. I have logged the server exchange and this is what I get: (names have been changed to protect the innocent!!)
can i just copy/backup postfix mail queues in /var/spool/postfix and paste that folder back in after i done migrating all users and mails to a new mailserver?
I have searched for at least 1h for this to find but I didn't found anywhere how can I do to check for large email mail boxes. I run qmail as mail service
I am trying to setup a sendmail server on my dedicated server. It was pre-configured to use exim from cpanel. Is it possible to use exim for all emails from a a certain domain i setup on the server and sendmail for others?
ex. domain1.com -> exim domain2.com -> sendmail
If it is possible can someone let me know how i would go about doing this? If it is not how would i disable exim and use sendmail for all mail?
to avoid automatic start of this mail server (I use qmail). After several months, I did a reboot and exim is started! Looking at the history, I found this command:
Quote: dpkg-reconfigure exim4-config
Maybe this command has restored the init script of exim?
Exim: Is there away to block command when someone telnets to exim's port? Email won't send out unless they authenticate, but if there a way to total block them from typing all together, but still allow the server to receive email? IE, to block this:
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?
I'm using Debian 5.0.4 with shell access only, exim4 and mutt. I would like 'all' outgoing mail sent by any/all users to be auto'ed CC (not BCC) to a specified e-mail account for auditing purposes. I do have it working for BCC using 'unseen', but I really want it be CC. I have spent hours of searching/reading/testing and have not been able to find out how. I have seen it done on other shells I've been on as a user; any mail that I sent out, I did not see it was being CC'd but once the recipient received it was also addressed 'toaddr@thatshell.com').
It's not practical to add an alias for every user on the system (/etc/aliases) and to remember to do so each time adding a user. If I set in etc/profile alias mail= mail toaddr Users can still find ways around that.
I have a small home network running mail agents Evolution and Thunderbird, and connected to the internet via Comcast. Originally I used my campus office computer as a mail server, but encountered problmes because Comcast started blocking port 25, allegedly because of span problems. I need to change the setup on my campus office computer so it uses port 587 when functioning as an outgoing mail server.
Can anyone recommend a tutorial which tells me everything to do in order to accomplish that?
At present I'm, using Comcast's outgoing mail server, but I started having problems with sporadic blokage of outgoing mail with attachments, which Comast can't explain.
I created a signature, for my outgoing mail, in Composer Preferences but it don't show when I create a new mail. how to get the signature in my outgoing mail, it would be nice to share.
I m using sendmail-8.13.8-2.el5 along with MailScanner-4.79.11-1
i want to set a rule so that user1@mydomain.com can send only to anotherdomain.com domain. sending mail to any other domain will be rejected. can it be done by sendmail or MailScanner ??
I'm setting up a server and trying to make it *very* secure. Before I configured my web stack, I was about to install some security packages, Tiger and Samhain, but these packages wanted to install sendmail so that they can send outgoing notifications. From the reading I've been doing, I believe I want postfix instead of sendmail. It is my (perhaps mistaken) belief that installing postfix first will prevent them from installing this sendmail I do not want.
I want to install postfix with the following goals in mind:
* let PHP scripts send mail using the mail function.
* various system notification functions (cron, etc.) will be able to send their emails
* emails destined for root@localhost will be redirected to admin@mydomain.com
* let tiger and/or samhain send their notification emails
* NO INCOMING OR LOCAL MAIL IS PERMITTED. Because mail for my domain is handled by google apps, nobody will be checking mail on this server. Also, this server has very limited disk space. It is therefore very important that we don't have mail accumulating in boxes that will never be checked.
* no unnecessary ports, services, or cron jobs are running.
I've been reading a variety of pages that describe postfix setup on Ubuntu but these articles are imprecise, incomplete, and describe installation of things I don't want like POP/IMAP/etc.
There's also one final wrinkle. I will be setting up postfix to send via Amazon SES.
I have installed a sendmail server on fedora 10 I try to configure my sendmail server as a mail server to send outgoing email using port 587( because port 25 is blocked). after finishing configuring my sendmail server, i checked out my sendmail server using telnet localhost 587, and it worked fine as below code...
I have tried two different ways for user name: name, or name@mail.mydomian.com, but not working at all, the two results are the same. PS: I have test port 587 and can use port 587 and Kmail to send outgoing mail using other external relay server
is my wrong configuration for sendmail server or kmail?
I just set up a new router for our home office. I've enabled traffic logging, and I'd like to have the logs emailed to me. However, in order to configure email-notification, the router needs and outgoing mail server. Forgive me, but I don't really understand the terminology being used here. I've googled this a bit, but I'm not sure I now what "outgoing" vs "incoming" mean in the context. I tried using my gmail account as the outgoing mail server (smpt.gmail.com) but it requires TTLS encryption, and there's no option for that on my router.
So I figured I'd setup a simple mail server on my local network. I have a dedicated server machine, so I'd just configure a mail server there. But I got stumped at the first input box (in the yast module):"Outgoing Mail Server".That's what I wanted to use this server for. What is this "outgoing mail server"? I understand it in a normal emai context (I think) but this is confusing me. I've read through the HowTo on the openSUSE wiki, but it still doesn't answer this question.Isn't there some way to have a simple, local mail server (without MX records and the like) so I can send email from a local machine?
I've got a web server that's hosting a few sites, and there are a few WordPress instances with these sites. With Wordpress, whenever a user registers with the site, they receive an email.With my server, it sends mail via Sendmail. This is all fine and good, except no matter what, it's flagged as spam. Is there any way to correct this?Keep in mind that this isn't a mail server, and the only reason the server ever sends mail is for new wordpress users and password resets.
I have setup mail server on Ubuntu 9.10 and it's is working fine.I am using Webmin to addministrate my mail server.My Ubuntu server name abcs.I send a test mail from Wedmin for user gom.Why it keep adding InfoNet. What I would like is setup as gom@abcs.com.
I'm going crazy with this one. For whatever reason, sendmail will not authorize any users. I've tried multiple logins (all with good credentials) but still get login fail, ie (FYI this is a sendmail/MailScanner setup if it makes any difference):
220 hostname.net ESMTP Sendmail 8.13.8/8.13.8; Fri, 19 Nov 2010 12:07:08 -0600 ehlo hostname.net 250-hostname.net Hello testdomain.com [123.123.123.123], pleased to meet you
Im trying to get postfix to filter my outgoing mail and basically drop everything that is not in my hash table.
So far I managed to get this going
Code:
Code:
Unfortunately those rules also apply to incoming messages. My goal is to disallow users on my host to change their "MAIL FROM" to anything they like and restrict them to domains I specify. I'm aware that the local part still is variable and a user of domain "foo.com" could use a email of domain "bar.com", but still some of my troubles would be solved if I get this running.
Working in a SW company. guys transfer their codes through email outside the company. mailserver running on postfix. Is there any method to filter mails according to contents of attachment not by file extension.
As a part of migration I am proposing different scenarios to my organization. One which is asked to prepare is to configure multiple mail servers to handle incoming and outgoing mails. Say I have -[URL], I need to have accept mails from [URL] and send mail from [URL].
