Exim Using 100% CPU
Aug 7, 2008
this is often happening on my new servers, with FreeBSD and exim 4.69
2 exim process start using a lot of CPU (that's not 100%, but it's like 40% for one process and 35% for other) for hours...
but, as soon as I restart exim, that stops
so it's not a high mail load on server, nor anything like that
I even checked logs to see if it was on some kind of infinite loop (auto-auto-auto-auto-reply), etc, but can't find anything out of ordinary
anyone experiencing something similar?

I am having issues in receieving emails. For some reason, the rbl lists I had setup are causing the server to reject emails (retry - timeout). So, I need to take this rbl list completely. How can I do that? exim.conf is locked and using the advanced editor is no fun even though I tried it putting the dnslists without the rbl causing the problem.

I have a dedicated server with WHM installed on it, but recently I've been having problems with emails, specifically exim.
The main issue appears to be a huge number of exim processes all running at the same time. It pushes the server load higher and higher (and when I say high I mean over 100), and basically locks everything else up until I can get a command through to kill exim.
After a bit more investigation I found that the mail queue in WHM appears to be seperate to the one I can find with the exom -bpc command, and gets full of email sent to non existant domains or accounts. So my first theory is that at some point exim tries to deliver all of these at once and that causes the massive load spikes. I don't know if that's possible, or probable, but there isn't enough legitimate email coming into the server that there ought to be any issues.
i've read about how to control the mail q from exim, but that doesn't appear to make a different to the q shown in whm. Currently the server is being held up by a cron running every half hour to restart exim automatically, but at peak times this doesn't appear to be doing enough, and at one point yesterday exim had 400 running processes.
Obviously this is causing a few problems. I don't have the technical knowledge to diagnose or fix the problem past the guesswork i've already done, so i'd appreciate any suggestions

I have some clients who own large forums, and during usage Mass Mail CPU goes up to 100%. Is there any way to re-configure the exim so not to distrupt the CPU that much?

I'm trying to diagnose some server load spikes, and I've noticed that my exim log files are getting huge (5 gigs, plus 4 gzips at 1.7gigs)...my server status shows the gzips and greps on these log files putting my cpu load at 99.9%...how do i keep these from getting so huge and/or keep them from maxing out my server?
I'm running CentOS and cpanel...

In WHM > Server Status, it shows exim as:
exim (exim-4.63-1_cpanel_maildir)
I remember it used to show more stuff inside the (). Can you tell me what it shows on your server?

I recently switched over from Virtuozzo to WHM (on a vps), and was going through some of the different pages there. I noticed one page that displays the exim stats, similar to running it through the command line. Anyway there is one section I'm not entirely sure what it's referring to.
Quote:
Top 50 mail rejection reasons by message count
Messages Mail rejection reason
311 Rejected RCPT: No such person at this address
75 Rejected RCPT: Sender verify failed 25"The mail server detected your message as spam and has prevented delivery (200)."
I'm not sure if this is referring to inbound addresses being blocked, or forged emails from my server being rejected by outside servers.

I am not actually a hosting provider but a client. I do have some technical knowledge about Exim, Sendmail etc and my host also co-operates with me so I thought of asking this question myself. My problem is with the RBL checks that my host's server performs even on authenticated SMTP connections. My ISP provides a IP to me which is being shared by many subscribers and gets blocked often. This causes a problem for me to use my mail client to send outgoing e-mail through my host's SMTP.
Suppose my hosted domain is "mydomain.com". Now when I use my e-mail client and send an e-mail using my hosts SMTP server (which requires due authentication) and give return-path (envelope sender) as "someone@mydomain.com", the e-mail passes through nicely. But when I use some other return path like "me@yahoo.com", I get a RBL block message after RCPT command. This should not happen as I am a paying member and I am correctly authenticating myself using the username & password of my hosted account.
My host uses Exim 4.63 so I just wanted to know whether there is a way to modify Exim ACL so that it doesn't perform RBL checks for authenticating users.

I've recently purchased a cPanel VPS from a company i found on this forum. However, i am not experiencing some problems with the sending of e-mails from the server via Outlook Express. Unfortunately, i'm have no real knowledge of EXIM and i was hoping someone would help me with this. Basically, when i setup the domain and then setup a email account, i could only receive emails and not send (as i was getting an error within Outlook) this was due to the fact that the domain name was not listed in /etc/localdomains, so when i added it to that file it seemed to have done the job. Now, when i send emails locally EG: example1@domain to example2@domain i t will indeed send correctly, however if i want to send it to an external domain it stays in the queue (which i can view in WHM). When i force send it, it gives me the message "Connection refused", can anyone shed some light on this situation?

2 computers, A and B
A's email address = bob@computerworld.com
B's email address = steve@computerworld.com
Both are setup to correctly SMTP AUTH using their respective email accounts.
Both are in Texas and Georgia, respectively, so they are *not* on the same network.
The problem? If Computer A sends 4 messages (or a message with 4 recipients) and gets rate limited, Computer B, that is very far away, has a separate email account all together, and a different IP address, also gets rate limited! Computer B cannot send an email at all.
I think for some reason Exim is limiting the entire domain, but it is not supposed to act that way. Why is it doing that, and more importantly, how can I stop it from doing that? I want it to limit per email address, not the entire domain.
I have tried with and without the $authenticated_id key. It doesn't seem to make a difference.
Here are the Exim logs showing the rejections:
2008-04-04 23:55:28 H=localhost ([192.168.1.7]) [127.0.0.1] F=[3]<bob@computerworld.com> temporarily rejected RCPT [4]<dd444d@gmail.com>: ...

I am having an odd problem when sending mail with an external mail client (thunderbird) through my server (CentOS 4.4) running exim 4.63. When sending mail to external domains NOT hosted on my server, such as to hotmail email's, the email is accepted and sent through immediately. However when sending mail to domains that ARE hosted on my server, such as my own domain, it takes upward of 30 seconds for the email to finally be accepted and delivered. Thunderbird will just sit there at "connected to mail.eggycrew.com" until it is finally sent.
I've done a bit of research and haven't found anybody having this issue before.
