Anyway after complaints of "mail not being sent" I looked at a few things, found over 25,000 messages stuck in the queue. The messages no being sent thing is yahoo blocking me because of too many mails sent to their servers without a valid recipient.
When I empty the queue it gathers about 200 mails an hour. Looks like it is coming from all over the world and they are using a valid ip from one of the domains hosted for sending.
Bear with me I was reselling for years and this is my first real dedicated server.

Today my server started to go off-line and each time i restarted it went down within couple minutes. So i looked into it and found that i had over 7000 emails in Exim Mail Queue. All of them are spam. I deleted them through WHM and now everything seems good again but....
My question is how can i check what caused this problem? Has one of my domains been compromised with and sending out spam? What can i do?
1) What would you guys say is average in terms of the # of emails in the Mail Queue?
2) What steps can be taken to tighten it up? If I start with a clean slate, it only takes about a week or less for my mail queue to reach 1000 or more. Most of it seems like junk mail.
my Exim mail outgoing queue is getting stuck and i cannot receive emails. Under WHM i have 50 odd emails, some 7 days old.
A small dump from /var/log/exim-mainlog is below:

Everything was fine until about 7 days ago, i dont know why the config didnt change but since then its been dropping received emails and queueing on sends.
This feels like an unusually newbie question for me, but... I think my exim queue isn't running. I was born and raised on qmail :-)
I discovered on a relatively new server that the message queue was backed up nearly a month with messages. Fortunately it wasn't a crazy amount, some were double-bounces, and with the help of exiqgrep I got it caught up manually in about a day on and off.
But today it's obvious messages that fail the first time (ex: greylisted) NEVER get retried. Is this a missing cron job? Or command-line param for exim? I would think a relatively stock cPanel install wouldn't suffer from this but... where do I start checking?
Code: /usr/sbin/exim -bd -oX 587
2008-03-09 04:02:15 exim 4.68 daemon started: pid=13511, no queue runs, listening for SMTP on port 25 (IPv4) port 587 (IPv4) [127.0.0.1]:10025 I mean, that seems fairly obvious right there, but I want to make sure I fix it the right way... in case this is merely a checkbox in cPanel or something...
I have been seeing so many exim mail queue on server. I would like to clear for every one hour throuh crontab entry. So that I have used following script to run.
can it be done? because a dumb customer sent an email with like 500 recipients... and its stucked on the queue. So i wanna delete it... but when i go to Mail queue manager (i use WHM) i got this:
Message 1KRTsr-0006tc-F6 is locked
So what can i do? should i just sit and wait until its "unlocked"?
can i kill any process? i already tried restarting exim... but its still there... and btw the size of that message is of about 500 mb >.<
We have running exim mail service in cpanel web server. Exim consumed some CPU% memory and lots of threads are opening. More than 2000 mails in queue everyday. How can we optimize the exim mail service?

I notice that in my WHM Mail Queue Manager I get a few emails pointing to something that looks like this:
Quote:
Everyone looks like this, 1FnPkc-0000rR-VQ 516 22h Delete Deliver Now root@host.mydomain.com
and also some emails going to root about backup etc.
I don't have any email addresses set in the "Change System Mail Preferences" options, I left it blank. Should I set a valid email address or is there any way to stop these emails being sent in the first place?
Recently, I keep getting an email from my dedicated server company (godaddy, plesk 8.2 windows) that I've reached my daily limit of 1000 emails when I only send like 20-40 a day max.
So I want to take a look at whats going on, what emails have been sent/received and are still in queue?
Can can I access my mail queue using Plesk? And then how can I delete them?
my friend has an vps and he has some trouble sending mail to 1 particular host such as hotmail, all the remaining hosts the mails are sent, but only to tht particular mail host the mails are not sent regularly, some times they recv it some times they don't
checked webmail, couldn't see any failed/bounced mail mail msg, so not sure why this is happening, so I want to check the mail-queue for him to check the status of tht particular host, if I could try to sort them out directly with the mail server for him.
I had this spam problem on my server. Some perl scripts uploaded to /tmp folder were generating lots of spam email. We stopped sendmail, cleaned the server from all the bugs and erased all the messages in /var/spool/mqueue. Yet when I start sendmail again I begin receiving lots of autoresponders and returned emails. Where are those incoming mails located? In which queue?
