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.
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'm running a windows 2003 server to host a number of websites.
unfortunatly it looks like i didn't correctly protect the SMTP mail server
i checked the 'badmail' folder in the inetpub and found there were upwards of 250,000 bounced mails there... some spammers were obviously having a field day with my smtp server...
i've now changed the settings so that realys are only accepted from 127.0.0.1 and anonymous access is now disallowed.
my problem is that when i start up the SMTP server again spam is continuing to be sent out because the Queue folder is apparently full of junk waiting to go out...
i've tried entering this folder but the computer hangs, presumably because there are so many there...
i've tried deleting and renaming the folder but even with the smtp server turned off i get an 'Access Denied' error...
what can i do to flush or empty the queue folder ?
Due to spammer activity, I find myself with 20,000 messages in the queue and I'd really like to remove those emails from the queue as it is causing delays to good messages.
Can you give me the SSH command to remove messages by subject line please?
I have already used exim -bpru|grep frozen|awk {'print $3'}|xargs exim -Mrm and exiqgrep -i -f '<>' | xargs exim -Mrm and exim -bpu |awk '/nobody/ {print $3} ' |xargs exim -Mrm
But there are still 11,000 messages left in the queue. The spammer messages have the following subject lines:
IS THIS TRUE? PAYMENT UPDATE Online Banking Account Is Locked ! Online Banking has been locked ARE STILL ALIVE /THIS A SAD NEWS ABOUT YOU
If I attempt to remove even a small message from the mail queue, using the panel interface, the screen grays slightly but nothing happens. If I refresh the screen after several minutes, I'll sometimes get the following message:
"This operation is taking too long. Check the results in a few minutes."
Switching to Postfix eliminated the problem. But with Postfix, all of my Mailman lists (scores of them) broke, so I had to switch back -- and the problem reappeared.
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...

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.
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 >.<
my Exim mail outgoing queue is getting stuck and i cannot receive emails. Under WHM i have 50 odd emails, some 7 days old.

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.
I have a customer that wants to send emails using Exim and SMTP (using outlook), withouth authentication. Now.. the big question is ... how can I configure the Exim server to work withouth any authentication?
I know the risks of this withouth any authentication, but is my customer's server and he want to work in this way.
He is also asking if he is able to send emails withouth authentication using SMTP for certain IP addresses.. is that possible? Can be done for only 1 domain, or for the entire server?
