E-mail questions / problems

[HostingGrounds]

Hi there,

I have a few questions about the e-mail in DirectAdmin.

1) My customers, including myself, receive some e-mailmessages several times instead of one time. I don't know what causes this. I restarted exim a few times, but that doesn't solve the problem.

2) I get a lot of errors in my Exim paniclog:

...
2011-07-11 12:12:35 queue run: process 387 crashed with signal 11 while delivering 1QfAWU-0001Zh-RQ
2011-07-11 12:12:36 queue run: process 396 crashed with signal 11 while delivering 1QfBcU-0001Ee-Tt
2011-07-11 12:12:36 queue run: process 419 crashed with signal 11 while delivering 1QeyyP-0005lT-2o
2011-07-11 12:12:36 queue run: process 428 crashed with signal 11 while delivering 1QehUP-0000iD-BP
...

It looks like Exim is crashing alot or something. What is the cause of this?

3) My server is being spammed at one e-mailaddress, let's say [email protected]. All the e-mail of domain.com is being forwarded to another Gmail address. The settings in SpamAssassin however show me that spam must be deleted if Spamassassin reconises it as spam. That doesn't work. The spam is forwarded to the e-mailaddress aswell. Why?

4) As said in #3, my server is being spammed. How can I block the IP-address where it is comming from?

5) How can I empty my mailqueue in one time? It is filled with spam messages.

I have DirectAdmin v1.39.1

Can you guys help me with these issues?

Thanks in advance.

Hello,

You might need to reinstall exim from sources or with custombuild. Search the forums for detailed instruction on both things.

As for the blocking, I'd use IPtables to block the IP address. Search on google how to block an IP with iptables or install a firewall plugin like CSF (http://www.directadmin.com/forum/showthread.php?t=29807)

And why spam is being forwarded; I think spamassassin doesn't filter mail on forwarders.

And how to clear the mail queue, see http://www.directadmin.com/forum/showthread.php?t=15623

Check your logs. Most likely you've got got a mailbox and a forwarder delivering to another mailbox which you also check. DirectAdmin treats virtual user forwarders by forwarding, it treats mailboxes by delivering. So if you've got both for one virtual use, the mail will get delivered twice.

2) I get a lot of errors in my Exim paniclog:

Check your mainlog to see what exim is doing immediately before crashing.

3) My server is being spammed at one e-mailaddress, let's say [email protected]. All the e-mail of domain.com is being forwarded to another Gmail address. The settings in SpamAssassin however show me that spam must be deleted if Spamassassin reconises it as spam. That doesn't work. The spam is forwarded to the e-mailaddress aswell. Why?

User Arieh is correct. Email not deliverable on the server is not run through SpamAssassin.

There may or may not be a way to rewrite exim.conf to change this, but I haven't studied it.

4) As said in #3, my server is being spammed. How can I block the IP-address where it is coming from?

Arieh has given you one way to do it using a firewall; I use the capabilities of the SpamBlocker exim.conf file for DirectAdmin, Version 4, as discussed elsewhere on these forums and also on my site, here (nobaloney.net).
