problem with incoming spam to my server. Causing high load that eventually take down the server.
Since I don't use the server for my mail (I use Gmail), can anyone let me know the easiest way to stop/block all incoming mails to the server? I still need outgoing mail, though. Some of my PHP forms need it.
Right now, I stopped Exim to save the server (if it runs, load can get to 900+).
Today I try to fit all FW rules to my need. After i blocked the traffic "allow other incoming traffic" in the Plesk FW i dont get folders listed via FTP. The FTP client connect to my server, but listing content times out. After allow other traffic the content get listed. The rule "Allow FTP connections" ist in all enabled all the time.

I am wondering is there is a way for exim to reject those emails when the user attempts to do so.
My server is sending all emails via exim smarthost to other specialised exim server (both cPanel). How may I limit customers from sending out SPAM ? Mean to scan outgoing emails and delete/store in some folder which ones identified as SPAM. Preferrably the scan part to be on exim email proxy cause it is much idle.

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?

We switched to a 3rd party mail server provided by our local ISP, however when attempts are made to mail anyone on our domain a message similar to one of the following is received:

Hi. This is the qmail-send program.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<my_email_address@our_domain>:
70.43.63.21 does not like recipient.
Remote host said: 550 5.7.1 <my_email_address@our_domain>... Relaying denied Giving up on 70.43.63.21.
I've made sure the MX records are in place on our nameserver, and I've verified this with DNS Stuff.
I seem to think the problem is on our ISP's end.
I wonder if there is any chance to change the domain that is being shown as the incoming/outgoing mail server to users of the Plesk Panel, when clicking on the "Info"-Icon near an e-mail-account in the mail list (see screenshot).
We only have a SSL certificate for one domain and want our customers to use this domain in their mail client settings, so that the client trusts the domain.
