After getting incoming pop3 Email, email on server is deleted. Any way to stop this?

Hi, I did a clean Windows install this weekend and everything seems to be working well, despite the fact that I'm a totally new to this. I do however, have some questions: 1) In my setup OTRS is retrieving POP3 emails from my ISP provided server. After retrieval OTRS deletes the messages from the server. Is there any way to have OTRS leave them on the server? 2) Also since the ISP has no built in spam filters, we generally receive 100+ spam's per day. Is there any way to pre-filter them before they get into OTRS? Related to this: can we delete the spam messages from the Junk queue? (I now have 400+ junk emails!) Thanks for any insight you can offer... BJ

OTRS itself doesn't delete the email from the server, the POP setting does. Any POP client by default tells the server to delete email it has already retrieved, and the server (by default) will only allow a POP client to retrieve new mail. So depending on either of these settings (client or server) who could get into the situation where you keep downloading the same emails over and over. I don't know the answer to your question though so I'll leave it to someone who may. I'd imagine it'd just be a setting change in the OTRS POP perl script that's called when OTRS cron's the POP script.

Yes, but that depends on what MTA you are using. If you are using sendmail, you can use a milter to call ClamAV and SA to do the scanning for you, or do it all through procmail. Other MTA's (exim, postfix, etc) handle this situation also but the point being that you do this at the MTA level. Michael.

Michael,
Thanks for your reply. Now that I have thought more about stating the
question, I forgot to mention that I have the SendmailModule set to use
SMPT, not the default of Sendmail. I think it has something to do with the
Windows install.

Hi BJ,

Ok, if it's SMTP then your mail is receiving these messages directly from another SMTP server? In SMTP transactions nothing is ever stored by default on the sending MTA, once the receiving MTA receives the message, the sending MTA deletes it from its mail queue. Being sendmail you can also use a milter for the virus and spam scanning, or configure procmail to do it. Regards, Michael.

The general answer to this (this question is asked quite frequently on this list) is to setup your mailserver so that mail to your OTRS mailbox is *also* forwarded to another mailbox for archiving. I really don't recommend to leave all messages in the OTRS mailbox. First of all I don't know if OTRS really handles this setup well and performance will be a lot worse too. Nils Breunese.
