I don't know if I am posting this message in the correct forum so here goes. Forum admin please shift to correct forum if necessary.
I have searched the forums.
I am a relative novice with SME and Linux.
I recently checked my mail log and found a huge list of messages as follows. Hundreds an hour.

I am running Fetchmail version 1.3.4-10 on an SME 7.1 server in server only mode to retrieve POP email from an external mail server.
I don't know if this has anything to do with the these messages.
Any clues?
Thanks in advance

Welcome to the forums :)
Can you please tell us a little bit about your server and how it is configured? At first glance, it looks like something is trying to use your server as a spam relay -- but I could be wrong about this.
-
Thanks for the welcome and reply.
That's what I fear.
Information is as follows.
I set this SME 7.1 machine up for some friends who needed an IMAP mail server using the Fetchmail contrib checking their web and mail hosting company. The amount of outgoing traffic on their broadband connection doesn't seem to reflect the amount of traffic that would have to be if it was being used as a spam relay.
The SME is a standard server install apart from the Fetchmail contrib mentioned.
I am tempted to reinstall and restore their email and see if it continues.
They have had an issue in the past in that I think there domain name was being used as a return address by some spammer so I am wondering if this is a consequence of that predicament. At one stage they were receiving hundreds of spam emails an hour (which the SME was successfully filtering) until they requested spam filtering at their ISP.
What other info might be helpful?
Thanks
Gary

You should definitely upgrade to the latest version, 7.4.
I also have a few more questions:
1. Is SMTP authentication enabled for users, or can anyone access the service?
2. Is the server operating in Server Only mode?
However, all that said I agree with your hypothesis that...
... [their] domain name was being used as a return address by some spammer so I am wondering if this is a consequence of that predicament.
I would upgrade to 7.4, and update fetchmail to the latest version (in the smecontribs repository), as a first step. 7.1 is very old now.

I agree..
before you do it, please read here (http://wiki.contribs.org/SME_Server:Documentation:FAQ#Updating_from_SME_7.x_to_SME_7.2)

I also have a few more questions:
1. Is SMTP authentication enabled for users, or can anyone access the service?
SMTP authentication is for internal users only so I don't think it can be used as a mail relay from an external source. They are running an all Mac shop and their machines are not on 24/7 so I assume that it is not one of their internal machines being a spam zombie.
2. Is the server operating in Server Only mode?
Yes it is and only being used as a mail server - nothing else.
However, all that said I agree with your hypothesis that...

Yes I will do that this week and report my results back here.
Thanks for the help - nice to be part a community rather than thrashing around the whole interweb trying to find a starting point.
Cheers
