[ semi OT ] Bounced Mails

[Luis Hernán Otegui <lu...@gmail.com>]

Hi, List, my users are getting increasing amounts of "Mail Delivery
Subsystem" mails, and I suspect spammers are using their addresses as
senders. I have my servers registered with SPF, but now I wonder how could I
stop this mails from getting to their accounts?
I've tried to explain to them that spammers are beggining to use the
spoofing techniques used in viruses, but they're just mad at it.
Has anyone a sollution to this issue, or we must just get used to it?

BTW, I run SA through AMAVIS, on a Debian-based machine.

Thanks in advance,


Luis

The BOGUS_VIRUS_WARNINGS ruleset will filter out a huge amount of this junk.

I think Justin has some new sandbox rules that also work well, but I don't 
know which versions of SA they will work on.

I'm using milter-regex with special tailored rules. This solution works 
well here now.

I've heard that milter-null can help reduce this problem. However, I 
don't use it so I can't offer any more advice than that.

Unfortunately not much can be done about it other than SPF.
