Do you have a "wildcard" mail account set up with your mail host? If
so, change it to have only the addresses / aliases you wish.
Unfortunately, no. Anything to my domain gets through.
You're going to have a hard time with this, then. I really don't recommend
it. Why can't you have the host set up email addresses/aliases/forwards for
all the accounts you need to use?
They have Spam Assasin which does a pretty good job on everything but
this recent rash of legit looking bounce messages (from Postmaster or
MAILER-DAEMON.)
They are legit bounces. To spam, which you didn't send. But that's not the
recipient's mail server's fault - although I do think in this day and age
it's probably a good idea for everyone to disable NDRs in the first place as
they've been used so much for evil.
I use Outlook for some of them based on looking for Postmaster but
many of them append their domain, typically MAILER-DAEMON@... f
example, and I found that Outlook appears to only find the whole
words.
I am looking into switching web hosts.
Thanks for the help, I will look for some more sophisticated anti-sapm
software or just switch to a web host that offers more complete mail
support.
Postini, or something, might help. But your wildcard is always going to be a
problem. Anyone can spoof the sender - and in your case, the sender could be
*anything*@yourdomain.com and *you* will get the NDR.
