Greetings
Running Centos 4.8 with Sendmail+Mimedefang+spamassassin
Like most people, we use an aliases.db for a variety of reasons
(postmaster, abuse etc).
We also have some large alias lists such as "staff", "typing" and the
ubiquitous and frequently used "everyone".
Unfortunately, some piece of perambulatory pond scum has discovered this
and we are now getting spam addressed to these aliases.
Is there any way in which we can restrict the use of certain aliases to
internal email addresses / ip addresses only. Any other suggestions?
TIA
Nigel.
