SUMMARY: sendmail wrappers
This is a great list. Received responses in less than 2 hours.
Thanks for everyone who responded.
My original question was:
>I want to know if there is some kind of "wrapper" for sendmail.
>I would like to "filter" my incoming mail. (e.g. I would like
>to restict some users or domains from sending mail to a specific account)
>This "wrapper" should read the *To* and *From* fields and decide accordingly.
There is a mail filter utility called procmail.
The messages still come in, but are thrown away if the 'rules' say so.
It can be found on almost every usenet archive.
It can be found also in:
ftp.informatik.rwth-aachen.de
/pub/packages/procmail
Another approach to the problem is using a tcp wrapper.
tcp wrappers will restrict e-mail from certain hosts if you run sendmail
from inetd rather than as a standalone daemon. Suggestions for this are in
the tcp wrappers documentation.
Wietse Venema's tcp wrapper can be found at:
ftp://ftp.univie.ac.at:/systems/unix/security/wrapper
It contains some general security papers, plus the wrapper and
documentation.
Thanks again to everyone who answered.
Great list!
