| smtpd | Mail proxy for firewalls with anti-spam and anti-relay features | Mehr ... |
Smtpd uses two programs, smtpd which listens for incoming mail and places
it in a private queue, and smtpfwdd, which invokes sendmail to deliver
messages from the queue. The configuration file for smtpd has powerful
features for controlling the acceptance of incoming mail.
.
It is particularly useful for firewall sites, where the policy aspects of
which mail should be accepted (in smtpd's configuration file) are clearly
separated from the routing and other aspects of the mail configuration
(which remain in the sendmail configuration file)
.
It can be used with any mail-transport-agent which can be invoked as sendmail
but is intended to integrate with the Debian sendmail package, which
recognises when smtpd has been installed.
.
If you are attempting to use it with an MTA other than sendmail then you
will need to be prepared to modify the MTA configuration. |
