Hi all....
I would like to switch to CENTOS Postfix from sendmail. My current sendmail, in combination with
the very old obtuse-smtpd, allows me:
To control who of the internal users can send mail and
You could control access by requiring them to send via the submission port (587) with smtp-auth either using sasl or dovcot and postfix.
To control who of the internal users can receive mail andfrom which domain or accounts
I think would require some work using Chip Salzenberg's deliver program, procmail, or some such MDA (Mail Delivery Agent) behind postfix. Off hand I can't think of how one would do this directly with postfix.
To obtain a copy of all sent mailsTo obtain a copy of all received mails
These two could be handled using always_bcc in postfix's main.cf.
Obtuse-smtpd is very easy to configure and very effective. It takes control of all smtp activities over Port
25 and, after filtering and checking, passes the safe mails to sendmail for final delivery. Obtuse can, also,
check for addressability, through DNS, of the mail sender and other useful features.
Postfix gives lots of options for incoming filtering using DNS, amavisd and clamav etc. There's extensive documentation on the postfix web site, http://www.postfix.org/
