I switched from sendmail 5 years ago or so. I vaguely remember the access list, so, there's probably someone more qualified to comment, but, http://www.postfix.com/SMTPD_ACCESS_README.html covers some of the ACL tricks. Postfix packages from CentOS's postfix package also has an /etc/postfix/access file, which is worth checking out, looks to be a two column list with email address, domain, hostname or ip on the left side, and an action on the right. Might be drop in, or close to the access list sendmail uses.

There is one question I would have about switching to postfix, and that would be the compatibility of a long (VERY LONG) access control list (for the access file in sendmail) in postfix, and what the differences in access syntax that there may be. I'd kindof like to switch (to transition to the packaged kolab environment, which uses postfix), but the ACL thing (which I've not found in the various and voluminous postfix FAQL's) is the only real hangup. -- Lamar Owen Director of Information Technology Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxxx http://lists.caosity.org/mailman/listinfo/centos
