I would like deliver to reject certain users. Since supposedly deliver only uses userdb, not passwd, I can't use deny=yes for that. Or does userdb support deny=yes? Yes, I should rather reject them right in the MTA, but that currently takes too long to implement. Or how to reject gast* in postfix using nss authentication?

Hi list, I have noted over the last week or so my DNS servers are dumping lots of messages for bogus domain lookups.

Hi All, I'm currently playing with smtp_recipient restrictions to try and knock some of this spam on it's head. On my old debian server, I was using this and successfully filtering out at least 90% if not more of all spam emails which was great. I didn't even need spamassassin. However, trying to do the same thing on my new CentOS based server isn't working. With the

I have had the same email address since 1997 (when microsoft stole bob.com from me thanks to network solutions...) In the early days I of course was free with my email and used it everwhere. Fast forward to 2012, some 15 years later. woof..the amount of spam sent to me has always just kept getting worse and worse. On my centos 5 server I just used sendmail with spamassassin and it killed a

I need to authenticate users via LDAP either by mailaddress or login name. In both cases the mailbox location is /src/mail/%d/%n. I can easily deduct that path from the mailaddress, but not so from the login name. Can I get the mail address as part of fetching user_attrs and modify it on the fly? Something along the lines of this: user_attrs =

Hello, I'm figuring out how to auth users against FreeIPA and I wonder if someone did this without GSAPI. My users are stored in a mysql DB where I wonder what I shall use as authname, the username or the mailaddress. As the mailaddress is always unique it could be best but if a user has multiple mailaddresses under seperate domains username might be better. Any clue here and maybe an
