Just what the doctor ordered
Last week I sealed up a gaping open relay hole in our mail server, but naturally sendmail was denying SMTP to roaming users. I spent all weekend thinking "Gee, why doesn't someone just write a script that parses the mail log, extracts POP3 validated IP address and appends them to the /etc/mail/access file?" Then someone said, "go to Freshmeat. I bet it's been done already." Well, lo and behold, it has, and quite well I might add. Everything worked as promised with only very minor editing required to reflect the differences in my filesystems.
Thanks to POPauthd, I can sleep at night again. Highly recommended.
