[tpop3d-discuss]PAM domains

[Rick Stewart]

I've been using PAM authentication with my users for a while, and
recently implemented domain usernames, so that users log in with their
full email address instead of just the local part.

tpop3d rejects these usernames, and I'm wondering if there's a good
reason. Doing "virtual" domains this way works really well, and not
checking in auth_pam.c whether there was a domain supplied or not
doesn't seem to do any harm.

I'd love to hear your thoughts.

Here's a patch that makes it work for me -- I'd love to see this or
equivalent in the main distro at some point:
