We're thinking of switching from our old qpopper to ipop3d. Our qpopper accepts kerberized connections on port 1109, kpop. Grepping the UW source doesn't turn up any references to "1109" or "kpop"; can ipop3d do authentication via kerberos?
Yes.
Does it do so over the plain POP3 port, 110?
Yes.
If so, would it be easy to modify to use 1109 instead?
I don't know what the requirements of port 1109 are; nor in fact do I have any clue as to what kpop is that's any different from a POP server that either uses the KDB to do plaintext password authentication or supports SASL.
If it's just a POP server with Kerberos, then it's just a matter of [x]inetd configuration and not ipop3d at all.
If, on the other hand, there's a special undocumented command to authenticate with Kerberos, then you'll have to write code to support it.
