Hi all,
What should be a better choice, and why? qmail-pop3d or courier-pop3? It seems that courier is a more mature option, and you dont have to patch it to understand maildir quotas.
The main reason to use qmail-pop3d is so you can use vchkpw. There are several features that vchkpw has that courier-pop3d (via authvchkpw) does not (notably logging options, also learn passwords, among others). Also, qmail-pop3d uses multilog, which is easily graphed with mrtg.
However, courier-pop3d has built in maildir support, and tls support. No patches or stunnel required. Both work well, though. I don't think one has a security performance over the other. I've never done performance testing on courier-pop3d.
Regards,
