[horde] IMP newbie question

[Peter Abrahamsen]

Eric,

Err, I think you are confused. Sendmail is a Mail Transfer Agent (MTA) - it
moves mail between mail servers, and also accepts outgoing mail from mail
clients. It only groks SMTP (Simple Mail Transfer Protocol). You always need
an MTA.

POP3 and IMAP are competing (so to speak) mail access protocols that allow
mail clients to read/fetch mail stored on a server. You can authenticate
against pop3 or imap.

IMP is a mail client. It connects to a mail backend (such as pop3 OR imap)
to retreive mail, and sends mail through an MTA, such as Sendmail.

It sounds like you want Horde to authenticate via IMP, which can
authenticate against POP3. I don't know quite what you're using MySQL for,
except perhaps preferences/sessions. If that's the case, you don't need to
do any sort of authentication with MySQL save setting up a user (ONE user)
for Horde to connect as. You should set up at least one server configuration
in IMP, then uncomment the lines at the top of registry.php to have Horde
authenticate against IMP.

If that's not the case, please correct me.
