IIRC, It does not do IMAP, it does not handle secure connections, it does
not ...
Squirrelmail does support IMAP. I'm using it to access a courier IMAP server with no problems.
From
http://www.squirrelmail.org/about.php
"It includes built-in pure PHP support for the IMAP and SMTP protocols"
I found the Horde system to be a huge pain to set up and install. Maybe that has changed since I tried it a few years ago but I was quickly up and running with squirrelmail in just a few minutes so that's my recommendation if it does in fact support multiple pop accounts. Alternatively, you could always use something like fetchmail (http://catb.org/~esr/fetchmail/) to pull the multiple pop accounts down into a single account and then check that one account via webmail. Might give you faster access instead of having your webmail app doing pop accesses to a bunch of different accounts?
