AqMail 0.9.1 Beta

AqMail fetches mails from remote mailboxes (POP3), applies admin-defined filters, and stores the email in local mailboxes for POP3 daemons to serve them.
AqMail project supports virtual mail domains and users. It has been tested with QMail as the MTA and with Spamassassin and ClamAV as filters.
Main features:
- supports virtual users and domains
- supports multiple remote boxes per user (mails can be gathered from remote boxes into local boxes)
- individual fetch intervals for every remote box of every user
- system-wide, domain-wide or per-user filtering of mail
- ordering of mail filters
- simple interface to filter scripts (basically "FILTER INFILE OUTFILE")
- POP3 client plugin with APOP or USER/PASS authentification
- maildir plugin (reads and writes maildir folders)
- tested with QMail, SpamAssassin and ClamAV
You can use AqMail to gather mails from multiple email accounts into a single account which can then be accessed via a webmail interface (e.g. OpenWebMail) or via a POP3 server (e.g. QMail).
AqMail can be used as a daemon which continuously fetches, filters and distributes mails. It can also be used in command mode (e.g. to fetch mails and store them directly to a maildir in order to just replace the tool fetchmail).
AqMail is running on my own system in combination with QMail. However, any mail transfer agent which is able to serve from maildir folders can be used.
Enhancements:
- The daemon mode has been improved since 0.9.0beta.
