Fetchmail

Fetchmail is a full-featured, robust, well-documented remote-mail retrieval and forwarding utility intended to be used over on-demand or permanent dynamic-address TCP/IP links (such as SLIP or PPP connections). It supports every remote-mail protocol now in use on the Internet: POP3, IMAP4r1, ETRN ... [More] , and ODMR, all with various authentication variants, and TLS/SSL security with certificate verification. Fetchmail retrieves mail from remote mail servers and forwards it via SMTP, LMTP, or to a local delivery agent. Mail can then be read by normal mail software such as mutt or alpine. This setup allows all your system MTA's filtering, forwarding, and aliasing facilities to work just as they would on normal mail. [Less]

Cyrus IMAP

The Cyrus IMAP server differs from other IMAP server implementations in that it is generally intended to be run on sealed servers, where normal users are not permitted to log in. The mailbox database is stored in parts of the filesystem that are private to the Cyrus IMAP system. All user access to ... [More] mail is through the IMAP, POP3, or KPOP protocols. The private mailbox database design gives the server large advantages in efficiency, scalability, and administratability. Multiple concurrent read/write connections to the same mailbox are permitted. The server supports access control lists on mailboxes and storage quotas on mailbox hierarchies. [Less]

[More] Also supports a scalable connection pool to limit the database connection load under high concurrencies. [Less]
