Dovecot 是一个 Linux/Unix 下开源的 IMAP 和 POP3 邮件服务器软件，支持多种认证方式，在安全方面尤为出色。 
Dovecot 2.0.3 新特性： - dovecot-lda: Removed use of non-standard Envelope-To: header as a default for -a. Set lda_original_recipient_header=Envelope-To to returns the old behavior.
- Added support for reverse quota warnings (i.e. when quota goes back under the limit). This is enabled by adding ‘-’ to beginning of quota_warning value. Based on patch by Jeroen Koekkoek.
- dovecot-lda: Added lda_original_recipient_header setting, which is used for getting original recipient if -a isn’t used.
- dovecot-lda: Added -r parameter to specify final recipient address. (It may differ from original address for e.g. aliases.)
- Maildir: uidlist file can now override message’s GUID, making it possible for multiple messages in a mailbox to have the same GUID. This also fixes dsync’s message conflict resolution.
- dovecot-lda: If destination user isn’t found, exit with EX_NOUSER, not EX_TEMPFAIL.
- dsync: Fixed handling \Noselect mailboxes
- Fixed an infinite loop introduced by v2.0.2’s message parser changes.
- Fixed a crash introduced by v2.0.2’s istream-crlf changes.
