Maildrop

maildrop is an open source program designed as a mail filter and mail delivery agent specifically for the Courier mail server software.

maildrop is a filter for the local mail delivery agent, capable of reading the messages and redirect them to user's mailbox. Optionally, it reads instructions from a file, which describes how to filter incoming mail.

The program is written in C++ and it's significantly larger than procmail. However, unlike procmail, maildrop will not read a 10 megabyte mail message into memory, as it saves them in a temporary file, and filtered from there.

What is new in this release:

• Search patterns are now MIME-aware.
• Search patterns are now specified in the UTF-8 codeset, and will get transcoded to the mail's character set, as indicated by the MIME headers.

What is new in version 2.4.0:

• maildrop/main.C (run): When using system authentication on platforms where the mail directory does not use the sticky bit, use groupid set by the set-group-id bit on the binary executable, if any.

What is new in version 2.1.0:

• maildrop's license formally changed to GPL 3.
• reformail: generate larger Message-ID: headers on 64 bit platforms. If
• standard input is seekable, don't bother wasting time discarding stdin.
• maildrop: ignore SIGPIPE if child process did not fully consume stdin.
