queue_repair features include:
- automatic, dynamic determination of UIDs and GIDs.
- automatic, dynamic determination of conf-split; can be overridden on the
commandline to change the conf-split of an existing queue without running a
parallel, temporary instance of qmail for queuelifetime. Just recompile and
stop qmail, run queue-repair, and restart qmail.
- automatic, dynamic determination of use of big-todo; can be overridden on the
commandline to change an existing queue as above.
- handles basic tasks like fixing a queue restored from backups, incorrect
ownership or permissions of directories and files, missing or extra split
subdirectories, unexpected files or other direntries, or creating a valid
queue from scratch.
- can run in repair or test (report-only) modes. The default is test mode.
Log onto a popserver to see a list of all messages that you have on there, with
sender, subject and size for each message. With an ncurses interface that
easily lets you scroll through them, and optionally deleting messages without
ever downloading them. This can be useful when you've received big mails that
you don't really want to download.
POPFile is an automatic mail classification tool. Once properly set up
and trained, it will scan all email as it arrives and classify it based
on your training. You can give it a simple job, like separating out junk
e-mail, or a complicated one -- like filing mail into a dozen folders.
Think of it as a personal assistant for your inbox.
Since v0.21.0, POPFile supports multiple user with a single instance.
Using ${LOCALDIR}/sbin/popfile.sh, you can start your own POPFile
easily; it uses ${HOME}/.popfile as a working directory.
Note for old POPFile users: copy messages/ and corpus/ directory to your
${HOME}/.popfile directory (if not, create it), then start popfile.sh.
POPular is a suite of programs for setting up large POP3 server systems. It
consists of a POP3 proxy, a storage server and lots of utility programs. Note
that this program is intended to be used in large email systems and is
therefore quite complex to configure. If you only have a few thousand
mailboxes, you are probably better of with a different POP3 server.
'mailfmt' is a program to reformat mail and news to remove leading
quotation characters and wrap the lines to a reasonable width.
You need a reasonably current copy of Python to run the main script.
postfix-policyd-spf-perl is an RFC-4408-compliant SPF policy service for
postfix written in Perl.
Policyd-weight is (as the name says) a weighted policyd for Postfix.
It uses HELO, MAIL FROM and the MTA IP address for scoring their
correctness. It also uses definable DNSBLs and RHSBLs in a scored fashion.
The program uses the postfix policy delegation protocol to control access to
the mail system before a message has been accepted (please visit
http://www.postfix.org/SMTPD_POLICY_README.html for more information). It
allows you to choose an action (e.g. reject, dunno) for a combination of
several smtp parameters (like sender and recipient address, size or the
client's TLS fingerprint).
Postgrey is a program which implements greylisting and is
designed to work with the Postfix MTA.
PostSRSd provides the Sender Rewriting Scheme (SRS) via TCP-based lookup
tables for Postfix. SRS is needed if your mail server acts as forwarder.
