qmailanalog is a collection of tools to help you analyze qmail-send's
activity record. It supplies statistics to answer a wide variety of
questions:
* overall: how many messages? recipients? attempts? etc.
* ddist: how soon were 50% of the messages delivered? 90%? 95%? 99%?
* rxdelay: what's the best order of recipients for mailing lists?
* recipients, rhosts: who's getting mail? bytes? messages? attempts?
* successes, failures, deferrals: why? how often? how much delay?
* senders, suids: messages? bytes? load? recipients? attempts? delay?
qmailanalog also includes several tools to focus attention on particular
senders, recipients, or messages.
qmqtool is a qmail queue manipulation program geared towards the
viewing and safe modification of the contents in a qmail queue.
Features include finding abusers, sorting messages by sender/sender's IP,
showing stats, requeue messages, queue consistency check, queue
backup/restore, and others.
the popa3d goals
================
Is a POP3 daemon by Solar Designer.
Well, the goals themselves are obvious; they're probably the same for most
other POP3 servers as well. It's their priority that differs. For popa3d,
the goals are:
1. Security (to the extent that is possible with POP3 at all, of course).
2. Reliability (again, as limited by the mailbox format and the protocol).
3. RFC compliance (slightly relaxed to work with real-world POP3 clients).
4. Performance (limited by the more important goals, above).
This port is installed to be run from inetd, which is sufficient
for normal usage. However, it is possible to build a stand-alone
version, should you need better performance.
maildrop is a replacement for your local mail delivery agent,
similar to mail/procmail.
- maildrop reads a mail message from standard input,
then delivers the message to your mailbox.
- maildrop will optionally read instructions from a file,
which describes how to filter incoming mail.
Instructions can be provided having mail delivered to
alternate mailboxes, or forwarded somewhere else.
Unlike procmail, maildrop uses a structured filtering language.
- maildrop knows how to deliver mail to mbox-style mailboxes and maildirs.
- maildrop is written in C++, and handles resources more efficiently.
maildrop can be used with sendmail, qmail, and other MTAs.
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.
relaydb is a mail header analyzer that builds a database of IP addresses either
known as legitimate senders or spammers.
relaydb doesn't itself classify mails as legitimate or spam, that decision needs
to be reached through other means. Neither does relaydb block spam itself. It
merely provides a list of IP addresses to block through other means.
cyruslib is wrapped interface for imaplib.py, it adds support for
cyrus specific commands. Function naming is the same of cyradm
This is a python extension module to enable python scripts to attach to
sendmail's libmilter functionality. Additional python modules provide for
navigating and modifying MIME parts, and sending DSNs or doing CBVs.
A few programs to allow qmail to authenticate users through a Microsoft
Active Directory.
SpamControl is a collection of patches for qmail developed and maintained
by Erwin Hoffmann (feh@fehcom.de).
Some SpamControl features: smtp-auth (plain, login and cram-md5),
requirement of brackets on addresses, qmail-queue, bigtodo, moreipme,
recipients, STARTTLS...
