Open-source Web-mail systems, mail filtering, delivering
messages to an IMAP Inbox tagged for deletion and other
interesting thingsRobin Whittle
This directory was revised in May 2008 to
remove a bunch of old things and concentrate on the following topics
related to mail servers:
- Suggestions on where to find
open-source web mail
- A mail server system based on
Postfix, Courier IMAPD and Courier Maildrop (mail filtering),
with Anomy Sanitizer to deal with attachments with executable
filenames and Spamassassin to deal with spam. I use a two-level
sorting system so the spam-marginal mailbox has fewer messages, but
the most likely place to find a false positive. The system is good for
lots of mailing list messages, which I sort and copy to their own
mailbox, and send to the Inbox, tagged for deletion. This means I
get to see all the mailing list messages in my Inbox, but can easily
expunge the Inbox to stop them cluttering the Inbox.
to the server-based
Courier Maildrop mail-filtering system to enable messages to be
delivered to the Inbox, tagged for deletion. (Great for mailing list
messages - see them all in the Inbox and then expunge to remove them,
but copies are already in their own separate mailing list mailboxes.
Also, how to configure Thunderbird etc. so the details of
messages tagged for deletion are not displayed in the index with a
strikethrough effect. This means they are perfectly readable, and
simply have a red cross next to them.)
little program "subjadd.c" to be used as part of a mail filtering
system to add things to the subject line of messages.
- How I
built a CentOS (free version of Red Hat) Linux server with software
RAID 1 hard drives, and a nifty backup arrangement for the hard drive
There are a few other low-key items:
I used to run a Web-Mail discussion list on
Yahoo Groups. However it never generated much discussion and I
will give it to anyone who wants to run such a discussion forum, which
I think would be most valuable. There are discussion lists for
each web-mail system, but not for people comparing notes and trying to
decide which one to choose.
Main contents in
(might be a how-to for you, dear reader) on my home-office mail server:
basic CentOS 5.1 system with RAID 1 dual redundant IDE hard drives.
Some potential modifications to kudzu so it keeps old
configuration details for Ethernet NICs even when a new NIC is found.
Various basic config things not related to email, such as Midnight
Commander, NFS etc.mta-integration-01/
Installing and integrating Postfix, Courier IMAPD, Courier Maildrop and
Notes on configuring
Thunderbird etc. such as to turn off format=flowed and to turn off the
use of strikethrough
when listing a message which has been tagged for deletion in an IMAP
mailbox. Also, how to configure Thunderbird so it sends plain
text messages, not HTML.
modifications to other people's software:
Modifications to Courier Maildrop so a message can be put in a
mailbox already tagged for deletion. Also, subjadd - a
program to add things to subject
lines of received emails in the server.
older pages of potential interest:
Old page for my perl script for converting mailboxes from mbox to
Old directories which exist with zipped
contents, but which are about software now probably not used much:
Postfix-SA-Anomy-Maildrop/ , RH71-Postfix-Courier-Maildrop-IMAP/
, RH90-Postfix-Courier-Maildrop-IMAP/ .
to find open-source web-mail systems?
I used to have a list of web-mail systems
here, but I was not able to keep it up-to-date. Here are some
suggestions on where to look.
There is a webmail page here: http://en.wikipedia.org/wiki/Webmail
finds slightly more "web-mail" pages than for "webmail".)
However, it doesn't lead to any lists of open-source web-mail
systems. That would be a fine project for a Wikipedia page.
To-do: add a link to the ISP-Planet webmail list.
Where to discuss administration of open-source
Please tell me of
any discussion lists etc. where this is discussed. I have a
dormant Yahoo Group "Web-Mail " for this purpose if anyone wants to run
such a list.
