zeMail is a minimalist webmail package written in Mason. It implements the basic features one would expect from an IMAP mail client, displaying folder and message contents, handling attachments and allowing you to move, mark and purge your messages.
zeMail package is written in plain HTML, and uses JavaScript only to reduce the click count, it will work perfectly with scripting disabled. Compared to the modern AJAX trend, this web mail package is designed to work everywhere.
Installation:
Download and unpack the tarball. Copy the directory lib/Zentus into your Perl inc. path (/usr/local/lib/perl/5.8.4 on Debian).
Copy the contents of mason/ into the desired subdirectory of your Apache htdocs directory or virtual host. Then add the following to your httpd.conf:
PerlModule Zentus::Mail::Connection
PerlModule Zentus::Mail::AttachmentHandler
PerlModule HTML::Mason::ApacheHandler
PerlModule Apache::Session::File
PerlModule Text::Autoformat
< Location / >
SetHandler perl-script
PerlHandler HTML::Mason::ApacheHandler
DirectoryIndex folder
< /Location >
< Location /attachment >
SetHandler perl-script
PerlHandler Zentus::Mail::AttachmentHandler
< /Location >
< LocationMatch "(/icons|/images|.ico|.html|.txt)" >
SetHandler default-handler
< /Location >
< LocationMatch "(autohandler|dhandler|.inc)" >
SetHandler None
< /Location >
This code segment can be added as-is if you intend to devote a VirtualHost to zeMail, otherwise prefix a directory name in the < Location > and < LocationMatch > tags.
Now install the necessary Perl modules from CPAN:
cpan -i HTML::Mason # or deb: libhtml-mason-perl
cpan -i Apache::Session # or deb: libapache-session-perl
cpan -i DB_File::Lock # or deb: libdb-file-lock-perl
cpan -i Text::Autoformat # or deb: libtext-autoformat-perl
cpan -i HTML::FormatText # or deb: libhtml-format-perl
cpan -i Net::IMAP::Simple # (needed really in name only,
# to be removed in next release)
You may have to create the temporary directory manually:
mkdir /tmp/zemail
chown www /tmp/zemail
Now restart your Apache and your are good to go.
Enhancements:
- Supports all basic forms of email, strips out MIME, displays attached images inline, and lets you download the rest.

DisSent (short for "Distribute Sent Mails") is a program for separating your sent mail from a single folder into different folders based on properties of the individual messages in the folder.
DisSent scans your mail storage and proposes a set of actions to tidy up your sent mail folders.
Almost all mail user agents (MUA, "mail clients") Ive encountered implement a standard way of handling outgoing messages by placing a copy of every sent message into a certain special folder.
While this might be a fail-safe approach, it is not very useful for you if you belong to those people who work with mail folders and rules to sort incoming mails. Usually, youll have your rules setup so that an incoming mail from John Doe will be moved into a separate folder, lets say "INBOX.Friends.JDoe". Now if you reply to this mail, your answer is moved to an entirely different folder, and if you want to look up your answer some time later, youll have to browse through all the mails you sent in the meantime. This is ugly.
Enters DisSent (short for "Distribute Sent Mails"). DisSent scans your mail storage and proposes a set of actions to tidy up your sent mail folders. More precisely, it gives you a list of messages along with proposals on where to move these messages. You can then select the mails you want to move and let DisSent do the actual work.
Known Issues
- The progress monitors should be modal so you cant execute other actions while DisSent is busy.
- The protocol SMTP in the login window doesnt really make sense.
