Mailers - Mail User Agents (MUAs) HomePages

Latest changes on 2003-12-07

75 entries listed - 47 entries to add

This page shows a list of "Mailers" (techspeak: Mailer User Agents - aka MUAs) and their homepages on the web. Some other mail related programs are listed, too, though. The basic idea is to give minimal reference to these programs by listing their homepage (and maybe an alternate address such as a mirror) and their latest stable and beta releases with their release dates. and hopefully being up-to-date, too.

The table also shows how these mailers identify in the mail header. the standard line so far has been "X-Mailer:", but it should now be changed to "User-Agent:". You are welcome to send me identification lines for those which have none listed yet or updates to those already listed.

I find that hunting for release infos to commercial programs is often a drag so if these info are not presented well on the main site then just don't feel like wasting my time with this and promoting their latest version. So if anyone wants to send me the latest versions and identification strings for Mozilla, Outlook, and Outlook Express then you are certainly welcome.

Found a bug? Is there an update necessary? Please send me an email! Thanks! :-)

i wish people would give their products *short* addresses.  example:

    Misc Thoughts

    HomePage A good program (especially mailers )should have its own homepage - complete with info about all released versions and release dates. And every good program should have its own domain name.

    several free programs are hosted by some site like (eg aethera, anubis, mahogany, sylpheed-claws), but some are simply subjected to the name of the company which maintains it (4dmail, albert, execmail, mulberry, the_bat, xcmail). they are simply regarded as "projects" within a company so their homepage gets a subaddress for that company's website. i wonder why this has to be when every page shows the company name+logo, anyway. rather than giving it some extra directory on the webserver where the domain name of the company comes first, i'd suggest to add an alias hostname like with "".

    TkRat does not identify with any X-Mailer header "Because I [the maintainer] haven't felt that it is important enough to spend the time needed to implement it." * well, Spamassassin gives bonus points for mailers which are known to be used by sensible people. So - no bonus points for TkRat there.
