ETH-Sys with 'authenticating' mailer ?

My ISP suddently requires 'authentication' of all external
[to the domain] email sends. And tells me how to setup
Micro$loth-outsp00k !

Since I've been using ETH-S3 for several years, I have no intention
of using the garbage that posts line-terminators as "=" & "=" as '3D'
...etc.

I've got linux installed: Slak 3.3, RH6.2, Mandrk9, FC1.
What mailer could do mail-Tx with authentication - ie.
avoid error 517 ?

PS. I confirmed that Micro$loth-outsp00k can be set to do it.

Thanks for any info.

Best would be to configure your own sendmail according to
http://sendmail.org/~ca/email/auth.html#AUTH (see "Using sendmail as a
client with AUTH" section and "Misc.") and direct your familiar MUA client
to submit your mail to your own MTA, which will provide the necessary auth
and transport to the ISP's MTA server.

If you insist on a new client that provides AUTH directly to the ISP's
server then you can select from among
