Well, maybe it doesn't do any harm to 8-bit characters, but it doesn't understand EHLO command, and therefore cannot advertise itself to be 8-bit compliant... AFAIR standard SMTP doesn't include 8BITMIME... The mail exchangers, seing that, auto-convert the mail to quoted-printable - here's an exerpt of my header: Content-Type: text/plain; charset=ISO-8859-2 Content-Transfer-Encoding: quoted-printable X-MIME-Autoconverted: from 8bit to quoted-printable by mr2.ipartners.pl id fACF4Tx02947 > Would you please send examples to [EMAIL PROTECTED]?

To my understanding it's not a problem of SMTPD screwing anything up, it's just that it can't say "8-bit's OK with me" :) But if you see it otherwise I'll prepare a set of such converted message examples and send it. > > I was wondering whether you Guys have any contact with Obtuse's developers > > and know anything about their plans to change it? > I am currently the maintainer of the Obtuse SMTPD RPM and have take on > de-facto maintenance of the code as well.

Wow :) SMTPD seems to make the job of relay-securing a mail server easier, but it's being used as a front-end, so from the outside many advanced features of the "real" MTA might be invisible...
