First of all, I'm using evolution as the client. I have no idea what you mean by mechs, but I guess I'm using whatever the Fedora Core default is, unless that is altered in /etc/mail, and I have no idea what 'saslauthd' is. I checked the dates on the files in /etc/mail against the dates in my backed up /etc/mail from the server PC and found that I had not extracted them over correctly. I have now fixed that. Now when I try to send mail from outside my domain to inside it, I get the mail returned from my domain's postmaster saying
Do not take it offending, but you should only run a mail server public reachable after you learned the basics.
If you would have a look at the original sendmail.mc file shipping with FC1 you would see:
dnl # PLAIN is the preferred plaintext authentication method and used by dnl # Mozilla Mail and Evolution, though Outlook Express and other MUAs do dnl # use LOGIN. Other mechanisms should be used if the connection is not dnl # guaranteed secure. dnl # dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
MECH means the mechanism SASL uses to handle authentification data (username and password). And the saslauthd is the SASL authentification daemon, run by the init script /etc/init.d/saslauthd.

You domain name is not listed in the /etc/mail/local-host-names files.
