[gentoo-user] [OT] Sendmail and Comcast

[Mick]

Hi All,

If any of you guys has a working sendmail configuration with Comcast I would 
be grateful if you could share off list.  Although I have followed the 
instructions detailed here (except for the masquerade options) I cannot get 
it to work:

After a long day trying to get it to run I have now grown blind to it.  The 
error I get is:

... while talking to smtp.comcast.net:
>>> MAIL From:<nagios@my_domain.com> SIZE=578
<<< 550 5.1.0 Authentication required
554 5.0.0 Service unavailable
