[cobalt-users] POP Before SMTP Broken

["Santiago Montalvan" <smontalvan@xxxxxxxxxxxxxxxxx>]

Yesterday I installed SolarSpeed's Qube3 Sendmail patch and it seems that my
POP before SMTP is broken :(.  It does not affect me a lot because I am the
only one who uses POP3 outside the company to check and send e-mails
(everyone else uses Webmail) but I would like to fix this.  I keep getting
these messages:

The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was 'email@xxxxxxxxx'. Subject
'Thanks!', Account: 'brattain', Server: 'mail.brattain.com', Protocol: SMTP,
Server Response: '550 5.7.1 <email@xxxxxxxxx>... Relaying denied.  Please
check your mail first or restart your mail session.', Port: 25, Secure(SSL):
No, Server Error: 550, Error Number: 0x800CCC79

What can I look into to see if I can fix this?

Thanks!

Santiago.
