[Dovecot] I can receive but not send

[Dennis Clarke]

I'm not too sure where to look here. I can access my mail via Dovecot and
there is an initial requirement to accept an SSL key ( self signed )
however after I look in my inbox and read a piece of email ( via SeaMonkey
eMail client ) I can not send. I simply get told that the server would not
accept the smtp connection. I was hoping for a smtps connection but I'll
take what I can get.

Am I missing something obvious here ?
