[NTLUG:Discuss] Comcast outbound email server

[. Daniel]

I am a really stupid person sometimes.  Just wanted to say that first-thing 
so that no one else needs to remind me.  Sendmail config files make me 
dizzy to look at them.  But let me state what I want to happen and then I 
will hope that someone else here is already doing that and is willing to 
tell me how.

I run my own personal domain at home.  I connect using Comcast.  I receive 
email just fine but if I were to send outbound email from my IP address, 
much of the time it is blocked in some way because I am operating from a 
residential IP address.  So I need to send to a server that isn't blocked.  
My solution for now is to configure my client software to send to 
alternative outgoing email servers.  For now, I am using my domain 
registrar's outbound server which requires SMTP AUTH.  I can set that up on 
my clients just fine, but I'm lost in setting it up on sendmail.  Sendmail, 
as I mentioned before, invariably results in dizziness and nausea.  
(Doctors have recommended discontinuing use, but I have found other MTAs 
confusing to get set up... Sendmail, basically, just works... basically.)

So I'm hoping someone else has conquered this problem and wouldn't mind 
sharing with me?
