[GRLUG] Getting a straight connection from Comcast

Another option is what I do - get a basic VPS somewhere that has
full/open Internet connectivity.

You could also get just the most basic of one, and then either use it
as a relay (use SMTP auth to connect to it) OR set up a VPN link from
your home server so that it has access to the full outside

I would hate to have to use the outbound mail relay of an entity such
as AT&T or Comcast.

They require an SSL connection (port 993), require you to authenticate to use it, and finally also require you to whitelist additional email addresses you will be sending mail from (e.g. matt at zigg.com.)  But yes, I’m not delivering directly.
