I used to just send my mail directly but finally switched to using a relay service -- in my case DynDNS though there 
are others like TZO. I had to when running a dual WAN because Comcast and Verizon only accept connections from their 
addresses and with a Dual WAN you don't want to be tied to one or another.  In effect they are also vouching for me so 
that AOL will deign to accept my email.

Turns out to have added bonuses because I can connect from anywhere without changing my settings. They support 
alternate ports encrypted connections.

Note that Microsoft dropped the SMTP server from Vista – though sometimes I do want to run one so I do it in a virtual 
machine. Note that Verizon blocks port 80 inbound but not port 25.

The policies seem to be arbitrary and often perverse responses to larger issues. Too bad we don’t have a better 
relationship identifier than today’s email address but that’s another topic.

Comcast's customers have a worse problem in 2008 -- some can't get email.



SF bay area comcast is having large, yet unsolved email problems since

start 2008. According to the error message I saw in one such bounce case

(copy available by request), email to at least some of their customers'

comcast

address is being blocked before reaching comcast because comcast's IP

pool is now in spam black-lists.



So, their sudden blocking of port 25 seems to be a quick, ugly

measure to try to get their IPs off spam lists, so their clients may

at least receive email again.



Of course, other solutions exist but comcast, that was not very proactive

before when the problem started even before 2007, may just stick with

the ugly solution...until it also fails.



Cheers,

Ed Gerck
