Linux SMTP/relay question.
I recently switched from my Trusty DSL fixed IP connection to a faster 4mb/s cable dynamic IP connection.
As you all know, most of the IP's fetched with DHCP are blacklisted. That understood, most mails bounces due to blacklisting.
My question:
Is it possible to forward mails to a clean smtp/relay to avoid this?
Does such a service exist?
I dont want to spend the extra $30/month for a static IP. DHCP works great except for the blacklisted IP's Comcast dishes up.
Any suggestion to get a more affordable solution?

Do comcast not have their own mail server you can use as a relay?

Yes they have, but how do I forward my smtp (localhost) to their smtp ?
You need to setup a smarthost. I would be able to give you more information but you never mentioned what MTA you used. I use exim4 as an MTA and use the following to route all of my mail to my ISP's smtp servers.
# Send all mail to a smarthost
smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* mail.myisp.net bydns_a"
# Send all mail to a smarthost
smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* mail.myisp.net bydns_a"

Ok, so you mean there is a way to configure Linux to forward to comcast's smtp.
That would be great.
Please fire away.
At the moment it just goes out smtp via localhost.
How do I set up smarthost?
As this question now deserves more points I raise it to 280 and give you a chance to solve it.

I forgot to say, I obviously use sendmail. If sendmail can be configured and I dont have to install replacements it would be nice. If not, then ok there goes sendmail. I am generally quite happy with sendmail
I don't use sendmail but from what I gather you need to have a line in your config something like:
define(`SMART_HOST', `smarthostIP')
define(`SMART_HOST', `smarthostIP')

Sounds easy enough, I'll go read up some mopre and try.

I looked in /etc/mail/sendmail.cf and there is only smarthost code in the script boody and nothing in the headers of the script.
I am not sure what I have to add.
Is it what zuralin said?
smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* mail.myisp.net bydns_a"

Thanks guys, works like a charm.
Hope the split is ok.
My mail headers when routed now shows comcast.net as my smtp.
So now I am rid of having to use my own dynamic ips and saved $30/per month.

the best solution is communicate with the black list owned and tell to remove from them.
i have the same problem 2 years ago. and the best solution was communicate my problem...
