Re: transition from pop3 to smtp ??? advice needed


In regards to ports, for this specific topic yes port 25 is all you're
concerned with. But in regards to email overall you have 25, 110 (if
any clients using POP3 to connect), 80 and 443 to cover the bases on
RPC over HTTP. (as well as IMAP port if you happen to use it).

In regards to reverse DNS, this doesn't have anything to do with your
web host or your regular DNS (nor do most of the other items other than
your regular DNS entries if that's who you are using to manage your
DNS). Your DSL provider is who does that. You'll need to ask them.
If they won't set up a reverse dns entry for you then you can still
work, but will need to set a 'smarthost' when configuring Exchange that
uses your existing ISP's smtp server to route your email for you.

Sorry there are so many variables here that telling you 'the' answer
isn't really possible until all the blanks are filled in.
