SMTP settings for sending email?

I know there have been several posts about sending emails via
ActionMailer, so I’m not trying to add to them. I understand the
process of sending emails on the RoR side of things, but I have no real
knowledge of SMTP settings. When I configure my “environment.rb” file,
I don’t know what information to input. I understand the port number,
user_name, password, and authentication terms, but I’m confused on the
address and domain. Is there a website that explains what the address
and domain are for people who don’t already have a basic understanding
of it? Any help would be appreciated.

Well address is the email address that you want the email to come on…

say ur email address is removed_e[email protected] then thats ur address and the domian

hope this helps for understanding…
