I've got an ISP that blocks port 25 incoming, so that I can't easily run a mail server, however the dynamic SMTP here allowed me to accept the incoming email on a different port, but now I've got a different problem. Now that AOL is blocking email servers from dynamic IPs, I need to use ChangeIP's SMTP server as a relay. First, some background:

I have a domain, let's say example.net. It's hosted here, and I also have a subdomain mail.example.net that points to example.net's ip as well. I have example.net set up as a Dynamic SMTP so that all email coming in for [email]username@example.net[/email] gets sent to a port other than 25, so that I can use my machine as an email server. That much is working properly. I also got a normal POP3 domain for mail.example.net, and set up a mailbox [email]sendmail@mail.example.net[/email] and gave it a password. Therefore, I assume that with the authenticated SMTP I need to set it up to authenticate using username [email]sendmail@mail.example.net[/email] and the password I set for sendmail, and then the relay will work. How I want it to work:

A user on my system picks up his email via POP and then sends off his mail to my sendmail (which I need to work on how it'll accept relaying from my users, but that's a seperate issue altogether). My sendmail server accepts the mail as valid, and then immediately connects to smtp.changeip.com, authenticates, and transfers the email, and ChangeIP's server sends it wherever it needs to go. The last step is what I'm asking for help for

Thanks in advance,

Check out this link:

[url]http://www.sendmail.org/~ca/email/auth.html[/url]

In that page there is a configuration section... readup on this item:

DefaultAuthInfo (confDEF_AUTH_INFO)
specifies a file in which the authorization identity, the authentication identity, the secret, and the realm to be used for authentication are stored. This file must be in a safe directory and unreadable by everyone except root (or TrustedUser). Example: [b]It is used when sendmail acts as a client to authenticate itself to a server. [/b]

Thanks, that line you pointed out to me was the last missing piece (I already had the other two uncommented out and was using your smtp server as a SMART_HOST).

You guys rock!
