need help with sendmail configuration

[mrwhitee]

---

I set this up months ago and had all kinds of problems and then finally got it working good enough to where I could send and receive emails from outlook but some of the scripts in my websites have trouble sending mail.

I often get Deferred: Invalid argument, and host map: lookup (srv): deferred and some others I think but thats all I have in there at the moment.

cant seem to post sendmail config as its complaining about not having enough posts to add links.

Here is my sendmail config

Here are a couple of log entry I get when trying to flush a single email: I changed the user email and my server domain
