CMS Made Simple Forums

I created site on our test server, it worked fine. Then I move everything to other server, which is identical to test server, just change user, password and added new domain. I think I changed every link, password and internal path in database and main config.php. All site is working fine exept that emails are not going out. I wrote a simple php application to test mail server on that server - it sending emails, so problem is not about mail server, it's somewhere in CMSMailer or its preferences. Thanks for any ideas what's wrong?

CMS 1.0.4, CMSMailer 1.73.10

YES, i found a problem. Somehow smtp mode was not working, changed to sendmail and it goes perfectly now!
