First of All, I loved the new version, over all layout is so much better...
I recently have updated from 6.5.0.f to 7.0.0.b due to requirement of higher php version, there were some issues, which took me some time to fix, and now only one point is left. Qmail is not sending emails out.
So I can receive email on my server
If I send email from same account to it self, the title is changed to ****SPAM****
If I send email to gmail, email never reach there, but in the mail log, i can see email sent success message
Thanks a lot
