I upgraded Mime mail alpha2 to alpha3. I had installed SMTP Authentication module 6.x-1.0-beta4 before upgrading Mime mail module. When i upgraded to Mime mail alpha3, I was not able to send email through the SMTP module. Also, I couldn't send newsletter by Simplenews module. Even password reset function for users didn't work correctly. It sent out empty email with noname attachment without any extension.
I uninstalled the Mime alpha3 version and installed the previous version (i.e Mime mail 6.x - 1.0-alpha2). All problems resolved. I was able to send email by SMTP module. The Simplenews module could sends newsletter. The resent password function is working correctly now.
It seems there some problems in Mime mail 6.x-1.0 alpha3. Also, It doesn't work with SMTP Authentication 6.x-1.0-beta4.
