CiviCRM Community Forums (archive)

I've searched through the forums and tried everything suggested.
I'm sure my SMTP settings are correct, I am able to test them in an email client and they work fine. I've added the password to the settings file. But I still get this error when customized profile is submitted and should send info-mail about new subscription to admin.
(My host uses port 587 + authentication)

Sorry. A non-recoverable error has occurred.
Return to home page.
