Using DNN 7.3.4, have configured and tested the outgoing (SMTP) capabilities of both Admin and Host without any errors. The SMTP authentication is set to Basic. BTW - when I tested with anonymous authentication the test emails went through alright.
Dispatched a testing newsletter to numerous e-mail addresses without any error, too.
But when it came to editing a profile of a registered user or upon changing his password instead of a notification email message came the errors like below:

Does anyone around here know how to tackle this issue?
The SMTP is already set, there were no problems when testing the outgoing mail on Admin or HostSettings.
I'm getting tired.
