I noticed recently that all the sites I have upgraded to the latest version suffer from the same problem.
I send out emails from forms and since the upgrade that has become a problem with me getting the following errors reported:
Mailbox unavailable. The server response was: 5.7.1 <[email protected]>... we do not relay
I have removed the full email address.
I have changed nothing since the upgrade; I am using the same SMTP server at dnn4less with the host email, and the same SMTP username. They then changed the password and it did then work but not the following day.
Is something resetting the SMTP server password?
