I have problems with support email and changing the default email of the website to email@example.com (I don't receive the confirmation link at firstname.lastname@example.org though if I change to email@example.com or other non domain address it works.
The mass mailer will send email from the support address
I added the line of code as suggested in this thread
and now I get the error message
Cannot connect to Gmail: Too many login failures
(My domain is set up to use Gmail.)
Does this error suggest I should wait a while before trying again?
