[mail] Failed to send email: 553 5.1.2 The address specified is not a valid RFC-5321 address. ***************.** - gsmtp

This problem surfaced recently. I did some googling and found this thread, where a google employee responds:

in the past week we've rolled out a change which enforced validation of the MAIL FROM argument to be a valid RFC 5321 email address.
