We are getting an odd error with our "Forgot Password" link.
A user alerted us of an issue he had. When he entered his email address it came up with the "Email sent" page, but the error below appeared up on the top of the page in a yellow box:
"Mail Error: mail(): SMTP server response: 550 Requested action not taken: mailbox unavailable or not local"
I tried the link with 2 different email accounts of mine, one being a yahoo account which was the same as the users, both worked fine and I recieved the emails. I am positive that his is a working email because he emailed us from it and he is receiving leads from our system (from a mail.php that is outside of CMS). He is currently an active user in our system as well.
The only thing that I saw that was different from "normal" was an underscore in his email address. Such as "first_last@yahoo.com". I have seen this more often lately but I don't know if this could be the issue or have anything to do with it, but wanted to give you as much info as possible.
Do you know of anything that would cause this to work for some emails but not others? And if so, how do we fix it?
Thanks!
