Hi
Do you guys know how to fix this error
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<test.test.com #5.5.0 smtp;553 Requested action not taken: mailbox name not allowed or chunk too large>
I can't find anything to resolve this issue I found something about special characters in a e-mail address but that's not it. PLEASE HELP
