XF 2.2 New Email Throttling Error Message

[Sal Collaziano]

Is this something new with XF 2.2?

• Swift_TransportException: Email to email@email.com failed: Expected response code 250 but got code "454", with message "454 Throttling failure: Maximum SigV2 SMTP sending rate exceeded. "

I'm receiving this on various installations and I've never seen it until recently...

It's related to your SMP server.

XF just reports email related errors for discoverability.
