3CX SMTP Server blocking emails

[netech]

How do I check / remove a blacklisted email address on the 3CX SMTP servers which is not allowing voicemails from being sent, If I change the customer email address to my email address the voicemails get forwarded.

If using the 3CX SMTP and an email bounces, the address is blocked for 7 days. It gets auto-added/auto-removed.

Easiest is to make an alias for that user and have it set in 3CX if you can't wait the 7 days. Or open a ticket with support.

Hi, we are having the exact same issue when sending via SMTP relay. Seems to have stopped working over the last week, the SMTP test works, missed calls/voicemail emails work so stumped on this one.
