Any 3CX SMTP issues today?

[PTG]

Hi,

Are there any issues regarding 3CX SMT today? My server is unable to send any welcome e-mails, etc. Testing SMTP in PBX says "5.7.0 Denied".
PBX is on dynamic IP, checked FQDN in management console with google DNS and all seems normal, i.e. resolves to correct IP. Only have 1 public IP
Firewall on edge router is configured as a statefull firewall, so any connections going out should be allowed in. Testing firewall from 3CX PBX shows all green.
Could successfully refresh license
PBX is V18 update 4 (Build 965)

Anything else I can check?

Regards,
Francois

@PTG we dont have any issues on this.
Can you PM me with the key that has the issue and the email address where you try to send the email to ?

@PTG after our private conversation and as we discussed, the requests were coming from a different public ip and not from the one where the FQDN was bound to.
Now after the restart of the services of the PBX, as you confirmed all are smooth !!

Yes, sounds like a DNS replication issue your side, but all is good again, thank you for prompt assistance
