Howdy.

My client has a 3CX hosted system with Enterprise licensing. The sales offices are located here in US, but the email server was in Ukraine and was moved over this last week. Since Saturday I have not been getting 3CX system emails, like user invites, reports, and most importantly, a recorded web meeting on Wed.

The sysadmin offered the following diag;

"Yes, we see that letters from the smtp.3cx.net domain were constantly coming to you and XXXX until the morning of February 27, 2022. Since then, no letters from this domain have been received by our server. Thus, the problem is most likely on the side of 3cx.net. Perhaps this is due to the fact that one of our mail servers is still working in Ukraine and communication with it may be lost from time to time. Sometimes senders (mailing services) can block sending to email after several unsuccessful attempts to send. This situation has already occurred several times, for example, with the figma.com service, and only figma technical support could solve this problem."

The FQDN is xxxxx.my3cx.us and the email domain is xxxx.com

Can you see if something is keeping the system from sending messages, and can I get the link to download the meeting from Wednesday?

Thank you.
 
Hi @Mermonkey,

can you please PM me with your Subscription to check this further ?

Edit: I have checked our SMTP server and it seems that the issue is not on our side as the server received Connection reset by peer .

How do I PM you? I tried to start a conversation with you, but it said I did not have permission
 
Please check the report that our SMTP received while trying to deliver the email:
