failure when receiving data from the peer

[Osawe]

Hello All,

I have been receiving notifications from zabbix using M365 smtp but suddenly it started failing and when I test media I get the error "failure when receiving data from the peer".

How do I resolve this as we have not been receiving notifications on downtime since it started.

Regards.

Guys, I'm encountering the following error. When I send the email via command, the email is sent normally. However, if I send it through the web interface, I get the error 'Failure when receiving data from the peer'.

Below is how my environment is set up. Do you know what could be the issue? The Zabbix version is 6.4.18. The command that works is: curl -v --url smtp://smtp.mailersend.net:587 --user 'userassword' --ssl-reqd --mail-from '[email protected]' --mail-rcpt '[email protected]' --upload-file mail.txt.
