Resolved Unable to send notifications email

[Veno0om]

Hey,

My server is not sending any notification mail and even so same with WHMCS and WordPress can't send email or it's showing that email is gone but in fact not received with informed that i'm using Google gsuite from Plesk, do you think shall remove / install extension.

Regards,

The issue is solved by allowing port 25 in firewall rules.
