Gmail SMTP problem

Postby rphnunes » Fri Jul 03, 2020 2:57 pm

Hello,

I haven't been able to send emails in gmail for a few months using zimbra as the sender. It accuses error and I already tried all ports, I contacted google and they sent me to check the zimbra SMTP. But so far I haven't been able to solve it, could you help me?

I have this message "Couldn't reach server. Please double-check the server and port number."

if that SMTP server name is correct then it would appear to have no DNS records:

Code: Select all

The message appears to be telling you to send mail through this server:
