SMTP Relays are also called Smart Hosts... but nobody knows that!
This is regarding document https:--support.cpanel.net-hc-en-us-articles-360052412573-How-to-Set-a-Third-Party-Smarthost?source=search&auth_token=eyJhbGciOiJIUzI1NiJ9.eyJhY2NvdW50X2lkIjo5Mjc3OTc5LCJ1c2VyX2lkIjoxNTAzMjE1NzE5ODgyLCJ0aWNrZXRfaWQiOjk0MzEzNDkwLCJjaGFubmVsX2lkIjo2MywidHlwZSI6IlNFQVJDSCIsImV4cCI6MTYyMDMxNjQxNX0.pB0WHpsSpRwDntEm1Rk65_zuBo2buWvTRjFr437ozm8
After a long search as to why my brand new VPS server at GoDaddy would not send email, I discovered that they block port 25... as most providers do. I found out that I can use their SMTP Relay server and they gave me the address but could not tell me where to enter it into WHM.
A search of the cPanel Forums and Docs did not turn up the required secret but Anthony May, my support tech, pointed me to this document and I was able to enter the data in about 10 seconds!
I was searching for "SMTP Relay" which could not be found.
Could we possibly add the following phrases to this document.... .... "SMTP Relay", "SMTP Relays", "Port 25 Blocked" "Why can't I send email" "External SMTP Hosts", etc?
