Hi,
Is anyone can explain why the ESA blocked the outgoing email to gmail? I cannot migrate from old Email Gateway to ESA due to this issue.
Here's my setup
1. Only outgoing email for testing, incoming still on existing Email GW.
2. Outgoing: Email Server -> ESA (DMZ) -> Public
My testing is from ESA CLI
ironport.xxx.com> telnet x.x.x.x 25
Trying x.x.x.x...
Connected to x.x.x.x.
Escape character is '^]'.
220 ironport.x.com ESMTP
helo x.x.x.x
250 ironport.x.com
mail from:test@x.com
250 sender <test@x.com> ok
rcpt to:test@y.com
550 #5.1.0 Address rejected.
Appreciate your help!
