SMTP traffic rejected from

[Mike_Sab]

We are on CheckPoint R77.30 (please do not ask about upgrade, we are in process of demising these firewalls) and have a SMTP rule created in 'Security' and 'Application' yet the smtp traffic is denied. What is happening?

Connectivity between gateway and the smtp server is fine, I can telnet in port 25.

Why is this happening?

Which one of the rules you are showing is rule 39? Also, would it be possible that you still have your old SMTP server in the rule 39 and SMTP proxy config?

Even though the old smtp exists, I added explicit rule for this src and dst, same error.

I can confirm the SMTP proxy config reflects the new smtp servers.

Its' strange, I made some minor changes (added new SMTP server to old SMTP rule), this doesn't get invoked but a rule for source subnet. The rule is 

Source: 192.168.10.0

Dst: any

Services: Any

Action:  Accept

The smtp traffic hits this rule and STILL it is dropped. It is complaining about "Failed to connect to SMTP server", I am out of ideas.

Hey Mike,

Send me a message offline, lets do remote session when convenient, we can try figure this out if the issue is still ongoing. Sounds like somethin simple might be missing.
