Problem in integration of fortimail in fortimail

[Mohamed_Abdelmoteleb]

Good evening

I have a problem in adding fortimail in fortigate  After I entered the ip address ,username, and password which I use to authenticate fortimail the red alarm shows "unable to connect" How can I solve this problem?

You need to enable the REST API feature in the FortiMail first. Goto the FortiMail CLI and enter the following commands:

config system global

set rest-api enable

end

You should now be able to add it to the FortiGate.

I tried the above method but the problem exists

the error : Failed to connect still appears

Did you  do a any "diag sniffer packet <interface> 'host x.x.x.x'" and look for any 3way tcp session? You can also dump from either end ( FGT or FML )

Does the login here means the username or other thing

[neonbit]

Yes this is IP, username and password for the FortiMail.

After a long time troubleshooting  we find the cause of the problem when we configured fortimail we changed the default HTTPS port number 443 to other custom port  so fortigate is set to listen to port 443 not other port  so when we set it back to 443 It works Thanks all for your kind support.
