TCP Connection timeout

Hi, we used pfsense since long time ago without any issue.
We are currently having some issue with outgoing (internal -> wan) tcp connection (smtp) timeout.
The pfsence box (an esxi vm) is configured as a transparent bridge with a rule which allow traffic from the internal host to anywhere using any protocol (using a customized gateway, cause there are two ip network on the same physical).
On the server behind pfsense the most (almost all) outgoing connection connection hang like this (netstat output):
tcp 0 443 xxx.xxx.125.18:58451 18.104.22.168:25 ESTABLISHED
tcp 0 1185 xxx.xxx.125.18:46163 22.214.171.124:25 ESTABLISHED
tcp 0 3442 xxx.xxx.125.18:58348 126.96.36.199:25 ESTABLISHED
I've already checked the state table which is quite empty 605/15000. Where's the problem ? Any hint ?
Note: if I remove the firewall in between all work flowless.
