That having been said, I would next do the tcpdump on eth0 on the bridge
(make sure the SYN,ACKs are being sent from the bridge) then on eth1 on the
outer firewall.

I see this conntrack entry on the bridge:

tcp      6 35 SYN_RECV src=194.179.55.129 dst=10.215.144.7 sport=61911
dport=25 packets=1 bytes=52 src=10.215.144.7 dst=194.179.55.129 sport=25
dport=61911 packets=5 bytes=260 mark=0 use=1

This indicates that Netfilter connection tracking on the bridge is not
seeing or not recognizing the SYN,ACK response.
