Read the error message. Your email gets to the mailserver, but it did
not accept it! No netfilter issue!

Did you load the inspection modules for ftp? ip_conntrack_ftp,
ip_nat_ftp?
Correct me if I am wrong, but your iptables script does not filter
anything, does it? Therefore you essentially do not have a firewall at
the moment which could block anything, do you?
Your Policy is ACCEPT and you do not have any DROP rules, only one NAT
rule.
Cheers,
Ralf
