Hi,

After replacing my firewall with a M0n0wall, I noticed errors in
/var/maillog regarding a protocol used by Spamassin: DCC. It's used here
for exchanging checksums of spam.

Apparently, the DCC protocol has the same problem as active FTP, when
going through NAT: it requires some support in the firewall, like a
module or a proxy.

Which nat-unfriendly protocol does the M0n0wall support? Is there a way
of telling him about DCC maybe?
