  Hmm. the NAT/SNAT is working fine, when I recive the SMTP answer
(LOG on PREROUTING and INPUT of filter, nat and mangle) the packet
arrives with the correct ip on dst addr. But I can only see it, on
mangle PREROUTING, but can't on other hooks. I don't know if it is
related with some sanity check or checksum....

  That's another doubt, dos nat PREROUTING called with syn+ack
packets, or only with sym packets?

  I have these modules loaded:
ipt_LOG                 5760  7 
ipt_mark                1792  0

Ok, I used to use MUA that shows-me the text/plain attachments as the
e-mail body (like mutt). But now I see it won't happen all the time.
My mistake, sorry.
