Hi

One of our customer has a VPN from his home office (wrap+m0n0 ver 1.22) 
to his office (wrap+m0n0 ver 1.22), that works fine. When he tries to 
send a mail from home over the VPN to the postfix server then the mail 
is never delivered to the mailserver.
I noticed that small plaintext messages can be delivered to the postfix 
server but if the mail gets bigger then only the first part of the data 
are sent.
On the mailserver i started tcpdump and could see that the mail could 
not be sent because there are a lot of bad tcp cksum messages.
So the mailserver gets the first part right and the rest of the data are 
bad. How could that happend?

regards

Andreas
