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
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?
