Dialback works by the sending server giving the receiving server a key. The receiving server does a DNS lookup and contacts the returned IP address. Then the key is verified. If the verification if succsessful, the receiving server tells the sending server it's ok to proceed. While trying to figure out the internals I noticed that the process seems to start again in the middle when the receiving server contacts the looked up IP to verify the key. This contact marks the beginning of a dialback connection where the sending server becomes a receiving server. It all got very confusing trying to look at all the packets in the log file and trace it by hand.
From the error message, I would say it is definitely a dialback issue, and it is probably the server on the other end not being able to verify the server behind the NAT. Run the server in debug mode and capture the output ( jabberd .... -D > debug.log 2>&1). Then look for entries in dialback*.c matthew c. mead wrote: > Anybody? > > Anyone familiar with how dial back works?
