We can send mails across the network from 1 server to another via a centralized smtp server. However, the we get a synchronization error on the server randomly.
So for example if we send a simple mail 6 times the 3rd one fails with a synchronization error. When we look at the network packet we have
RCPT TO: email@example.com
C:QUIT -- This for some reason is called before the smtp server processes the request.
Any clues why this with happen.
