Your description is very unclear. What is a "huge amount of mail"? a) one very large message b) a large number of small messages - specify how many What does "incoming connection limit" mean? a) a slow connection to the Internet at the client site b) a limit to the number of concurrent SMTP sessions for receiving mail at the client site c) something else - describe in detail If you said 1-b and 2-b, and your client is using Exchange and doesn't know how to change the incoming connection limit, we need the version of Exchange in order to advise you on how to advise your client. BTW the default incoming connection limits for Exchange are fairly high.

It takes ages because of incoming mail connection limit. Is there a way to get around this problem? Short explanation.... The mails get send to the exchange server from an application server which generates the electronic payslips who then routes it to the different domains. But because of the incoming connection limit takes hours to get to the clients Any suggestions? Thanks Andre
