Suggest you telnet to your server on port 25 and create a message in
SMTP and watch the results (an alternative - probably better way - is to
run "exim -d -bh ip-address-you-would-connect-from" when you will see
additional information on whats happening).

      * If there is an initial delay then you are probably suffering
        from either DNS problems (exim trying to do reverse lookups
        which fail) or there is a RFC1413 ident lookup being done which
        is stalling
      * Delays at RCPT TO stage normally point to verification problems
        - again either DNS timeouts, or callout problems (if you do
        those)
      * A delay after the . at the end of DATA is down to your content
        scanning setup.  Debug should hopefully give an indication of
        what was going slowly.


Thats the most likely problems - however there are other less likely
possibilities.
