We are having difficulty sending to one site, the logfile indicates rl-recv: Blocking call cancelled and requeues the message until it finally times out and is returned to the sender. the kb has a document that says to add a paramater to EnablePMTUDiscover and set it to 0 which changes the MTU to 576 bytes. We have iMail 6.06 on a Win2k server. Is setting this value what others do or should I leave it alone or is there other rationale for the Blocking call cancelled smtp error? thanks, bob Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
