Hello everybody! it seems to me that when qmgr wants to deliver an email via smtp, qmgr "assigns" it to a smtp process. As long as there are no concurrency needs, the same smtp process is used repeatedly.... even for diferent domain destinations. Ok so far!
NOW, if one smtp process delivery takes long, long long... until it dies for the watchdog timeout, all smtp deliveries assigned to that smtp process fail! and qmgr send them back to deferred queue.... Is there any way to force postfix to use one smtp process for each delivery so if one fail the others get delivered? Thanks in advance! David.
