I think, this might only be the case if your postfix is configured to accept just one concurrent connection, i.e. master.cf: # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (no) (never) (100) # ========================================================================== smtp inet n - n - 1 smtpd What do the postfix Logs say?
