You can issue the command: postconf maximal_queue_lifetime to display the value postfix is using. > > I do not have long queue ids turned on. Is it still safe to wait a > month There are possible race conditions with normal "short" queue ids. Either enable long queue ids or stop postfix before removing old "defer" files. I suggest enabling long queue ids. The only reason to not enable long queue ids is if you're using some ancient log analysis tool that can't parse the longer IDs. http://www.postfix.org/postconf.5.html#enable_long_queue_ids > and then wipe out any files in the spool older than 30 days? Only files in the "defer" directory, not any files in the spool. -- Noel Jones
