          I'm running a postfix server that relays emails from software using MailBee 11.2.0.599.  Occasionally the emails sitting in the outgoing folder are renamed from .EML to .BAD.  When I look at the logs on my mail server I see entries like this:

          Note the X's are not from me redacting information.  That's exactly how it appears in the log.

          If your mail server redacts the data in the logs, it's hard to tell. Maybe there is a way to suppress this in there.

          It's not the mail server doing that.  That's what seems to be coming from MailBee.

 Here is the greeting from the server
 [14677]: > unknown[10.203.1.10]: 220 kingaire.northtrailrv.com ESMTP Postfix (Ubuntu)
 
 Followed by the first command from MailBee
 [14677]: < unknown[10.203.1.10]: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
 
 Followed by the server saying, "What?"
 [14677]: > unknown[10.203.1.10]: 502 5.5.2 Error: command not recognized
 
 Followed by MailBee saying, "X"
 [14677]: < unknown[10.203.1.10]: X?
 
 And the server once again saying, "WHAT?"
 14677]: > unknown[10.203.1.10]: 502 5.5.2 Error: command not recognized

          MailBee cannot do that (unless you're explicitly sending such commands). Maybe there is some software in the middle.
