stop receiving mail but keep processing mail in queue

2017-09-14 Thread Rosenbaum, Larry M.
How would we set Postfix to stop accepting incoming mail yet keep processing any queued mail? We are migrating from RHEL6 physical to RHEL7 virtual. Postfix version 3.2.2. Also, can we copy the queue over? Thanks, Larry M. Rosenbaum Oak Ridge National Laboratory

TLS outbound logged as "Anonymous"

2017-08-07 Thread Rosenbaum, Larry M.
We are running Postfix 3.2.2 on RHEL6, with opportunistic TLS enabled. When our central servers connect to most of our other local non-Postfix systems, the connection is logged as Trusted: Aug 7 08:00:01 emgwy1 postfix/smtp[2445]: Trusted TLS connection established to exchcs31.ornl.gov[128.219

We are interested in getting an outside service to do round-trip monitoring of our mail servers (i.e. check that SMTP mail is flowing in and out and send a notification if it isn't). [We are not interested in services that send an email to one of our mailboxes and checks it with POP or IMAP.] Ca

What would be the best method for (temporarily) blocking all mail from a particular (internal) IP? Or alternatively, blocking all mail with a particular "MAIL FROM" address? For instance, blocking all mail from 1.2.3.4, or alternatively, from bro...@badhost.example.com
