The ETRN (?§11.8.2.6 on page 433) ESMTP extension allows sites that connect to your
sendmail daemon to force the daemon to process the queue on demand. For sites that
support dial-up hosts??™ mail, this is a useful and valuable feature. For sites that prefer to
process the queue only when they want to, this feature might not be desirable. To disable
the ETRN feature, just define this privacy flag. By disabling it, you cause the following
ESMTP reply to be sent when the ETRN command is attempted:
502 5.7.0 Sorry, we do not allow this operation
restrictexpand ?§24.9.86.14 on page 1069 Restrict who can use -bv (V8.12 and later).
restrictmailq ?§24.9.86.15 on page 1069 Restrict who can run mailq(1).
restrictqrun ?§24.9.86.16 on page 1069 Restrict who can process the queues.
