I'm finding some of these in my mail queue. Do these make any sense to anyone? No sender? It appears to be using the server for a relay, but you have to be logged in to send,

exim -bp
Code:
 8m   837 1YOUrc-000ANJ-MS <>
          [email protected]

 1m   715 1YOUy3-000BRT-OR <> *** frozen ***
          [email protected]

Matching Log Entries

Code:
2015-02-19 12:26:12 1YOUrc-000ANJ-MS <= <> R=1YOUrL-000AMe-GL U=mail P=local S=837 T="Autoreply: \"Re:Great rates on Prudential Term Life Coverage Available Through 2/19/15\"" from <> for [email protected]

2015-02-19 12:32:51 1YOUy3-000BRT-OR <= <> R=1YOUxx-000BPG-7Y U=mail P=local S=715 T="Autoreply: \"Most-wanted satellite Internet providers tomr\"" from <> for [email protected]

Here is one from an expanded log:
Code:
2015-02-19 11:51:46 1YNl5G-000BN2-FS Unfrozen by errmsg timer

Thanks!

Makes a lot of sense if you wade through the RFCs :).

An empty sender means the email is coming from the Mailer-Daemon. On your server the mailer daemon is exim.
