I had a bounced bounce in my mail queue:
-chiark:~> mailq
7d 4.7K 10wUvn-0003X5-00 <> *** frozen ***
D pinard@???
ian@???
...
-chiark:~> exim -Mar 10wUvn-0003X5-00 ijackson@???
Message 10wUvn-0003X5-00 has been modified
-chiark:~> exim -Mmd 10wUvn-0003X5-00 ian@???
Message 10wUvn-0003X5-00 has been modified
-chiark:~> exim -M 10wUvn-0003X5-00
-chiark:~> mailq
-chiark:~>
The message was generated by an autoreply in my personal filter file.
The original message was discarded; the autoreply is supposed to
inform the sender where to send mail. The autoreply had a typo in the
BCC recipient - it CC'd it to ian@??? (note the
extra `e').
Then I made the same typo in the new recipient. The result was that
the autoreply was discarded !
Below are the log entries and a copy of my exim.conf (with various
irrelevant bits removed).
Why did Exim decide to throw this message away ? How can I persuade
it not to in a similar situation in future ? Why is that not the
default ?
Ian.
