| # |
| # Save this as ~/bin/my-gen-msgid, then add ~/.mutt-fix-msgid with the following, |
| # fixing your path to the file: |
| # |
| # my_hdr Message-ID: <`/home/user/bin/my-gen-msgid`> |
| # |
| # then edit ~/.muttrc to add: |
| # |
| # send-hook . "source ~/.mutt-fix-msgid" |
| # |
| # I like my msgid to start with the date |
| msgid="$(date +%Y%m%d%S)-" |
| if [[ -x /bin/diceware ]]; then |
| # I like memorable nonsense, so I can visually tell one message from another, |
| # by looking at the lore URL, so use diceware for that |
| msgid="${msgid}$(diceware --no-caps -d- -n2)-$(openssl rand -hex 2)" |
| else |
| # Just use openssl with some extra randomness |
| msgid="${msgid}$(openssl rand -hex 12)" |
| fi |
| # Don't leak my hostname, just use something that makes sense to me |
