rename .eml (apple mail) email with senddate

[rue]

Hi,

After manually dragging emails out of apple mail (Big Sur) to a target folder
I'd like to have Hazel rename the *.eml file with the emails' send-date, or the day I received the email.
date created / date modified does not work.

You'll probably have to do it based on Contents. Look up "match patterns" in the manual for details on how to use custom attributes and pattern matching to pull that info out.
