Hi, I receive every day pdf reports. I have now more than 1800 mails, which takes a lot of space. Every first day of the month, the report is a summary of the month, and I would like to only keep those one.
I know how to filter mail using ~d. But that's only for one specific day. I tried something like ~d 1/*/* but got 'invalid month */*' Also tried ~d 1/[1-12]/2022 but got 'invalid month [1-12]/2022' How could I do? Thanks, s.
