Thanks!

Me too, but in many cases I have to search for the author of the message without
remembering if the message was sent directly to me or via a mailing list.

However, with mailing lists adopting DMARC, the From: header is being
manipulated and can't be trusted for searches anymore [1].
If it's hard to understand what is happening, look at the From: header from this
archived mbox [2] sent to libc-alpha.
You will notice the different email addresses in From: and Reply-To:. I hope it
helps to understand why a search for from:tuliom would not return that message.

The mailing list had to do this so that people with a DMARC-enabled email could
continue to receive messages from the mailing list.

I see.
