Hi, I haven't found any references to this, so I'll ask:
I'm using RC + dovecot + postfix. Mail messages get created/stored in the user's Maildir "new"/"cur" folders. I'm wondering how much info I can glean from the filenames, to do some statistics without invading privacy.
So, for example, I'm pretty sure that ",S" gets appended when a message is marked as Read...??? What other predictable characters are there?
Example:
- 1543626953.M281022P21036.mx1.musicplace.com,S=188628,W=191393:2,FS
I'm pretty sure that:
- 1543626953: unix epoch timestamp
- M281022P21036 ???
- mx1.musicplace.com: hostname of the mailserver
- S=188628: filesize in bytes
- W= maybe bytes on disk???
- ":" a delimiter
- 2,FS ???
But the bit I"m really interested in is after the ":", which is often "2," with additional letters. Anybody know what they mean?
TIA,
