Smart mailbox submailbox setup question

I don't think this would require any knowledge of which e-mail addresses belong to me. What would be sufficient is to make a sub-mailbox for every e-mail address involved in any of the e-mails in the mailbox. So, for instance, if you had:

To: Mr. A
From: Ms. B
CC: Mr. C, Ms. D

and:

To: Ms. D
From: Mr. A
CC: Mr. E, Ms. B

you'd have five sub-mailboxes, one each for Mr. A through Mr. E. The e-mails would appear in multiple mailboxes as appropriate. The contents of each sub-mailbox would be as follows:

Mr. A: E-mail 1 and e-mail 2
Ms. B: ditto
Mr. C: E-mail 1 only
Ms. D: E-mail 1 and e-mail 2
Mr. E: E-mail 2 only

Yes, such a solution would not require knowledge about your addresses. It would instead require that MailMate could let a single message be part of multiple submailboxes. This is not currently the case, but this is a feature also needed for Tags and therefore more likely to be implemented :-)

If it worked then you should use the virtual header named “Any-Address” (if I remember correctly) to do it. But that won't currently work correctly.

O.K., I'll patiently wait for this.

@Mike: No progress yet. Note that the current behaviour is not “by design”. Submailboxes are an advanced feature for which I originally missed the importance of handling multi-value headers. Changing this is not a quick fix and the feature competes with hundreds of other issues. Nevertheless, I haven't actually checked in detail exactly how hard it would be to fix this. I can at least promise you to do that :-)

Thanks for the feedback.

(By the way, I don't really agree that MailMate, in general, forces the user to work in a particular way. There are missing features and half-baked features, but flexibility is at the core of MailMate. You wouldn't believe the number of different email work patterns I've been asked to support and I really don't know any email client which is even close to being able to do that.)

Thanks for adding this!

There has been one unexpected side effect, however. The number of sub-mailboxes expanded to a huge amount. I traced most of these to a few e-mails from a contrator whose AOL account was hacked and used in mass mailings with super-long cc fields. After I deleted and emptied the trash on those e-mails, things shrunk quite a bit. Bit I still have a lot of sub-mailboxes for people who were incidentally cc'd on e-mails, people who are not in the "Any Address > Address - is - ______" list.

I also have various misspelled e-mail addresses showing up, as cc's to e-mails that I do not want to delete.
