maxage and mu4e sent folder

[Sander Boer]

Hi,
A while ago I posted this as an issue for the MU project:

"I've sent some emails with mu4e using msmtp. emails arrive, copies in 
ofllineimap's Sent folder, all is grand.

But when I check the Sent folder on the mail server, no dice.
A quick look reveals a strange naming difference:
Mail created by courier imap look like:

1414613165.M579368P32122V0000000000000900I0000000001E600B4_0.zorn,S=819:2,S

But a mail created by mu4e looks like:

20141029-9ffdc9-sun-ra:2,S

That looks a lot shorter."

Now, as it turns out, this is no probem. When I turn off the maxage 
directive, the short named mail in the Sent folder gets synced and its 
filename in the offlineimap folder get renamed to the longer version as 
shown above.

Probem is, however, I would like to have maxage set, as my mailbox is 
9gB. And on my surface pro, disc space it is a bit of an issue.
I noticed maxage being under close scrutiny right now and I hope this is 
not compounding the issue.

thank you,

Sander

PS right now I'll just re-org older mail in archive folders and filter 
those out.
