[Dovecot] [OT] preferred clients

[Thomas Berezansky]

Didn't notice that my reply to this didn't include the list (the  
default reply option due to having my address directly was "to  
sender", not "to list" due to a local setting). Only noticed after the  
fact.

My response:

One of my IMAP folders has over 13000 messages and is handled fine,  
but I am not currently sure how much actual space that is taking up  
right now. I suspect it isn't even half a GB. However, Microsoft  
states (http://support.microsoft.com/kb/830336) that Outlook 2007  
doesn't use the 2GB limited format for anything by default, and that  
the default limit is 20GB as a result, likely with registry options to  
allow it to grow larger.

The only issue I see with "deleting messages doesn't make them go  
away" is that "delete" on an IMAP account is "flag as deleted" by  
default, which means you need to issue an IMAP purge command. As I  
don't use "trash" folders I prefer this behavior, even in Thunderbird  
and Horde. I just add the purge commands to my toolbar. I think the  
flagged as deleted thing is what you are thinking about with the "some  
sort of compact operation", and is technically how IMAP is supposed to  
handle deletes.

For that issue, there is a "Purge items when switching folders while  
online" option, per account, that can be enabled. Also, the showing of  
deleted items is optional (when shown they, in all clients I have  
used, have a strike-through applied to them).
