[imp] Opening folders painfully slow - SOLVED

[Paul Gardiner]

Just singed up the the list to ask a question and then found the
solution before I'd manage to ask. Thought I'd post anyway in
case it helped someone else in a search.

I have a few fairly big folders, one around 50,000 messages. I was
finding these would take ages to open. Worse, when a large folder
did eventually open, something had timed out, and I was shown
no message. Checking my server, it still had an imap process
whirring away. When that eventually stopped, retrying to open the
folder would be successful, but - I think - only because the
messages had all been pulled into the server's memory file cache.
In any case, opening the folder again at a later date would
fail.

The solution was simple. In the imp config, under the Server tab,
I had sort_limit set to 0. I set it to 1000, and now everything
zips along at breakneck speed. I can't believe I'v had this set
up wrongly for the years I've been using imp, but there ya go.

One question I still have. Is the need for this setting because
of the imap server I'm using? I use courier. Might another
handle sorted request more efficiently? Or might I not have
the best configuration set up for courier?

Cheers,
