Quoting Jose Manuel Blanco <[email protected]>:
Regarding the IMAP server side suggestions, the thing is that my old
webmail (Horde 3.0.10+IMP 4.0.4) is connecting to the same IMAP
server, and it has no problems dealing with large inboxes -1 or 2
seconds max. for displaying inboxes with more than 40000 mails never
been cached-, so my question remains: has the imp code changed in a
way that would explain that behaviour? For example, when I click in
the Date tab to reorder my messages, my old webmail only reorders the
ones that are visible
No. As previously described - this can NEVER happen with IMAP. IMAP
requires a full sort of ALL messages in the mailbox - not a mailbox
slice.
while the new one goes to the first (or last) page instead. This
suggests that the old one is only dealing with the ones that are
visible, but I can't be sure. The settings are the same in both
webmails as far as I can see.
What is probably happening is that somewhere between IMP 4.0 and IMP
4.3 sorting got fixed. So clicking on Date now correctly sorts by the
date in the headers of the message vs. the IMAP sequence number (which
is often a date sort, but not always). Sorting by sequence numbers is
extremely fast because it is the only operation that doesn't require
sorting at all - you can just grab a message slice. But sorting by
sequence numbers is also not very useful since messages may appear to
be in a random order. That's the tradeoff.

Thanks for your answers, Michael.
Since I'm dealing with a community of hundreds of users with huge
mailboxes, I'm afraid the new horde slowness is going to determine if we
can go to the new one or stay in the old one. I'd like to try as a last
option this "sorting by sequence numbers", just in case it speeds up
logins, but I 'm not sure if that is an option in the imp 4.3, unless
it's the "Arrival date" one (that I have already tried).
The other options I see are Message date, From, To, Subject, Size and
Thread view.
Cheers
Jose Manuel
