Persistent IMAP connection?

[Ray Jackson]

Hi all,

I've had a browse through the archives and found discussions about the 
possibility of implementing persistent IMAP connectivity during an IMP 
session.  Has anybody implemented anything yet?  Are PHP4+ themselves 
going to implement anything here?  Here we have 13k users and without 
such a feature our IMP webmail just isn't scalable (without buying new 
hardware and dedicating extra resources to our webmail service).

I know IMHO can do something here - but we don't want to use Roxen and I 
love IMP - so can anybody give me the low-down on whether such a feature 
will EVER be made available for IMP?

Failing that - any suggestions on how to improve the performance of IMP 
would be welcome (we must use uw-imap/sendmail).

Many thanks,
Ray Jackson

4.0.4 (plus a CVS download of the new PHP 'PEAR' libraries).  We are 
using LDAP for our data store.
