OK, this made no difference to the observed symptoms sadly.

Just to re-iterate the peculiarity of the symptoms:

- Only noticed it on this one account, 3 other accounts are not showing 
- It's only the Search which appears to go wrong
- I varied the Search timeframe a little to vary the size of result, 
made no difference (trying to see if it's packet length dependent or 
- Asking the client to receive ALL emails is ok (not tested, but presume 
it uses a different set of IMAP commands)

I find it very odd that it's basically a symptom on one login and not 
all logins?  Also that it's persistent through time and basically 
independent of small variations in result size (ie probably not zlib 
related or network packet size related).  I guess the main thing which 
seems different about this account is the high numbers for the IDs being 
returned, all other accounts have fewer messages and lower numbers - 
very peculiar?

Thanks for any insight?
