I have been having problems with POP 3 and Gmail in that some emails are there 
but seem not to download.  I have established (with the expenditure of some 
time) that the mails download (I have sat and watched them do so) and then 
disappear.  I have forwarded the mails through two Gmail addresses and one 
totally different email provider.  In every case they simply disappear.  They 
don't even land in the wastebin.

Has anyone any ideas, *please*.  

My next idea is to destroy all my filters and gradually restore them and see 
if the recalcitrant emails are being misfiled in some mythical and 
non-existent folder.  But that is a large task, and I am loathe to do it if 
someone can offer something easier or more sure of success.  I would be doing 
it in desperation, and not in expectation of success.

Thanks,
Lisi
