Thanks to everyone for the replies

Have to say that I've been on the phone most of the morning trying to sort out ongoing stuff from when I was away down south so time is at something of a premium right now let alone trying to sort out logistical stuff back home having been away 10 days.
>>1. Create redirects for new mail for your key aliases (eg penny2006) so that (hopefully) legitimate mail remains separate from what will be an ever-increasing tide of spam.
Don't understand about redirects (sorry - remember you're dealing with a technical dipstick here

). Don't want to send the mail "somewhere else" as my present inbox rules are set for the existing downloads (and I don't have time to re-do them). Is it not possible to just set up (say) mailboxes for all the "to" addresses I want to keep, and download them separately through the roll....+penny.... facility on OE? Having said that, the penny2006 mailbox I set up over 12 hours ago still isn't working either on webmail or OE so I'm struggling somewhat with understanding (at all) how this all works.
>>2. Create blackhole redirects for aliases that you don't use (and which pull a lot of spam - webmaster, sales, info, etc are usually good targets)
Not feasible (sorry) - huge percentage of it all is to random addresses @ happ....
>>3. PN may be able to re-queue the existing mail so it goes back through the redirects - this would enable mail to your blackholed aliases to be removed.
That sounds wonderful, presuming that (a) "mailboxes" rather than "redirects" are viable (b) that the new mailbox set-ups actually start to work with either OE or Webmail (getting invalid password when I try to use either at present, but mainmail, set up originally, works so I assume that the newer mailboxes haven't actually yet been enabled at the F9 end).
>>4. Use something like MailWasher or similar (or IMAP) to get a list of headers.
Not technically-skilled enough to set this up, and no time right now.
>>5. Sort this by subject line to enable large blocks to be marked for deletion.
>>6. Process deletions in smaller blocks (eg like stopping OE partway through a send/receive cycle to avoid the process crashing)[/quote]
Because of the sheer volume of e-mails (well over 50,000 by now) OE can't even get to the point of starting to download messages (server timeout set to maximum which says five minutes).
From what I dimly understand, if I were to set up (say) 50 mailboxes (not redirects) to siphon off the mail I actually need, and if the mailboxes were actually to become operational, and if F9 were able to requeue the mail, the existing mail would then re-filter into the new mailboxes and I could call the separate sets of mail off into the new mailboxes via OE. (yes?)
Also (presumably) I would need to have preset something on the default mailbox such that everything not putting itself into a designated mailbox when requeued by F9, would get blackholed. (I don't understand how to do this bit either, but logically it would seem to have to be in place before the requeuing took place) (?).
I can (probably) find the time to identify the 50-ish addresses I need mailboxes for, on an ongoing basis, and set up mailboxes for those some time today as well as setting the same ones up in OE, but there seems to be a long delay in the mailboxes actually starting to work, which presumably they would need to before requeuing could start (if indeed requeueing is possible).
I hope I've summarised all this as accurately as I can in terms of my (very) limited understanding of the processes. Everything just seems more than slightly surreal right now so I'm just hoping that some sort of solution can be found to enable at least the bare essentials of mail to be accessed and dealt with, and the rest cleared; have to be elsewhere right now but will check back periodically over the day when I can.
Thank you all again

Penny.
Footnote - just found two e-mails to penny2006 have just arrived. *no* idea how they got here (both sent today) and apparently OE still can't access the roll....+penny2006 mailbox (and the default mailbox still isn't operational) .... but *something* must be working. Mystified but marginally saner
