Thanks. I see the following example in some of the imapfilter docs. I'll have
to stare at it until it makes sense. If anybody can offer any assistance,
please chime in. Until then, I will be reading lua documentation.

all = myaccount.mymailbox:select_all()
for _, mesg in ipairs(all) do
mbox, uid = table.unpack(all)
header = mbox[uid]:fetch_header()
body = mbox[uid]:fetch_body()
message = header:gsub('[\r\n]+$', '\r\n') ..
'My-Header: My-Content\r\n' .. '\r\n' .. body
myaccount.myothermaibox:append_message(message)

(It is very unlikely that they offer this service given their attitude about messing with the headers in your email.) You can run procmail on your ISP's computer. In the procmailrc, write a filter that passes the incoming email through program, formail, which is a general purpose email reformatter, which you use to send each email through the program, sed, the stream editor and have sed apply the 'sed s command', 's|***UNCHECKED***||' to each email. If you can string all this together on your ISP's computer, it will delete *all* instances of ***UNCHECKED*** wherever thet occur in emails. In theory, it can be done but it seems like an awful lot of work with very little payoff ;-) -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

The last time I mentioned wanting to do something like this, what was recommended to me was procmail, which would sit between the upstream server and your mail client. I never investigated (my circumstances at the time didn't lend themselves to its being a practical solution), so I don't know what the mechanics of the whole thing would be or how the mail flow would look, but it could certainly do that type of filtering. It may not be ideally suited to use with IMAP, but Googling on 'procmail IMAP' (without quotes) finds a couple of hits which look like they might be decent leads - either on how to do it with procmail, or on possible alternative solutions. If you find a solid solution, please let me know, as I'd be interested in something like that myself; it's just never been important enough for me to make a project out of it. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
