I didn't really take a good look at SpamFire the other day when I 
downloaded it... but am I to understand you correctly that SpamFire 
DOWNLOADS the mail, then filters it, then RESENDS it back to the SMTP 
server to wait for you to collect it?!?

First, what happens if you don't collect your mail, does SpamFire 
continue that download/upload process on the same messages?

2nd: What does it do about the SMTP Envelope headers that will now be 
altered because it downloaded the messages and re uploaded them (ie: the 
envelope will claim the message traces back to SpamFire rather than the 
original source). Does it leave the proper chain of headers in place so 
you can see where it was before SpamFire messed with it? If so, I guess 
they just hope the ISP doesn't strip extra envelope headers (some do, 
leaving you only with the last set of headers).


Wouldn't it make WAY more sense to never download the message at all? 
Read the message on the server, apply the filters, and if a message 
should be filtered, delete it from the server. If a message shouldn't be 
filtered, leave it alone to continue to wait on the server until you 
collect your mail.

Yes, that still downloads the message (can't read what isn't downloaded), 
but it avoids the whole upload bandwidth/munge the envelope issue.
