So for a number of years Vodafone have been operating a spam filter on the mail servers.

Yes it's a good idea, I'm sure that it picks up heaps of spam and stops my inbox from been cluttered up with pills for this that and the other thing, timeshare and internet banking account alerts at banks I don't even have an account with.

Sometimes the occasional bit of spam does find it's way thru to my inbox, but that is to be be expected.

Here is the problem I have, what happens to all the genuine email that gets swept up by the spam filter? Is there anyway for me to see exactly which emails are been collected by the spam filter and alert Vodafone to the genuine ones so they can tweak the filter or allow this particular email address to no be filtered out?

I'm sure there are genuine emails been caught in the spam filter, A particular company I have 2 accounts with, one using my vodafone supplied email address and the other using a gmail address, as far as I can tell I get all the emails to my gmail address, but my vodafone address only *sometimes* gets the emails, So I could get in contact with vodafone and get them to tweak things to allow the emails, but recently I've now noticed that a 2nd place that i've used my vodafone address at is suffering from the same problem, yes a easy fix was to change to my gmail address.

But this raises a big question, how much other genuine email is been filtered out? How do I find out which ones?
