I'd suspect they don't mess with that port.

It appears they are "trying" to be helpful on 143 ......

We seem to have gone off track though ....

It just seems unlikely to me they'd go to the trouble of stripping STARTTLS for virus scanning for the very small percentage of IMAP users who use STARTTLS over 143 in preference to the usual 993.

Not really - all mobile traffic is run through a small number of proxy servers, so quite easy to do......

Mobile networks and broadband networks are very very different it design, implentation and managment.

The "filtering" Vodafone is doing might be causing speed issues if the downloads are from a site with user uploaded files, like Mediafire or a number of other similar hosting services. Compare the router's DNS responses with those from a trusted DNS server to find out.

On the concrete proof of what is occurring with filtering, I added some more info here (sorry for the long post!)
