who cares ...
... about their mail servers anyway? Only idiots tie themselves with an ISP-provided mail address.
Honestly, there are more important things to worry about... If the spooks can track all our f'ing e-mail, why the hell can't they shut down the f'ing spammers?
Couldn't give a toss about this non-news... the ISP provides a good unrestricted service to most ('pakman' one exception, possibly down to local problems with Openreach facilities), at a low price.
PN cut back on the other things (USENET server with binaries, web hosting, free domains) to what an ISP/telco more generally offers, a connection (and option line rental plus calls package). Oh, and a fixed IP if you ask (and pay a once-only, small fee, of a fiver).
My guess is that those who make most noise about things being rotten (just like the responses to the 'news' that Firefox and Chrome allowed users to {shock, horror} view their site-related passwords) probably don't even use the service or product anyway.
Comments about Firefox/Chrome made me laugh - as if the developers are really interested in some negative comments on one 'foreign' web site, anyway!
