My ISP, att.com, has blocked a number of European IP addresses, including two, which I badly need to contact.  Here's the skinny from the KDE forum, one of these addresses:
...[the blacklist] covers entire datacenters as our servers are all in
completely different IP blocks, even at the /8 level and they're all
blacklisted - and this is with at least two different datacenters run
by different providers.

The only way to get these emails (after spending most of a day in chats and on the phone) seems to be to open a Gmail account.  So, I started to do this.  Naturally I wanted to use jonrysh@gmail.com, since my current email address is jonrysh@pacbell.net.  Unfortunately it seems that when I opened my Google+ account some years ago jonrysh@gmail.com was assigned to me automatically; since I never used it, Google deleted it.  And a Gmail expert writes me:
Email addresses once used can never be reused in Gmail.
Even the address has been deleted at some point in the past, Gmail does not allow you to reuse the address ever again.

With Gmail having around 1 billion users now, even many unusual words are taken or have been taken at some point in the past.
Only option is to choose another account name.

Maybe I should move to China or somewhere else where I won't be oppressed by big businesses (8-).
