Yes, the troll476 address in your Address Book may be no longer existent. That email may have been closed.
Or do you mean, the entry in your Address Book seems not to come up at all? as opposed to the address when email is sent to it not being there... ?
Thank you - you may ignore the solicitation for additional services (and with them, charges). I did not send that message to you, the website system did. (And I have no control over such messages.)
I could try from my own email, and see if that address is undeliverable, but I'd rather not.
It could have changed, or been removed (e.g. for violation of Terms Of Service, e.g. if it was sending a lot of emails at once, i.e. spamming type behavior, etc. etc.)
Right. Are you the manager of the troll476 account?
If you cannot log into it any more, to manage it, then it's gone for sure. That's one way of making sure, and finding out, at your leisure and convenience of course.
