Check the email address on your account to see if it's still valid. When you have subscriptions, there is usually email notification of new replies.
When we get bouncebacks on emails, I have to kill notifications and subscriptions on accounts so we won't be branded as a spam source. Chances are this is what happened on your account.
I once tried to notify people of their bouncebacks and to update their emails, but half the PMs were ignored and there were several unfriendly replies. So today I just wipe the affected subscriptions silently and leave people alone.
Never mind the above, I dug through our bounceback emails. The Verizon email system is blocking all forum emails.
Hi. This is the qmail-send program at postoffice.macnn.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
Connected to 188.8.131.52 but greeting failed.

I'm not going to try again; this message has been in the queue too long.

Several of our Verizon members have used their whitelist form to try and get the block lifted. So far no dice. I'd suggest trying that, along with contacting customer service. In the meantime, use another email address for your subscriptions. With Verizon not listening, there doesn't seem to be anything we can do.
