They are managed by AOL now. Access is thru mail.aol.com. Will they return to Verizon?

That's interesting. As far as I understood AOL mail was handled by Yahoo at this point.

I haven't seen any indication that Yahoo handles AOL mail but I don't see internal stuff.

The setup page for ext access to verizon.net/AOL accounts has a verizon domain for SMTP & POP and an AOL domain for IMAP.

eg: pop.verizon.net smtp.verizon.net imap.aol.com

Hopefully this indicates that control over all verizon.net email accounts will fully revert to Verizon. Well, more like a blind wish. AOL mail management has been a little onerous - like mandating quarterly login to the webmail portal, else get locked out of POP access.

My understanding is similar to oaththrowaway, these are all internally handled by the same backend systems.
