I have an exchange 2013 running to support my personal domain and the smtp smart host is currently set to smtp.verizon.net. Up until the drop dead date of 8th? of march, all good and functional for outbound email from my personal domain.
march 8th and on, outbound email relayed thru smtp.verizon.net, which as was stated in another reply, has ben alysised to an AOL server, received:
Diagnostic information for administrators:
{edited for privacy}
mtaout-aaa02.mx.aol.com #553 5.7.1 <dcr@MYPERSONALDOMAIN.com>: Sender address rejected: not owned by user {edited for privacy}##
where {edited for privacy} is my previous and current, now AOL, verizon email address.
I cannot fathom I'm the only one on the Verizon FIOS net residential customer that has taken it in the shorts with the switch to AOL.
Any suggestions?
