I hope I have the right forum, sorry I'm new here :o . Messages I send from my Hotmail to any AOL address are now being returned by the Postmaster. This is the message I get:
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
Diagnostic-Code: smtp;500 SYNTAX ERROR, COMMAND UNRECOGNIZED
LINE BY ITSELF
It started with just one AOL address but now it's all of them.This has just started to happen and I haven't made any changes to my computer.
Any help much appreciated.
