I'm a list owner of a list hosted at listserv.dartmouth.edu. Last night, all of our yahoo.com and aol.com subscribers were deleted after several days of errors. The errors messages were: For Yahoo subscribers: Last error was: 5.4.300 550 5.4.300 Message expired -> 451 [RL01] Message temporarily deferred or for AOL subscribers: Last error was: 5.4.300 550 5.4.300 Message expired -> 421 4.4.2 Connection dropped due to SocketError I have manually added the subscribers back in, but expect that errors will begin again. Anyone else experiencing this or have suggestions? Has there been a policy change with Yahoo and AOL that is no longer compatible with ListServ? Thanks in advance.
