Date: Mon, 30 Jun 2014 08:05:16 -0400 X-IsSubscribed: yes I've tried reporting this several different ways, apparently into a black hole, so I'll try it here on the front list. I preiodically get messages from ezmlm to the effect Hi! This is the ezmlm program. I'm managing the cygwin#cygwin.com mailing list. Messages to you from the cygwin mailing list seem to have been bouncing. I've attached a copy of the first bounce message I received. The referenced attached message is from the Yahoo/AT&T mailer and the key thing is an error message + URL, which apparently ezmlm never passes to anyone responsible: Permanent Failure: 554 REPLY: 554_5.7.9_Message_not_accepted_for_policy_reasons. See_http://postmaster.yahoo.com/errors/postmaster-28.html Checking the supplied URL reveals that the cygwin list does not comply with the sender verification magic that Yahoo wants to see when an email comes from a Yahoo/AT&T address and is to be distributed to an AT&T/Yahoo adress. I have a bellsouth.net address which now falls under Yahoo/AT&T (and I'm sure there are many others on the list in a similar situation). This means that *any* message *to* the cygwin list *from* an AT&T/Yahoo address will not be delivered to me (or any other AT&T/Yahoo user) and will be kicked back, putting us all on ezmlm's naughty list. This is not something I can fix -- it has to be addressed at the mailing list level as noted in the error URL. I apologize for putting this here, but hopefully someone wil now see it.
