Hello, Due to DMARC policy of several domains some mail is blocked (see an example below). I suppose maillist software ( ezmlm ) needs some tuning, it must forward email to list with own sender address ( @squid-cache.org ). An example: ------------------------------------------------------------------------------------------------------ Return-Path: <> Received: (qmail 8574 invoked for bounce); 9 Aug 2014 15:48:22 -0000 Date: 9 Aug 2014 15:48:22 -0000 From: MAILER-DAEMON@xxxxxxxxxxxxxxx To: squid-users-return-123504-@xxxxxxxxxxxxxxx Subject: failure notice Hi. This is the qmail-send program at squid-cache.org. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <motienko@xxxxxxxxx>: 74.125.142.27 failed after I sent the message. Remote host said: 550-5.7.1 Unauthenticated email from yahoo.com is not accepted due to domain's 550-5.7.1 DMARC policy. Please contact administrator of yahoo.com domain if 550-5.7.1 this was a legitimate mail. Please visit 550-5.7.1 http://support.google.com/mail/answer/2451690 to learn about DMARC 550 5.7.1 initiative. o17si27260806icl.100 - gsmtp ------------------------------------------------------------------------------------------------------ -- Regards, Oleg
