I'm using sendmail-8.12.0.Beta16 with cyrus-imapd-2.0.16. Every time sendmail delivers a message to the LMTP daemon, it logs an error message like this: Aug 23 15:29:59 setup16 sm-mta[331]: [ID 702911 mail.warning] AUTH=client, relay=localhost [(null)], authinfo failed Apparently, the LMTP daemon is attempting to authenticate to sendmail, and sendmail is seeing invalid information. When I posted this question to comp.mail.sendmail, Claus Assmann suggested that I turn off AUTH support in the LMTP daemon. Is there a way to do this with Cyrus lmtpd? -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking-
