I'm receiving a 451 4.3.0 System I/O error (in reply to end of DATA command) error from Postfix when trying to deliver to cyrus-imap and not really sure why. I'm on CentOS 7 (2.4.17-8) after downgrading from current version. I'm using Kerberos GSSAPI to connect to the front end, but authentication appears to be working fine as I can see authenticated when enabling LMTP debugging in Postifx. All messages are refused for delivery though. I'm not sure what to do. Any suggestions?
Any chance that Kerberos is negotiating a security layer? -- Kenneth Murchison Cyrus Development Team FastMail Pty Ltd ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
