The explanation for this issue is in Postfix 2.6.5's release notes (http://www.sfr- fresh.com/unix/misc/postfix-2.6.5.tar.gz:a/postfix-2.6.5/RELEASE_NOTES):
240 [Incompat 20090330] Postfix now adds (Resent-) From:, Date:, 241 Message-ID: or To: headers only when clients match 242 $local_header_rewrite_clients. Specify "always_add_missing_headers 243 = yes" for backwards compatibility. Adding such headers can break 244 DKIM signatures that cover headers that are not present. 245 compatibility with existing logfile processing software, Postfix 246 will log ``message-id=<>'' for messages without Message-Id header. It is therefore intentional and the bug can be closed. ** Changed in: postfix (Ubuntu) Status: Incomplete => Invalid -- empty message-id, no date in Evolution MUA https://bugs.launchpad.net/bugs/456238 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to postfix in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
