What causes lmtpd to get a "System I/O error"?

[Rob Tanner]

Hi,


I've put up and testing a new install of cyrus-imapd-2.2.3 and postfix 2.0.19.  The one problem I'm seeing is using ther vacation capability of sieve although filing, discarding, rejecting, forwarding, etc all appear to work correctly.  Vacation responses generate a System I/O error, and an example from the maillog is quoted below:

>  status=deferred (host /var/imap/socket/lmtp[/var/imap/socket/lmtp]

My experience tells me that this is probably either a missing file component or a permissions error, but I haven't been able to ferret it out.  Can anybody give me some pointers?


Thanks,
Rob
