System I/O error

[Fatemeh Taj]

Dear All, To install and test cyrus2.0.16, I have installed it in new directories (and kept old directories related to Cyrus2.0.7) in /usr/cyrus16 and /usr/local16. It has no problem, but when I send email to this host I got such a message. Maybe it does not because of cyrus, but I don't know how fix it. Can you help ?     Oct 22 09:09:25 hostname sendmail[1046]: f9LF5Fi00439: to=<[EMAIL PROTECTED]>, delay=14:34:10, xdelay=00:00:00, mailer=cyrus, pri=1560153, relay=localhost [[UNIX: /var/imap/socket/lmtp]], dsn=4.3.0, stat=Deferred: 451 4.3.0 System I/O error   Thanks F.
