My sendmail is configured to deliver via LMTP (Unix socket listened to by Cyrus).  So I don't think it uses Cyrus' deliver executable.

I also wonder if it has anything to do with MailScanner.  I run a two stage SMTP queue.  SMTP mail is received and stored in /var/spool/ and then MailScanner ( scans it for viruses.  If the mail is clean it moves the mail to /var/spool/mqueue which another sendmail process regularly flushes.

How would I go about checking my 8 bit settings??

Hi Oliver,

I've seen this many times.  "Service Unavailable" is sendmails
interpretation of the exit code from it's delivery process (in your case,
probably cyrus' "deliver" binary).

It has been one of three things in my experience.

1.  The "deliver" binary does not have permission to write to the mail
spool - unlikely if you've changed nothing, and it's just started happening.

2.  The binary is corrupt.

3.  The email is malformed - probably spam, not to worry.  Actually, just a
thought, check your 8-bit settings as well.

Hope this helps.
