Yesterday I installed exim 4.11, first we had the lookup-problem
(nis/dbm (most probably ldap will be affected too)).
Now I have this in my logs:
2002-12-12 20:01:10 SMTP call from another.host [111.222.111.222]
dropped: too many nonmail commands
another.host is a server of a friend of mine, running as backup-mx for
some of my domains, the server runs exim 4.10.
Due to a line-problem at my provider today he spooled some mails for me.
When the line came back, and another.host tried to deliver, the above
errors occured in the log, (counted 8 of these so far).
