After update, mail error - 421 unable to read controls

[Crashys]

After update to 10.1, the mail server is not sending emails.

A telnet to port 25 of the server shows wrong host/domain configuration and that 421 error.

*****:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
421 unable to read controls (#4.3.0)
Connection closed by foreign host.

What can i do to solve this? Any ideas?

1. Disk space partition in /var that it is not full

2. The directory /var/qmail/control exists with chmod of 755 and ownership of root:qmail. There are a number of different permissions in there. If don't want to blanket the directory with 755 take a look at everything inside and make sure it is a minimum of 644. If you see something less fix that individual file.

3. The file /var/qmail/control/options exists and is more than 1 byte in size.


Does the server reboot without errors?

If you do the following:

service qmaild stop

Do you still show anything on tcp 25? i.e.

netstat -lntpe | grep :25

When you start up qmail, are there errors in /var/log/maillog?

service qmaild start
tail -f /var/log/maillog

Did anyone find the solution to this problem? I am having the exact same problem on Plesk 12
