Hi all.
Hope someone can help me

I am running a qmail/vpopmail/maildrop installation in a mail box.
Yesterday the box stopped receiving mail. All mail was rejected with
the error:

"421 unable to read controls"

After a quick search in the net i solved it chmodding
/var/qmail/control/rcpthosts.

But i was yet to discover what could cause this , as this box was
running smoothly for months.

The last think i did was add and delete a domain via popmaild. So
today i tried again. Logged to the server via popmaild

add_domain sample.com
list_domains
del_domain sample.com

and bang...the server stops receiving mail.

bash-3.00$ telnet xxx.xxx.xxx.xxx 25
Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx.
Escape character is '^]'.
421 unable to read controls (#4.3.0)

vpopmail version is : 5.5.3 (downloaded from http://www.inter7.com/vhostadmin)





I think you want to stay in the 5.4.x-tree, if you want to run it on a production-system and keep your sanity.
(And your customers)
