Hello,
I have sendmail installed on several servers of different customers.
When I run sendmailconfig on some server I get message:
WARNING: local host name (;; connection timed out; no servers could be
reached) is not qualified; see cf/README: WHO AM I?
As we can see there in brackets is an error message instead of true
local host name. This message is returned from dns lookup procedure. But
dns lookup has no problem (responses are pretty fast):
hostname -f
server.example.com
host server.example.com
server.example.com has address 10.22.19.126
host 10.22.19.126
126.19.22.10.in-addr.arpa domain name pointer server.example.com
host -t mx example.com
example.com mail is handled by 10 server.example.com.
cat /etc/mailname
server.example.com
That error message appears on some lines in sendmail.cf too:
Dj;; connection timed out; no servers could be reached
Cw;; connection timed out; no servers could be reached
CG;; connection timed out; no servers could be reached
Which results in situation when other mail servers refuses e-mail from
this server for that nonsense name. I must repair it myself "by hands",
but Debian has "helpful" feature - after reboot is sendmail.cf
autogenerated again with those error messages inside.
Can you help me?
Thank you very much
Viktor Matys
