Apr 1 12:00:12 sendmail[4809]: MAA04809: SYSERR: putoutmsg (NO-HOST): error on output channel sending "550 off ... User unknown": Bad file number

this message in the syslog

what's the problem..and what shall i do ??

[Alex Glennie · Accepted solution]

I beleive the problem is related to the OSSPI mail queue monitor osspi_mailq.sh script

you could either :

Restrict the security of some directories, so that sendmail doesn't give the warnings anymore:

# chmod go-w / /etc /etc/mail /var /var/spool /var/spool/mqueue
# chown root / /etc /etc/mail


or

# vi /etc/mail/sendmail.cf
(and add right after the line #O DontBlameSendmail=safe)
O DontBlameSendmail=GroupWritableDirPathSafe

Or if one doesn't care about sendmail checking any security setting add

O DontBlameSendmail=safe

Then stop/start sendmail.

thank you for your help Alex!!

one more question

i already changed name nsswitch.conf -> nsswitch.conf.old like this
because this system didn't use dns, nis...etc

but still this message in the syslog

Apr 1 16:39:18 khan2 sendmail[7564]: NOQUEUE: SYSERR(root): NIS map mail.aliases specified, but NIS not running

help me!!

[Alex Glennie]

where's the nsswitch.conf.old located ? if in /etc/ move it elsewhere.

what's the contents of the nsswitch.conf file and what do you get if you run nslookup ?

version of sendmail ?

[moon_5]

i moved the nsswitch.conf.old to elsewhere
and sendmail version is 8.9.3

$ nslookup khan1(hostname)
Using /etc/hosts on: khan1
