sendmail error :-(

Hi all,

My problem is on :

SunOS "MY_HOSTNAME" 5.7 Generic_106541-14 sun4u sparc SUNW,Ultra-60

I get the following message on the console login screen:

sendmail[23665]: MAA 23665: SYSERR: putoutmsg (NO-HOST): error on output channel sending "550 none...User unknown": I/O error.

Does anyone know which file should I check for that?

I went through /etc/mail directory and checked the "aliases" and the "main.cf".

Is there something that I should be looking in specific ?

Are there any log files to check any furter details ?

Cheers

The above number "23665" is only a counter I suppose. It increaments by 5(+5) everytime the message shows up in my screen.

Any ideas please ??

I can shed a little light here. That "MAA23665" sounds like a mail id. I would grep for that string in your mail logs which are often in /var/log/syslog.

And 550 is just a normal smtp error which is documented in the rfc.

But I don't know why you are getting an i/o error. I have never seen that error.

That is a good idea. This is what I get when I "tail" the "syslog" file.

It mentions that the below directory is "World writable". The thing is that there is NOT any .forward.isgsi01 file or dir. Here is the info.

Your /home directory is world-writable.

Take a look at that "To: none" line. Looks pretty unusual to me.

Sendmail error (found on Solaris 7 common error messages):
550 variable... User unknown
============================
This sendmail(1M) message indicates that the intended recipient, specified by the address portion before the @ (at-sign), could not be located on the destination host machine.

Check the email address and try again, perhaps with slightly different spelling. If this doesn't work, contact the intended recipient and ask for a proper address.

For information on how sendmail works, see the Mail Administration Guide.

I have changed the /home dir to 755 and now is NOT world-writable. The message is still there.

I think the sendmail is trying to send a mail to user "none" which does not exist. Do you guys know where to look about the users. I have checked all the usual places.

I have checked the dmesg and this is what I get :

Any ideas what is the core dump for the /usr/dt/bin/rpc.ttdbserverd.

See below.
