Exim Panic Error

vikasumit · 05-17-2006, 03:01 AM

Hi,

I have install exim few minutes before and to test it out, I start following guidelines given in the exim documentation.

as given in there to test a mail I should do this

Code:

[root@Sumit rc.d]# exim -v sumit@example.com
From: sumit@localhost.com
To: sumit@example.com
Subject Testing Exim on local machine

This is great
.
LOG: MAIN
  <= root@Sumit.190 U=root P=local S=361
delivering 1FgFhY-0000qG-EC
[root@Sumit rc.d]# LOG: MAIN PANIC
  User 0 set for remote_smtp transport is on the never_users list
LOG: MAIN PANIC
  == sumit@nethuesindia.com R=dnslookup T=remote_smtp defer (-29): $
User 0 set for remote_smtp transport is on the never_users list

I got this error in Panic Log

Code:

[root@Sumit rc.d]# cat /var/spool/exim/log/paniclog

Any idea whats wrong i did ?

user 0 is root. the never_users list is a lite of uid's who can not send mail to various places, and in this case it is the remote_smtp transport. i.e. root is not allowed to send emails out of the local machine. makes sense to me. you can remove or override the never_users list if you really want, but it's not recommended.

Hi,

I would like to get your point on this, I mean why root cannot send mail out? Also while doing configuration of Exim, I set EXIM_USER=root I guess that is Root is allowed user, infact Exim will run as root user (also a recommanded in exim configuration). Or Shall I make new user say exim and run application as that user?

Thanks

the uid is the uid of the user who has opened a connection to the smtp server, not the own of the server process itself. you really shouldn't be sending mail about to and from root, only local stuff like logs and thigns would be suitable for root to send emails. try sending as a normal usre and it should go through that just fine.

Hi,

I did it this way

Code:

[root@Sumit rc.d]# exim -v sumit
From: sumit@localhost
To: sumit@nethuesindia.com
Subject: this is subject

This is test message for eamil to be sent through Exim

Thank

I have sumit as user in system with user ID as 500, Not sure why it can make lock file though I found
a zero byte file in /var/mail/ with name as "sumit" .

Edit:
Just to mention /var/mail is synbolic link to /var/spool/mail and have 777 permission where as /var/spool/mail is
directory with 775 permission (user root and group mail)

Thanks
