exim smtp error

[SACHIN]

HI,


I am unable to send mail using php scripts. i am getting following error while sending mail using php scripts.

T=remote_smtp defer (-1): smtp transport process returned non-zero status 0x000b: terminated by signal 11

Please let me know how to fix.

Googling for: "smtp transport process returned non-zero status"

yields the following:

If you are receiving this error in your /var/log/exim/mainlog:

2006-01-10 23:01:14 1EwHYJ-0002q0-6y == user@domain.com R=lookuphost T=remote_smtp defer (-1): smtp transport process returned non-zero status 0x000b: terminated by signal 11

Then you can fix the issue by editing your /etc/exim.conf, and changing the following code:

remote_smtp:
  driver = smtp

To be:

remote_smtp:
  driver = smtp
  hosts_avoid_tls=*

Save, exit, then restart exim.

More information can be found on the hosts_avoid_tls option in section 38.8 of the Exim spec, located here:
http://exim.org/exim-html-4.50/doc/h....html#SECT38.8

Note that if you attempt to implement this change, you should do so via the Exim configuration editor in WHM, otherwise your changes to exim.conf will be overwritten at some point. Alternately, you can make the changes directly to exim.conf just to test if it works, and if it does, add it via the Exim configuration editor.

Or you might try following these steps:

1. Log into WHM
2. Click Tweak Settings under Server Configuration
3. Find the checkbox for "Prevent the user "nobody" from sending out mail to remote addresses" and uncheck it.
4. Click Save at page bottom

Not sure if this was the problem, but would be my first guess...
