Topic: [SOLVED] SMTP Error: SMTP error(451): Failed to add recipient

Hi Folks,

I am trying iRedOS and just insatlled the same. Installation was pretty smooth but when I try to send email to others I keep getting below error in maillog.

Jul  8 00:08:35 mx1 roundcube: Invalid response code received from server (451):
Jul  8 00:08:35 mx1 roundcube: [08-Jul-2011 00:08:35 -0400]: SMTP Error: SMTP error: Failed to add recipient 'xxx@xxx.xxx' in /var/www/roundcubemail-0.3.1/program/steps/mail/func.inc on line 1365 (POST /webmail/?_task=mail&_action=send)


Any clue why?

Please paste related postfix log in /var/log/maillog, not just log of roundcube.

It seems there is some issue with iRedAPD. I have gone through the documents and didnt find any files for iRedAPD in iRedOS.
is it not included with iRedOS?

iRedAPD service is not running.
Please start it immediately:

# /etc/init.d/iredapd restart

It will log in file /var/log/iredapd.log, If it doesn't work, please check its log file first.

Great ..Thnks a ton..I just resolved the issue and mail routing is working as it should be. I appeared to be ireapd issue only.
