Topic: Can't send or receive, smtp error 451

Hello guys, I had a sucessful instalation of iRedMail before in a VPS in DigitalOcean, but after I try to install ruby (rvm and rails) the server stopped working...

So I deleted the server (completely) and created another... Installed apache, mysql, blablabla and installed iredmail sucessfully.
But when I try to send an e-mail they said to me "SMTP Error: SMTP error(451): Failed to add recipient".

And when I try to send from gmail to my iredmail account I don't receive the e-mail.

Could you help-me? I don't know why doesn't works, iRedMail is really simple to install...

Thanks for the support, cheers! ;)

Re: Can't send or receive, smtp error 451

Check if cluebringer is running... what is the result of:

service postfix-cluebringer status

Look for the entries from cluebringer (cbpolicyd) in /var/log/syslog while trying to restart it...

Re: Can't send or receive, smtp error 451

Well, I don't know why, the postfix-cluebringer looks like running fine, and the /var/log/syslog is empty...

root@NUDESERVER:/home/jackson# tail /var/log/syslog
root@NUDESERVER:/home/jackson# service postfix-cluebringer status
 * cbpolicyd is running
root@NUDESERVER:/home/jackson# tail /var/log/syslog
root@NUDESERVER:/home/jackson#

Re: Can't send or receive, smtp error 451

OOOOHHHHH

I'm very stupid... a big mistake in the DNS record...

TXT Record was
dkim._domainkey    TXT    "v=DKIM1; p=....."

I change to:
"v=spf1 ip4:myIP -all" TXT    "v=DKIM1; p=....."

Works fine, sorry to be so stupid. big_smile

Thanks for the support, cheers!
