Kloxo-MR Technical Helps / Can't send mail to external domains

« on: 2016-03-07, 09:46:50 »

Hi, I don't seem to be able to send (external) email from Kloxo.

I can receive emails.
I can send emails to local domains (i.e. on the same VPS)
rDNS is correctly setup by my host.
My host has confirmed that they do not block mail in any way.
intoDNS seems to suggest everything is fine.

I have run through all of the repairs under "additional info" here: http://forum.mratwork.com/kloxo-mr-tips-and-tricks/%28tip%29-how-to-setup-qmail-on-kloxo-mr/

I do see an error in /var/log/maillog (I've XXXXX'ed the gmail address that I've tried to send to).  I do see the same error trying to send to other domains as well.
