Hi,

i checked /var/log/kloxo/maillog (tail -n300 /var/log/kloxo/maillog)


and found this:


"

as you can see, recipient server (gmail) dont allow delivery of your email because detected unusual rate of emails, check the link they proveded you


But that is not issue you you asked about. You asked about [email protected] delivery failure


Your maillog file tells:

i googled above error and there is an advice from Anton Akola regarding that: http://forum.parallels.com/showthread.php?73883-qmail-local-delivery-to-root-failures&amp;p=314182&amp;viewfull=1#post314182
I checked mentioned "locals" file on your VPS and it appears it contains only "localhost" so i assume adding your hostnames (mail.yourhosteddomain.com also) line by line may help. Then restarting qmail (service qmail restart)


Also there is a good advice: http://serverfault.com/a/449317
(but might not be related to the issue, its another case)

hope that point you to right direction


PS: there are scripts in Kloxo like /script/fixmail ; /script/fixpop i think, but im littlebit afraid to use them to not mess the things, but it may also help
