Hi, i send a email to my server but i get Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <postmaster at mercadeoeficaz-cr.com>: Relay access denied (state 13). So i google and i see this If your having the issue where you send a email to a email account on your Ispconfig server and you receive a message like this: Relay Access Denied State 14 You will need to double check your postfix config. Run this command below to fix two entries in your postfix install. postconf -e 'virtual_maps = hash:/etc/postfix/virtusertable' postconf -e 'mydestination = /etc/postfix/local-host-names' After that restart postfix. service postfix restart And you should no longer receive that message. I do it, but now i dont get any message when i sending from gmail to my server(something good) but i cant see the email in my server and cannot send. And as i dont get any error i cant google for a solution, when i send just get in waiting for mercadeoeficaz-cr.com. this is main.cf https://dl.dropbox.com/u/11417336/main.cf.txt and this is master.cf https://dl.dropbox.com/u/11417336/master.cf.txt
