Greetings! I have installed ISPConfig as instructed by Perfect Setup Fedora Core 6, (in fact, in the last month I have installed Linux and ISPConfig more times than I have had sex...but perhaps I am sharing too much information with you.) : ) This time around, everything is working save for incoming email. I am connected via cable modem behind a router NAT is enable and the necessary ports are open Firewall is disabled I have setup several domains running on the same IP address and installed joomla on several of them and they all work fine. FTP works fine Squirrelmail can send but can't receive mail. (all accounts) I can send email using outlook but can not receive email. (all accounts) The only time I can receive email, is when I email from one of my own domains to the another one of my own domains...(both reside on the same server). here is error message from a gmail account from which I sent a test email which was returned. Delivery Status Notification Technical details of permanent failure: PERM_FAILURE: SMTP Error (state 9): 554 5.7.1 <firstname.lastname@example.org>: Relay access denied The master DNS / webserver is ns3.bchost.info and this appears in the co-domain section for all the other websites. I spent quite a lot of time sorting through threads on this forum but none of the proscribed answers worked for me. Maildir is enabled in ISPConfig /etc/postfix/main.cf (includes the following at the bottom of the page) virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names /etc/posftfix/local-host-names contains a list of all domains /etc/postfix/virtualtable contains a list all domains Please help me, as I need to get a life, but have decided not to, until I figure out how to receive email for all of my domains currently installed on ISPConfig. Thanks so much.
