Postfix receive mail problem Hi all, I installed "the perfect server debian i386 lenny ISPConfig" version. Everything is working just fine. I thought! Yesterday i was testing squirrelmail and i could send an email from the server to my my emailaccount at home...GREAT ! The test was to reply that mail that mail to see if i could receive an email in my squirrelmail account ... and that didn't happend. So i can send mail from any account made in ISPConfig, but i can't send it back from my computer to the server, so it would arrive in the webmail box This is the code from the mail .. Code: firstname.lastname@example.org SMTP error from remote mail server after RCPT TO:<email@example.com>: host fallback.mail.widexs.nl [188.8.131.52]: 550 all relevant MX records point to non-existent hosts What is wrong?
