Hello all, I follow tutorial here http://www.howtoforge.com/virtual-u...er-mysql-and-squirrelmail-fedora-14-x86_64-p6 and get postfix working with send email but not receive email from outside. I can send email to my Yahoo email but I can't get any reply from Yahoo email. I also don't get any errors return from Yahoo mail. Did I do something wrong? Please help me. Thanks all.
