Postfix reject outgoing mail originate from external network
by k_oudom from LinuxQuestions.org on (#57V8X)
I've been searching for days and finally I have to ask. Thank you.
I have an ISPConfig server which run postfix as smtp. I can send and receive email using roundcube webmail but I can't send email from Outlook email client with or without SSL. It just keep sending... however I can receive email in Outlook. Here is some log. Sorry for masking xxxxx
