Hello !
I work on Windows Server + Apache24 (64Bits) + PHP 7.1.7 + MariaDB 10.2.6 + OSticket 1.10
I setup SMTP email without trouble and I can receive incoming email IMAP but only send internal SMTP answer but not external ?
Inside Apache log It's notice :Failed to add recipient: ****@gmail.com [SMTP: Invalid response code received from server (code: 550, response: 5.7.1 Unable to relay)]
This are my remarks :
1 : I use Exchange 2010 and open relay is configure OK
2 : I try to another SMTP server also with open relay but same result
3 : I try to change PHP version to 5.6.31 and 7.0.21 but same result, I try also to install Apache in 32bits... but no way. same results
4 : I try with XAMPP server on my windows and It's working ?? I can use without trouble send email via my SMTP server
I really don't know at this state what can I do to fix this mistake ? Of course If I can't send confirmation to my external users, OSticket won't work for me... But in any case, why It's work with XAMPP ?
Thanks in advance for your idea and support.
