Fail to send Mails from Samsung Galaxy Note
I have setup my Galaxy Note to receive email from zimbra but i can only manage to receive but when i try to send it fail.
Is there anything am doing wrong?
I've open port 993(imap over ssl), 995 (pop over ssl), 587 (Mail submission over tls) and 25 (incoming mail to postfix).
The structure is like this:-
Zimbra -> SMTP Marshall(mail scanner) -> Firewall
so all mails from zimbra are going to SMTP Marshall then are sent to the outside world. The same route for incoming mails from outside.
Internally(within LAN), clients connect directly to zimbra.
The only thing i did for the opened ports in the firewall is that i've mapped those ports to zimbra. So users can access emails from outside, but when they try to send it fails.
