https://discuss.frappe.io/t/https-and-http-email/23559/22
But now
i cant send emails from my server to any domain (hotmail.yahoo)
But i cant send to Gmail
i dont know why Gmail dont accept mails from my erpnext
for example
my erpnetx mail is
[email protected]
that mail can send to any mail domain like ( hotmail-yahoo )
while cant send to Gmail
so i doubt in Gmail spam , i didnt find it as a spam or as inbox
so i thought may be the problem in erpnext
so i send message from outlook ([email protected]) To Gmail
The Mail is arrived to the Gmail
what is the reason i dont know
