I have a problem with Database Mail on SQL Server Enterprise (64-bit), Windows Server Standard 2016. If anyone who can help, I would very appreciate.
The problem is:
I moved my Data to a new server (using 1and1 server). I am using 1and1 email (ionos.co.uk) to setup Database Mail and I can send email from Database Mail to any email provider except hotmail, outlook mail. the status on sysmail_allitems is "sent"
I did setup the same way for my old server, it was working fine.
I don't know why only hotmail, Outlook mail can not receive my email.
Server: smtp.ionos.co.uk Port: 587 I also opened all the security port for mail on firewall network and firewall server.
Thank you very much.
