I have started a Exchange Server for a small company which has around 30 employees.
Exchange Server is hosted in Datacenter with one static IP address. This IP address will be used to send mails.
I have checked this IP address with various blacklist IP sites and confirmed this IP is not blacklisted.
I have also updated the PTR Record of this IP addres to the domain name which will be used to send mails.
Any other configuration required to reduce the chances of mails going in junk box?
Do I need to register with any service or something?
Any help will be appreciated.
