Existing Customers Using IIS SMTP Server Method

If you are currently using our IIS SMTP Server Method, you may wish to migrate to one of the options above.

Migrating to Option 1 (A&B) – Amazon AWS would be a ‘like for like’ replacement but would offer enhanced features such as DKIM and supporting sending over SSL/TLS. You could also migrate to Option 2 – SMTP Relay and you would benefit from your internal protocols and policies for your email servers.

Options 3 & 4 (Reply To methods) should only be considered if you cannot implement Options 1 or 2 as they give a reduced user experience.
