There are a bunch of tutorials on the web about using MailPlus Server including the manual on MailPlus Server by Synology self. But what has taken time from me was the to find out which user names I have to configure and use in the mail client (like Apple Mail, Thunderbird etc.)
So here are my tips:
- The IMAP/SMTP username is the name of the local DSM user without the domain name. If you want an adress like „hans.klein@starcompany.de“ you have to create an DSM account with the name hans.klein
- In your IMAP/SMTP mail-client application use only the user name without the domain name, e.g. „hans.klein“
- Configure your domain simple like „starcompany.de“ at the SMTP domain settings (not „mail.starcompany.de“ e.g.)
