HI, I guess what you want oto achieve is to find the hostname so that you can send SMTP mail through your server.
But if you're using lotus notes you wont need it THe notes server gets the mail from the client and if it sees that it is an SMTP e-mail it sends it through the SMTP server built in it otherwise delivers it as Notes Mail.
A calendar profile lets you set your C&S preferences.
You can access your calendar profile by opening your calendar and choosing Tools - Preferences, and then clicking the Calendar & To Do tab.
For instance, the “Beginning of the work day" and “End of the work day" choices determine the hours displayed in the scheduler details in a calendar entry.
