Mail queued for unknown users should be...

...returned to sender with a 'no such user' warning

When this option is enabled, messages that arrive at the server destined for unknown yet supposedly local users will be returned to the message originator. If you wish to customize the contents of the "No Such User" warning email, you can do so by creating a text file called "NoShUser.dat" and placing it in the "MDaemon\app\" folder.

...sent to the 'Postmaster' alias

By default, messages that arrive at the server destined for unknown yet supposedly local users will be forwarded to whatever user has been aliased as the postmaster. Disable this option if you do not wish to send these messages to the Postmaster.

...sent to the bad message folder

By default, messages that arrive at the server destined for unknown yet supposedly local users will be routed to the bad message queue. Clear this checkbox if you do not wish to send these messages to the bad message queue.

...forwarded to another mail server

Use this option if you wish to forward messages to another mail server when they are addressed to unknown local users.

Host name or IP

Specify the host name or IP address to which you wish to forward the messages.

The following applies globally anywhere within MDaemon where you are allowed to specify a host to forward, copy, or send email to. If you enclose the host in brackets (e.g. [example.com]), MDaemon will skip MX record lookups when delivering to that host. For example, if this option contained "example.com" then MX lookups would be performed normally. If, however, that option contained "[example.com]" then only the A-record lookup would be performed.

AUTH logon/password

Enter any necessary logon/password credentials for the mail server to which you are forwarding messages addressed to unknown users.

SMTP 'MAIL' value

This address will be used in the SMTP "Mail From:" statement, used during the session handshaking with the accepting host. Normally the sender of the message is used in this portion of the SMTP envelope. If you require an empty command (MAIL FROM <>) then enter "[trash]" into this option.

Port (default = 25)

This is the TCP port that MDaemon will use to send the messages. The default value is port 25.
