Advanced Options

Advanced Options

The Advanced tab allow you to control the underlying functionality of the SMTP server. The default settings on this tab should be appropriate for most installations. However, if you need to change these settings, be aware that they can change the operation of the server.

Maximum recipients per message. The maximum number of addresses that can receive a single message. The default setting for this option is 0.

Delay between recipients. Sets a delay (in milliseconds) between the delivery of messages to recipients. The default setting for this option is 0.

Port. The port that the SMTP service listens on. The default port number is 25.

Mailbox delimiter. Enter the character that is used to delimit the mailbox name in a user ID. If nothing is entered here, the default delimiter of - (dash) is used.

Note: Before changing the mailbox delimiter, check existing usernames and aliases that contain the new delimiter. Otherwise, these aliases or usernames will be delimited, which will cause incoming mail to be undeliverable or delivered to another user whose username matches the portion of the address preceding the new delimiter.

Host delimiters. The character(s) that are used to delimit a host name. Each character is seen as equivalent to the @ in e-mail addresses. By default the characters used are: @ % * : $ and &. Any of these can be used between the user ID and the virtual host name in the POP3 or IMAP4 login user ID.

Note: The @ character is required by Web Messaging.

Delivery Application. If you wish to replace the delivery application with an external program, enter the full pathname of the file in this text box.

Hello Message. Changes the text of the SMTP service welcome message. The text is limited to 400 characters or less. If over 400 characters are entered, the default message is used. To revert to the default message, clear this option.

Disable SMTP 'AUTH' command. SMTP AUTH provides a means of authenticating the user ID and password of a user sending mail. This is handled transparently by the mail server and client. When the mail client connects to the mail server, the server tells the client the authorization methods it can use. The client then sends the user ID and password to the server, and the server verifies it.

Note: Before changing the mailbox delimiter, check existing usernames and aliases that contain the new delimiter. Otherwise, these aliases or usernames will be delimited, which will cause incoming mail to be undeliverable or delivered to another user whose username matches the portion of the address preceding the new delimiter.

Note: The @ character is required by Web Messaging.
