Domain Properties

Use the Domain Properties to add a mail domain alias, enable IIM (Ipswitch Instant Messaging), enable virus scanning, and set other message and mailbox properties.

Domain Properties

Domain Name (Official Host Name or OHN ). The current domain name used to address mail to the users on the mail domain is displayed. For example, company.com is the domain name in the address john.public@company.com.

TCP /IP Address. Select a primary or virtual IP (if displayed) address from the list box.
Top Directory. Enter the name or Browse to the directory where users, lists, and web files for this mail domain are stored.
Domain Aliases. Specify alternate domain names for which you want the mail domain to accept mail. Multiple aliases are separated by a space. This field is limited to 255 characters.
Example: If the mail domain name is mail.domain2.com , you can set an alias of domain2.com so that IMail Server accepts mail addressed to fred@mail.domain2.com and fred@domain2.com.

Note: Host Alias requires also that the proper updates to DNS must be made to work correctly.

Note: If the Domain Alias name is changed, stop and restart all services via the Service Administration page in order for the change to take effect correctly.

Domain Options

Enable Ipswitch Instant Messaging (IIM) (selected by default if available in software version). Specify whether the current mail domain will allow access to the Ipswitch Instant Messaging service.

Enable Web Calendaring. Specify whether the current mail domain allows access to the Web Calendaring Service (if available in software version).

Note: If Enable Ipswitch Instant Messaging and/or Enable Web Calendaring is selected at the mail domain level, it can be selected or cleared for each user of the mail domain on the User Properties page.

Enable Virus Scanning (selected by default if available in software version).

If this option is selected, virus scanning is performed for:
- the primary domain
- any virtual domain (IP-less) that is bound to the primary domain
If this option is cleared, virus scanning is performed for:
- any virtual domain (IP-less) that is bound to the primary domain and has the antivirus option selected at the virtual domain level.

Note: The primary domain is identified in the Domain Name box.

Message and Mailbox Options

Default Maximum Mailbox Size. (0 is default value). Enter the default maximum size (in bytes, KB, MB, or GB) of all the mailboxes in each user account. Enter zero for an unlimited mailbox size for each user.
Max. Outbound Message Size. (0 is default value). Enter the maximum size (in bytes, KB, MB, or GB) of an outbound message. Any message that is larger than the size entered will be bounced. Enter 0 for an unlimited maximum outbound message size. For more information, see File Attachment Settings.
Single Message Maximum Size. (0 is default value). Enter the maximum size (in bytes, KB, MB, or GB) of a single message. Messages that exceed this size are returned to the sender. Enter 0 for an unlimited single message maximum size. For more information, see File Attachment Settings.
Full Mailbox Notify (percentage). (0 is default value). Enter a percentage that users will be notified when their mailbox is within a specified percentage of being full. Enter 0 for no full mailbox notification. Example. See also Customizing the notification message.
Default Maximum Messages. (0 is default value) Enter the default maximum number of messages allowed in each user's mailbox. Enter 0 for an unlimited number of messages.
Full Mailbox Notify Address. Enter an additional address where an email will be sent when a user's mailbox is almost full. For example, this could be the system administrator's address.
Maximum User Count. (0 is default value) Enter the maximum number of users that can be registered for this mail domain. Enter 0 for an unlimited number of users.

Tip: The user count configured on the Domain Properties page DOES NOT include Root.

Sub- mailbox Creation. Select how to handle a message when it arrives for a user and is addressed to a sub-mailbox that does not exist. Select one of the following actions:
- Create. Creates the sub-mailbox and delivers the message.
- Send to Inbox. Does not create the sub-mailbox. Instead the message is delivered to the "main" mailbox.
- Bounce. Bounces the mail back to the sender as an invalid email address.
Minimum POP Frequency (minutes). Enter the number of minutes delay between POP logins for each user. The default is 0 (or unlimited) logins.

Caution: If you enter any number of minutes for Minimum POP frequency, you are limiting popping to one mailbox per user per domain. If you create more than one mailbox for a user, that mailbox will receive mail, but the user will be unable to access it unless the POP frequency is set at 0 (zero). An error message is sent to the client and logging in is denied, Different email clients may handle this error differently.

Example: Outlook and Outlook Express display the userid/password dialog box continuously. If you click Cancel, the error message the POP server returns is: "-ERR login frequency exceeded - try again later" User Database Setting
