Adding a New IMail Domain

Use the domain options to add a new mail domain.

General Domain Settings

Domain Name (Official Host Name or OHN ). Enter the domain name used to address mail to the users on the mail domain. For example, company.com is the domain name in the address john.public@company.com.
TCP /IP Address. Select Select an IP Address to use an IP address (domain) for the mail domain or select Virtual (virtual IP address) to use a non-IP-ed domain.

Note: If you change a primary domain to a virtual domain, you must restart ALL services. See Changing the IP Address of a Host for more information.

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.

Note: If you change the Domain Alias name, stop and restart the SMTPD service in order for the change to take effect.

Domain Options

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

Note: If Enable Instant Messaging is selected at the mail domain level, it can be selected or cleared for each user of the mail domain.

Enable Virus Scanning (selected by default if available in your 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.

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.
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.

Note: If you set up a virtual host (domain), each virtual host has an independent Single Message Max Size setting. However, the value configured for the domain bound to the IP address to which SMTP client connects to may override the Single Message Max Size setting configured for the virtual host.

For example, if the host bound to the IP address that the email client connects to for email delivery has a 5 MB max setting and the virtual domain that the client is sending email to has a 10 MB max setting, IMail's SMTP service will not accept a message larger than 5 MB.

IMail Web Messaging, however, accepts messages based solely on the Single Message Max Size setting of the local destination domain.

Full Mailbox Notify (percentage). Enter a mailbox size percentage of which users will be notified. 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.

Note: The Maximum User Count does not apply to virtual hosts that are based on the Windows NT user database or an external database. The displayed counts of users for hosts that use the NT user database or an external database may not be correct.

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.

User Database Setting

User Database Type area, select one of the following:
Save. Click to save your settings.
