Roller Network Help - Hosted Mail Box Accounts

Hosted mail box accounts allow you to deliver mail to accounts on our server, allowing the Roller Network to provide mail hosting for your domain. This feature can also be used for emergency delivery purposes for Secondary MX or SMTP Redirection domains. Mail box accounts are used in conjunction with outbound mail accounts to allow you to send and receive mail through our services. Hosted mail boxes are also used as mail mirror storage.

We support IMAP and POP3 accounts with TLS/SSL. You may use any standard mail client (such as Outlook, Apple Mail, Thunderbird, etc.) or one of our webmail clients ( to access a mail box account. ActiveSync push mail is also available, see server configuration below. This service is IPv6 enabled.

Server Name

For IMAP and POP3 use as the server.

For server details see the Server Information page.

For ActiveSync push mail use as the server and leave the "domain" blank. ActiveSync is provided as-is without technical support.

Configuring Mail Box Accounts

To add mail box accounts, simply click on the "Add New Mail Account" button and choose the account type you wish to create. Accounts may be created as a "Regular Account", which is a standard user@domain.tld account, or as an "Any-User Account", also known as a catch-all or dropbox account which will accept messages addressed to any user at your domain. You may choose to have a corresponding Outbound Mail account created with the same name and password as this hosted mailbox. You should normally create a corresponding outbound account. (Corresponding accounts are required to send mail through webmail since the webmail clients will try to authorize using the same user/pass you logged in with.)

When you create a mail box account or outbound mail account, the user name for that account is the full email address (or domain including the @ symbol) as shown in the account control center. You may create an unlimited number of accounts.

If you're setting up a new hosted mail domain:

  1. Add a new mail domain in "Hosted Mail Domain" mode.
  2. Configure filtering options.
  3. Create mail box accounts.

If you have an existing domain you want to convert to hosted mail:

  1. Create mail box accounts.
  2. Change the service mode to "Hosted Mail Domain" mode.

If you don't have your own domain name or just want to use one of our rollermail.* domains:

  1. Create mail box accounts.

If you need to use mail box accounts for emergency delivery for an existing domain:

  1. Change the service mode to "Accept and Hold Messages".
  2. Create mail box accounts for every user in the domain. Users without mail box accounts will be rejected, so if you can't create accounts for everyone, we recommend creating an any-user account to accept everything.
  3. Change the service mode to "Hosted Mail Domain".

IMPORTANT: Mail boxes must be created before switching the domain to hosted mode in order to prevent messages from being lost. Once a message is bounced, it's gone forever. The valid user table for domains in hosted mode is derived from the list of configured mail boxes; any preexisting user table settings will be ignored. It is not possible to selectively deliver messages from the queue to a mailbox. We recommend setting a domain to "Accept and Hold" mode during configuration.

Although we offer a set of hosted domain names (,,,, you will not be able to modify the filtering parameters or view logs for these domains. To fully utilize settings available in the account control center you will need to bring your own domain name.


IMAP - When using IMAP, all of your mail (including folders and subfolders) are stored on our mail server. This lets you connect using any computer and still have your entire folder tree available wherever you go. Your mail program will only download messages to display them as needed, so you won't ever have to wait for all of your messages to download before you can start reading your email. All modern mail clients (including most cell phone mail clients) support IMAP.

POP3 - With a POP3 account you only have one folder stored on the server: your inbox. Any folder you create will not be available anywhere except the computer which you created it on. With POP3, your mail program will download and delete messages from the server, and you do not have to remain connected to the internet. This is a good alternative to IMAP if you are charged per-byte for internet access. If you have previously used IMAP, you will not be able to access any of your IMAP folders while using POP3.

Disabling IMAP or POP3 Access

If you need to disable a protocol from accessing a hosted mail box, select IMAP Enable/Disable or POP3 Enable/Disable from the actions selector. The default is to allow both protocols. When a protocol is disabled, attempting to access the mail box will result in an authentication failure. Webmail is not available when IMAP is disabled.

Clearing a Mail Box

Warning: there is no recovery option after running this command.

To clear a hosted mail box, select the "Clear Mail Box" option. You will be asked to confirm your action.

This option will delete all messages for the selected hosted mail box account (except the shared namespace from other accounts), but it will not change the structure of the account or remove any Sieve scripts. Folders and other metadata will remain intact.

Deleting a Mail Box

Warning: there is no recovery option after running this command.

To delete a hosted mail box account, select the "Delete Mail Box" option. You will be asked to confirm your action.

This option will delete an entire hosted mail box account (except the shared namespace from other accounts), including all folder structure, any Sieve scripts, and all other metadata in the account.

Mail Boxes as Mirror Storage

Hosted mail box accounts are used by the mail mirror feature as storage. If a mail box is being used as mirror storage it is indicated by the "Mirror # Days" message in the status column with the expiration time for messages in that mail box. When all mirrors pointing to a mail box are removed, the expiration time is automatically removed and it becomes a standard hosted mail box.

Disabling a mail box will also disable the mail mirrors that use it for storage.

Deleting a mail box used as mirror storage also deletes the corresponding mail mirrors.

Recipient Delimiters (Address Extensions)

When changing away from the default of + it's important to note that the Postfix processes on the mail box servers are only able to recognize + as a delimiter. The alternate delimiter settings are intended for customers running their own servers. If you need to use an alternate delimiter, create a self-forwarding entry i.e. " forward to mail box". This will strip the extension before sending it to the mail box but it will still be in the headers.
