Using Email at Ourshack


Each email user needs an account. These accounts are set up in VDM. The user ID is not usually related to the e-mail address.

Mail can be accessed by Webmail, or downloaded to your own device using POP, or accessed from multiple devices using IMAP. IMAP is compatible with Webmail, but POP really isn't as it removes all messages from the server.

When your account is set up you will be given information about it:

e.g. This is the address that people use when sending mail to you. You will normally use this address when sending out mail so that people can reply.
User ID
e.g. fred27 This is the name that identifies you to the mail server.
e.g. a8@#bqUzl Keep the password secret! This is how you prove who you are, as nobody else should know the password for your account.


IMAP mailboxes can be accessed using Web mail - you will need to configure your account the first time you use it, to include things like your e-mail address.

Reading mail

Ourshack supports two protocols for reading mail: IMAP and POP3. It is common to use POP3 when you want to download all your mail to your own computer, and IMAP when you want to keep your mail folders on the server. In fact, both protocols are capable of being used in either way but client software usually behaves differently depending on which you select.

Set your IMAP or POP host to:

You will need to supply a user IDs and password when connecting to the server. It is common to configure the user IDs into your mailer and to supply the password each time you connect.

IMAP and POP also support SSL and TLS encryption, and you should enable these for greater security. If you have not already done so, you should import the Ourshack master certificate into your mail client to support this.


IMAP users may wish to create folders on the server. Your mail client should have a way to do this. It may show the folders as a tree, or with names like INBOX.myfolder

Note that the server always regards user folders as being `under' the INBOX so you may need to specify names like INBOX.myfolder when you want to create myfolder

It is possible to have mail delivered directly into sub-folders if you set the IMAP permissions to allow the user `anonymous' to post to that mailbox. Mail addressed to mailname+mailboxname@domain will go directly into the mailbox called INBOX.mailboxname

Sending mail

You should configure the `from' address in the mail client to match the address known to the server so that people can reply to your mail.

Most e-mail clients use SMTP to send mail. The SMTP server is:

and you should use port 587 (the standard SMTP port is 25, but many Internet Service Providers block that port).

To prevent spammers from using Ourshack as a relay site, we require that SMTP clients supply a user IDs and password so you must also configure your mailer to do this.

The server supports SSL and TLS encryption for greater security, so this should be turned on if possible. Before using it for the first time, you should import the Ourshack master certificate into your mail client.

Automatic filtering

IMAP users can have mail filtered by Sieve scripts. This can be used to file mailing-list traffic in separate folders, and to sort spam and virus messages.

See Using Sieve scripts to filter mail automatically for details.
