The e-mail address of your mailboxes can be used in the form of
email@example.com. If you have set
up additional domains then
firstname.lastname@example.org will also work.
Plus addressing allows you to give out alternative addresses like
email@example.com that still arrive at your
mailbox. You can create a filter rule to automatically filter messages sent to plussed addresses,
which can be helpful for managing mailing lists and site registrations.
The spamfolder needs to be enabled to use plussed mailaddresses.
Setup a new mailbox¶
To add a new mailbox to your Uberspace, run the
uberspace mail user add <mailbox> command and enter your password when prompted. So to add the mailbox
post, run this command:
[isabell@stardust ~]$ uberspace mail user add post Enter a password for the mailbox: Please confirm your password: New mailbox created for user: 'post', it will be live in a few minutes...
Nothing is shown while entering your password; that’s absolutely correct and works as intended – just enter it blindly and press Enter!
While some special characters such as
_ are allowed in mailbox names, there are rules limiting their usage. Please make sure your mailbox name adheres to these rules.
Your mailbox password has to comply with a set of rules:
A minimum length of 8 characters.
Not only letters.
Not only numbers.
Not prohibited by us.
A password score of
We prohibit the use of some passwords we deem too common (like
test1234) or too easy to guess, e.g. if your mailbox name should be
fn0rd, we will reject
testfn0rd as a password.
In addition to the above, we also check your password using zxcvbn. This results in a score for your password, based on how easy it might be guessed and / or cracked (higher results mean a better estimated password strenght). We require a password score of at least
If we reject your password, we try to give you an error messages that explains why. Hopefully it will help you to choose a fitting alternative.
We strongly recommend to use only ASCII characters in your password. Non-ASCII characters may work in some circumstances, but this depends on the encoding used by your client being compatible with the one used by the mail server.
List existing mailboxes¶
You can list your existing mailboxes using the
uberspace mail user list command, e.g. if you have setup mailboxes for post and info:
[isabell@stardust ~]$ uberspace mail user list info post
To change a mailbox’s password, run the
uberspace mail user password <mailbox> command, so in order to change the password for the mailbox
post, run this command:
[isabell@stardust ~]$ uberspace mail user password post Enter a password for the mailbox: Please confirm your password: New mailbox password set for user 'post'.
Delete a mailbox¶
You can delete a mailbox using the
uberspace mail user del <mailbox> command. To delete the mailbox
post, run the following command:
[isabell@stardust ~]$ uberspace mail user del post Mailbox for user 'post' deleted.
You can configure any existing mailbox to be the catch-all mailbox.
A catch-all mailbox will “catch all” of the emails addressed to the domains on your account that do not exist in the mail server - this can help avoid losing emails due to misspelling. Without a catch-all mailbox these mails will get rejected by the server.
[isabell@stardust ~]$ uberspace mail catchall status No catchall configured. [isabell@stardust ~]$
To set the catch-all mailbox run
uberspace mail catchall set <mailbox>. In this example we make the mailbox
post the catch-all mailbox:
[isabell@stardust ~]$ uberspace mail catchall set post Mails, which cannot be matched to a mailbox, will be sent to post. [isabell@stardust ~]$
To remove the catch-all run
uberspace mail catchall del:
[isabell@stardust ~]$ uberspace mail catchall del No catchall configured. [isabell@stardust ~]$
With each Uberspace you will get a mailaddress in the form
USERNAME@uber.space. By default this mailaddress forwards
to the external mailaddress you have given with your registration and we recommend to keep it that way.
If you want to use the mailaddress as a mailbox, you need to remove the file
~/.qmail and the Maildir will be
~/Maildir with the first incoming mail. But as this is no ordinary mailbox, it wont work with the
Spamfolder or Sieve filter rules or plussed mailaddresses.
In the past we also promoted mailaddresses in the form
USERNAME@SERVER.uberspace.de. This may not be
available in future product versions and should no longer be used.
