  • What can I do when my mail box is full?

    To see the actual storage of your mail box you have to log in to your online mail account. On the top right of this website you will find the login button. The available storage and how much is currently in use is found in the Mail tab.

    There are several options to ensure sending and receiving mail when you are running out of storage.

    • You can order more storage. Please contact our support, we are happy to increase your storage for you.
    • Delete the e-mails you do not need anymore.
    • If you are using a local software to read your emails, it is possible that your locally deleted mails are still stored online. To delete those, log in with your account (on the top right of this website you will find the login button) and open the menu beside your trash folder to empty the trash bin (last option).
  • How many recipients can one E-Mail have?

    The technical limitation of recipients per Mail is 1'000.

    Please note that sending mass mailing is not allowed. More information can be found in our "terms and conditions" paragraph 4 and 5.

  • How can I change the password of my e-mail account?

    Please log in to our Selfcare-Interface on to https://selfcare.stepping-stone.ch. Make sure you also change the passwords set for the email client on your local devices such as phone and laptop.

  • What are the e-mail settings for my client?

    The settings for our Mail Server are:

    Secure IMAP (SSL) Server


    User name




    Your E-Mail Address

    Your E-Mail Password

    Secure POP (SSL) Server


    User name




    Your E-Mail Address

    Your E-Mail Password

    SMTP (Auth via STARTTLS) Server


    User name




    Your E-Mail Address

    Your E-Mail Password

    Please take into account that you must also enter your user name (your e-mail address) and your password into the mail programme.

    To send e-mails, you must activate STARTTLS encryption for the SMTP server; moreover an authentication (SMTP Auth) is required.

    Naturally you can also use your WebMail to easily and independently send/receive E-Mails.

  • How do I get more storage for my mailbox?

    You can purchase additional storage by sending an email to support(at)stepping-stone.ch. Please specify in the email how much storage you would like to buy. We will notify you once the change has been made.

  • What size e-mail attachments can I send and receive?

    Our mail server is restricted to 50 MiB (this also includes the message text and headers). However, when an e-mail is sent or received, other mail servers, with different restrictions may be involved, over which we do not have any influence.

    Please also note, that most attachments will be base64 encoded. This results in an overhead of approximately 33% in size. Thus a file with a size of 20 MiB will actually use about 26.6 MiB disk space.

  • I receive no more Spam e-mails, what is the matter?

    In that case, you must be satisfied with our Spam Filter, thank you ;-)
