E-mail providers such as Gmail or GMX offer the possibility to retrieve mails from other providers’ inboxes, allowing you to handle mails from different providers in a single account. Here are a few things to consider:

In order to use a mail retrieval service, you need to leave your password with the corresponding e-mail provider. If you want to use some webmail account to pick up mails from your TUM-inbox and share your login data, this leads to two problems:

If you want to collect your TUM-mails in another inbox, please use the mail-forwarding in TUMonline. This will lead to the same result, without you having to disclose your account information.
