15.2. Receiving emails on the client (POP or IMAP)

Each user automatically receives an email account with their name on the Intra2net system. This account can be accessed via POP3 and IMAP4, no extra configuration is necessary on the Intra2net system.

We recommend using the IMAP protocol to transfer emails from the Intra2net system to the client, as IMAP offers the following advantages:

  • All emails (including emails stored in folders) are made centrally accessible. They are also accessible via webmail, notebook or smartphone.

  • The IMAP protocol allows you to download just parts of an email. For example, when checking for important emails via a mobile network, it's not necessary to download large attachments in order to see the email contents.

  • Multiple users can access one account at the same time. Therefore, in the case of shared accounts (such as inbound fax, info or sales) there is no chance of multiple employees answering one email.

  • Through the IMAP rights management, it is possible to give other users certain rights (e.g. read-only rights) for individual folders. For example this can be helpful for the secretarial office or a holiday substitute.

  • Emails on the Intra2net system are automatically included in the backup and are thus never lost due to a malfunctioning computer.

  • All emails are on the server, therefore a crashed email program or switching to another program will never result in a loss of emails.

The Intra2net system internally uses the Cyrus mail server. It was developed by Carnegie Mellon University and is used for the management of multiple 10,000 email accounts. Larger folder structures or folders with 100,000 emails can be supported without complications.

[Hint]Hint

When using POP3, we strongly advise against activating the Leave emails on the server for n days option in the email client, because the POP3 protocol lacks the functionality required for reliable operation. Please use IMAP instead.
