Mail Server Information at a Glance

IMAP & POP Service Information

IMAP and POP services are used to read your emails via desktop or mobile clients.

• You should enable SSL and TLS encryption options in your mail clients.
• You can find instructions on setting up your IMAP account for Thunderbird.

Webmail Services

There are applications available to access your emails via a web interface. Use them when you have temporary access to a computer or a slow connection.

• Roundcube (Uses a modern AJAX interface)

General Issues & Best Practices

• Inbox Size: Having a large Inbox will require too much CPU resource in receiving, spam and virus filtering, fetching, and reading mails. Clean your Inbox regularly. Do not keep mails with large attachments in your Inbox. Arrange your mails in different folders.
• Performance: The response times of servers will decrease as you keep your Inbox folder large.
• POP Risks: POP protocol downloads all mails to your client's local disk. You may encounter problems when you change PCs or configuration. In case you use POP, do not forget to enable the "leave a copy on server" setting in your client application.

Automated Filtering

You can use "Sieve Language" for filtering your e-mails directly on the server.

• See the department's sieve page for an example sieve file with comments.
• The Roundcube webmail has a server-side filter editor, which is accessible from Settings → Filters.
