Mailu comes with multiple base features, including a specific admin interface, Web email clients, antispam, antivirus, etc. In this section you can enable the services to you liking.

A Webmail is a Web interface exposing an email client. Mailu webmails are bound to the internal IMAP and SMTP server for users to access their mailbox through the Web. By exposing a complex application such as a Webmail, you should be aware of the security implications caused by such an increase of attack surface.


An antivirus server helps fighting large scale virus spreading campaigns that leverage e-mail for initial infection. Make sure that you have at least 1GB of memory for ClamAV to load its signature database.
A Webdav server exposes a Dav interface over HTTP so that clients can store contacts or calendars using the mail account.
Fetchmail allows users to retrieve mail from an external mail-server via IMAP/POP3 and puts it in their inbox.
Oletools scans documents in email attachements for malicious macros. It has a much lower memory footprint than a full-fledged anti-virus.
