System Configuration and Maintenance Frequently Asked Questions

Posted 2010-07-03 16:39 by Joe

Can I run each service on a different machine?

Yes for some services, no for others.

It is possible to use LDAP for mail user configuration, though this is not a comprehensive solution. Many of the features of Virtualmin can be re-implemented manually on the mail server, using Webmin and Usermin, but per-domain spam/AV configuration is not possible in this setup. The other option is to use Virtualmins ability to run commands before or after creation/update/delete of user accounts. One could write a custom command that makes use of ssh to perform actions on a remote mail server.

Email Frequently Asked Questions

How do I set up a catch-all email address to receive or bounce invalid inbound emails?

Note that this is not recommended. It breaks the ability of the mail server to reject mail early in the delivery process, which means your system will work dramatically harder because full spam messages and viruses will have to go through the full processing chain.

Spam and Anti-Virus Scanning

Posted 2008-12-30 21:40 by Joe

Spam and Virus Scanning

Virtualmin allows you to enable spam and virus scanning on a per-virtual-server basis, and to configure what happens to email classifies as spam or virus-laden. Under the hood, it uses the popular SpamAssassin http://spamassassin.apache.org/ package for spam detection, and ClamAV http://www.clamav.net/ for viruses.

SpamAssassin assigns each message it scans a score indicating how spammy it is, based on the content and servers it was sent from. Typically, anything with a score above 5 is regarded as most likely spam.

Troubleshooting Common Email Problems

Troubleshooting Email

Mail is perhaps the most complex component in a Virtualmin system, combining a mail transfer agent (usually Postfix, but optionally Sendmail or qmail), a mail delivery agent (usually procmail), POP3/IMAP retrieval (usually Dovecot), anti-virus (ClamAV), anti-spam (SpamAssassin), and mail log analysis (Virtualmin's built-in mail log analysis tools, and optionally logwatch and others).

Configuring POP3 and IMAP Clients

Posted 2008-12-30 20:50 by Joe

POP3 and IMAP and SMTP Authentication

Virtualmin configures the Dovecot POP3 and IMAP server for usage with all common mail clients, and Cyrus saslauthd for SMTP authentication on outgoing mail.

POP3/IMAP Username

You can always find the username for a user by looking on the Edit Users page for the virtual server in which the user exists. It will be displayed in the IMAP/FTP login field.
