## Common questions

### How do I point a Dockerized Roundcube at my IMAP and SMTP servers?

Set ROUNDCUBEMAIL_DEFAULT_HOST to your IMAP host and ROUNDCUBEMAIL_SMTP_SERVER to your SMTP host. Prefix the host with tls:// for STARTTLS or ssl:// for SSL/TLS encrypted connections.

### Which ports should I expose for Roundcube and its mail connections?

The Docker example publishes container port 80 as host port 8000 for the web UI. IMAP defaults to port 143 and SMTP defaults to port 587, with environment variables available to change them.

### Which Docker tags should I use if I want ongoing updates?

Use the latest-* tags, which contain the latest stable Roundcube release and updated PHP base images. Full version tags are not updated after release.

### Can users log in without typing the full email address?

Yes, set ROUNDCUBEMAIL_USERNAME_DOMAIN to append a domain to user names during login.

### Does Roundcube support PGP encryption?

Yes, Roundcube provides support for PGP encryption.
