The Email role provides the following services:
- POP/IMAP (dovecot)
- SMTP (postfix)
- Spam filtering (rspamd)
Installing the Email role will allow you to create hosting packages with email addresses and forwarder-only accounts. The customer can send messages through SMTP and receive with POP/IMAP. The username is always their email address.
If a website is mapped to an email role (see 'server placement'), that website will be able to send messages using the sendmail binary or PHP mail(). A drop-in sendmail replacement is added to the PHP container which sends through the website's SMTP using a hidden mailbox.
