# --------------------------------------------------------------------------

# To extend mail_plugins, you can either:
# 1. Create/edit /etc/dovecot/mail_plugins_extra (for global plugins)
# 2. Create/edit /etc/dovecot/mail_plugins_imap_extra (for IMAP-specific plugins)
# 3. Create/edit /etc/dovecot/mail_plugins_lmtp_extra (for LMTP-specific plugins)
# For example, to add the virtual plugin globally:
# echo -n ' virtual' > data/conf/dovecot/mail_plugins_extra
