# Add one SOCKS proxy per line.
# Supported formats:
# host:port
# host:port:user:pass
# host|port
# host|port|user|pass
#
# Examples:
# 127.0.0.1:1080

# When rotate_ip is true, the app validates this list, keeps active proxies,
# and rotates through them evenly during SMTP/free-send/Zimbra/EWS sending.
