This feature can be used to impersonate other software (e.g. web browsers). - 'protocolHost' can also be used to control the client SMTP protocol negotiation HELO/EHLO value. - Initial FIPS 3.0 support. - Client-side 'protocol = ldap' support * Bugfixes - Fixed a transfer() loop bug. - Fixed reloading configuration with 'systemctl reload stunnel.service'. - Fixed incorrect messages logged for OpenSSL errors. - Fixed 'redirect' with 'protocol'.
