masqmail-0.2
view src/libident/id_query.c @ 171:349518b940db
added support for STARTTLS wrappers
added the route config option `instant_helo' which
causes masqmail, as SMTP client, not to wait for the
server's 220 greeting. Instead if says EHLO right at
once. You'll need this for STARTTLS wrappers that
usually eat the greeting line.
