Mercury/32 v4.72, July 2009
V4.7 introduces one of the most-requested features for
Mercury - the ability to run as a native Windows Service.
It also has a number of other smaller features and numerous
- Native Windows Service
If you purchase (or have already purchased) a
license for Mercury, you can now choose to run Mercury
as a native Windows Service, meaning that it will start
up when the system boots without needing a login, and
will continue to run if the desktop is logged out.
- IMAP Direct-connect SSL
support The approved way for clients
to connect to IMAP servers via SSL is using a special
command called STARTTLS, which Mercury has always supported.
An older connection method, where the client connects
directly to port 993 using SSL has been deprecated and
discouraged for a number of years, but client developers
are persisting in using it. Accordingly, and slightly
against our best judgment, we have decided to support
this deprecated SSL form in MercuryI.
- Ability to suppress short-term
blacklisting Mercury/32 v4.5 introduced
short-term blacklisting for the POP3 and IMAP servers
to defend against dictionary password attacks. Unfortunately,
for some sites using NAT or other "shared address"
technologies, this could result in one user's errors
locking out all other users on the server. V4.7 includes
the ability to exempt certain addresses from short-term
blacklisting in the POP3 and IMAP servers using connection
control ACL rules.
- IMAP Server reliability
improved A number of unusual or pathological
error conditions that could cause problems in the IMAP
server in earlier versions of Mercury have been
dealt with in v4.7.
- SMTP server size control
exemptions You can now specify that
certain addresses are exempt from the SMTP server's
"maximum size" restrictions, allowing
approved users to send messages of any size to or through
- Many fixes,
including problems with certain connection control restrictions
not activating correctly on some occasions, and a problem
where Yahoo alert messages using an illegal address
format in the "From" field could cause crashes.
