v4.74 is now available from our download pages at -
intended that v4.73 be the last in the v4.x family of Mercury versions, but at a
certain point it became clear that there needed to be another update to fix a
variety of small problems before beginning the migration to version 5. V4.74
contains over 40 small fixes, and two rather more significant corrections: a
problem where messages deleted by IMAP-based clients were not actually deleted
and reappeared on the next connection has been fixed; and an issue where a site
had more than 3 MX mail servers declared but the first three were all
unavailable (which could cause Mercury to attempt to connect to the wrong host
for delivery) has also been addressed.
worth noting that the Mercury installer and executable files are now digitally
signed, using my name ("David Harris"). If your browser or installer complains
about them being unsigned, or tells you that they have been signed with a
signature that does not use my name, then the files are not authentic. A small
security measure, but we believe it is quite worthwhile.
would like to wish you all a very Happy New Year for 2012!
