Hello,

I have a problem with qmail-qmqpd compatibility between qmail-ldap and
postfix 2.10.2.2z with the following error in postfix'es log:
"netstring format error while receiving QMQP packet header"

I thought that qmqp is compatible between qmail-ldap and postfix isn't it?
Is it any chance to fix the problem?

Best wishes,
Gennady.
