Dear iRedMail users,

I'm sorry to inform you that we have an incorrect setting in Postfix LDAP/SQL lookup file in iRedMail-0.8.6, and it exists in tutorial of upgrading iRedMail from 0.8.5 to 0.8.6. Please follow below tutorial to fix it:
http://www.iredmail.org/wiki/index.php? … 6-hotfixes

This incorrect setting returns empty transport for backup mx domain, mail cannot be delivered without a proper transport.

NOTE: This hotfix is applicable to below users:

*) users who upgraded iRedMail from old versions to 0.8.6 by following our upgrade tutorials before Jan 8, 2014.
*) users who downloaded and installed iRedMail-0.8.6 BEFORE Jan 8, 2014.

i repacked iRedMail-0.8.6 for downloading moment ago, so new installation doesn't need this hotfix.
