Am I missing something ? My interpretation of the documentation indicates that the trusted network setting causes certain authentication and security checks to be bypassed if a computer is in the trusted network, and to not bypass those authentication and security checks if the computer is not in the trusted range. I see nothing indicating this setting will "forbid" anything... > I feel that Dovecot is slow.

I don't know about the reverse lookup, but this sounds like a caching issue to me. http://wiki2.dovecot.org/IndexFiles > > Thank you -- Computerisms Bob Miller 867-334-7117 / 867 633 3760 http://computerisms.ca
