HI everybody... I have a recently new server installed with virtualmin GPL and have this problems...
sometimes some emails are not sended really to the recipients address (local and external emails..)
my postconf is

there are somenthing extrange in this info?
I have a server with 3 gb of ram and have 72 users using it...
pls could you help me to diagnose what is the problem?
