Hi,
I worked till 2005,6 with virtualmin, webmin usermin and sendmail and hat never a problem. Since a few days i have a new vps and webmin, usermin, but now is virtualmin installing postfix. Receive emails is working, but i can not send emails also not when i try to do it with usermin. My mac is telling the smtp server not relay. Have in between al 5 x installed everything new, after different changes please can you tell me what is wrong.?
With Kindly Regards
