I've got Qmail/VPopmail (5.2.1) running on a Slackware 9 box and I am unable to relay outgoing messages from any of our Windows/Outlook clients. However, I can relay from the Linux/KDE/KMail clients...
I've gone over the Outlook 2000 settings again and again, and I've also tried using Outlook express. Searches on Google haven't turned up much yet but I am still looking... I have also confirmed that I am not using SSL or any other secure auth for SMTP... I can't remember if I configured with --enable-roaming-users=y but I did find a #define POP_AUTH_OPEN_RELAY 1 in the config.h file which suggests that I did (that and the fact that everything works fine on the Linux boxes). I have set this server up by carefully following the steps outlined in "The qmail Handbook" by Dave Sill and I have tried in good faith to solve this on my own but I'm running out of ideas fast and could really use a push in the right direction this time... My only thought is that the Outlook clients are failing to auth on send and qmail defaults to the rcpthosts file... If I add the target domain to rcpthost and try again from the Outlook client, it works - but, of course, this is not at all the solution... David Benson Real Networks
