It listens on port 587 and is set to accept mail only from the app server IP address I gave the connector anonymous permission and used the Exchange management shell to give the new connector permission to relay. It worked for a while last night and then refused connections. I then ran Ghostmail on the app server. When sending through the new connector I get a 550 5.7.1 client was not authenticated. Rebooted the Exchange server this morning. No mail is being sent from the app server. I was able to send mail with Ghostmail through the new receive connector. About an hour later I tried to send mail and get 550 5.7.1 client was not authenticated. Any suggestions appreciated. --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
