I have a Java app on my webserver connecting to my mail server that needs to use the mail server to send msgs to people that sign up. The mail server seems to be working fine has smtp pop3 and webmail running. But when the Java application connects I get Oct 14 00:01:39 mail postfix/smtpd[15447]: connect from li53.members.someserver.com[69.164.*.*] Oct 14 00:01:39 mail postfix/smtpd[15447]: lost connection after UNKNOWN from li53.members.someserver.com[69.164.*.*] Seems like I get the same errors from IPAD and IPHONE the Java developer is telling me anyway. Is anyone familier with this problem?
