Hi, I'm new to Linux and IT in general, my problem is proper configuration of outlook express or proper configuration of ispconfig so clients can send and receive email. My OS is openSuSe v.10.2. I used the How-To tutorial to install ispconfig and used How-To tutorial for “setting up your own Name Server and proper config of Go Daddy” to resolve Name Server issues. Everything else checks off; my ftp, web server, name server / dns daemon, mysql ,port forwarding issues and according to ispconfig all services are currently online. Using both dig and ping command-line functions, mail.mydomain.tld possess a status of NOERROR and no packet loss. Currently no web mail is installed, but when I tried to connect with the mail server using Microsoft Outlook express I get an error message stating that; “Task ‘pop.mail.mydomain.us’ the server name you entered can not be found on the network”. It appears I’m able to send email to this server at email address firstname.lastname@example.org , only because I don’t receive an error message from Yahoo mail server stating that the mail recipient was unreachable. My current settings in Outlook for: Incoming mail = pop.mail.mydomain.tld Outgoing mail = smtp.mail.mydomain.tld Dig and ping indicates all is good concerning hostname ‘mail.mydomain.tld’. Any help would be appreciated, Thank-you.
