Help Listers, You may recall I posted a question titled "Steps to install a new Server". Well we put that server into production this weekend and now I get to fight the fires. In recent testing I discovered that emails going out to my yahoo.com email address are not being received, but emails sent to my charter.net email address are!?! Any suggestions on what I should look for? I looked in my DNS table and I see no problems. I have an external webhosting company - acomhosting.com and we did have email going through their site, in fact my users still have the POP3 definition in their Outlook setup, but it is at the bottom below our Mailbox. Why one SMTP email client and not another? John Technology Applied
