Thanks for all your comments. I am using Outlook Express now. Originally I was just using WebMail/Horde and having the problem. I set up account according to TCH Help Site and changed port to 26 and still get error message when sending mail from .com address to ISP address. I've been a TCH account since May 18th. I do believe I can send mail to other addresses but I think I will double check. I suppose I don't really have a need to send email from .com to ISP since I'm using Outlook Express for both now. As long as I can send to others I'm good to go, I think. I appreciate all your help, because of your expertise I can use Outlook which is what I really like and wanted!
