I have a big problem: I have entourage 08 and I have 3 mail accounts on it. 1. is an exchange server (works fine anywhere) 2. another exchange server. But since you can only have 1 exchange account, I go throght the web interface as imap (mail.companyname.com). 3. is just my yahoo account. So here is the problem: I can send and receive emails just fine while at my office (wireless). But at home I can only receive emails from accounts 2 and 3 and I cant send. At home, I have both, cable and DSL both with their own wireless routers that and both experiance the same problem. I also have an Iphone and I just tethered to my macbook to test my connection and I CAN send mail while tetheard to the Iphone. Anyone know what I have to do on my routers at home or anything else I should do?
