Sending email problems

[64bithost]

So. I just got the latest 11.0.9 version of Plesk and I am having problems sending email. But the problem is with random accounts not in bulk. If I create a domain at DOMAIN.COM, four of the six emails will have the ability to send two will not. I am configuring them like this

username: johndoe@domain.com
password: justtryme

inbound server: mail.DOMAIN.COM
outbound server: mail.DOMAIN.COM

so all six should not fail.

Any recommendations
Chris

Since you are using outlook, what error does outlook spit out? Also, if you are using Postfix, try enabling TLS authentication for SMTP
