Not being able to send emails really is usually caused by one of these five problems:



1. Not having the full email address in the box if it pops up asking for password.
Correct by putting full emailaddress@yourdomain.co.nz in the box.



2. Incorrect password

Correct by logging into your cpanel and go to Mail / Add Remove Manage email accounts and reset your password.



3. Incorrect Authentication Settings
e.g. In Outlook Express
Correct by going to the Tools menu

Tools > Accounts > Properties > Server

And under the servers Menu it should not have

Login Using Password Authentication, SHOULD NOT BE CHECKED

But check this one instead: My Server Requires Authentication SHOULD BE CHECKED.



4. Your ISP blocking port 25

e.g. In Outlook Express

Correct by going to the Tools menu
Tools > Accounts > Properties > Advanced

Change the outgoing port number from 25 to 26



5. Your ISP is on a Spam Blocking list.

Correct by letting us know your ISP's hostname and we will attempt to whitelist them for you. Please contact us for extra help.
