We have become aware that an increasing number of Internet Service Providers are now filtering port 25 (SMTP) in an attempt to combat spam. This has caused many of our customers to have problems sending mail and is the most common enquiry to the Cheeky Monkey Hosting support team.

For most customers, your Outgoing mail server (SMTP) setting is mail.yourdomain.co.nz - for example, if your domain name is monkey.co.nz then your Outgoing mail server (SMTP) setting would normally be mail.monkey.co.nz. However, error messages can be caused if your ISP does not allow you to send mail through another ISPs mail server such as Cheeky Monkey Hosting's. ISPs known to block port 25 include: Paradise, Slingshot, Telstraclear, Woosh, Xnet and Xtra. You can easily resolve this by changing your Outgoing mail server (SMTP) setting to your ISPs:

* Paradise (smtp.paradise.net.nz)
* Slingshot (smtp.slingshot.co.nz)
* Telstraclear (smtp.clear.net.nz)
* Woosh (smtp.woosh.co.nz )
* Xnet (smtp.xnet.co.nz)
* Xtra (smtp.xtra.co.nz)

For example, an Xtra user experiencing this problem may want to try using the outgoing mail server of smtp.xtra.co.nz instead of mail.yourdomain.co.nz. You will also need to turn off "my outgoing server requires authentication" in your email client. Please note that your incoming mail server (POP3) setting remains unchanged.
