Update 20th March 2015

Email Forwarders

This applies to clients who are forwarding emails to a domain outside of NZServers such as Gmail.

If you are doing this then we are asking you to stop doing this, as this is not a good idea or practice to use, especially if you use GMAIL.

Forwarders can cause massive problems because at this point and time they are not spam-filtered.
If you are receiving Spam then the forwarder will happy pass the SPAM to the forwarder.
If you set up a forwarder to a gMail/Hotmail/AOL account, it won't be long until email from the server has trouble reaching the mailbox, because they see our server as the source of all the forwarded spam, which is partially true.

No idea of what what this is all about?

If you think this applies to you please contact me at mike@nzservers.com

Forwarding works fine, until spam comes into the picture.

Sadly Spam creeps in. If your email address is well known then it's likely you attract spam.

 

Gmail

Since we are on the topic of GMAIL instead of Forwarding emails to Gmail you can setup GMAIL to receive emails from our server which is a much safer and better way of doing this - the following article will help you with this:-

Note we have assigned a secure certificate called secure2.nzhost.net.nz which allows you to use the secure ports for receiving email from Gmail.

Using Gmail to Receive Emails

Using Gmail to Receive Emails

There are many email clients out there. Wouldn't be nice to centralise all your emails in one place using your own email address by using GMAIL.

Email Passwords

We had several incidents where clients had loose passwords which allowed spammers access email A/C's to send large volumes of SPAM. The SPAM was stopped by changing the password.

If you have an easy password then change this immediately using CPANEL or by using webmail.

http://yourdomain.xxx/webmail. Please replace yourdomain.xxx with your own domain name.

 If you don't know how to do this please email me mike@nzservers.com

What are we doing at our end?

• We have added Barracuda to our RBL lists.

• We have also started to compile our own senders black list to reduce the volume of SPAM. This is a time consuming process as it will take time to build a list of known domains used to Spam through our server, which are not tracked through RBL lists.

RBL list means real time block list where each email received is checked against a SPAM list.

What are you doing at your end?

• If you are not using SPAM Assassin we urge you to activate this using CPANEL.

• We ask you to use the option to delete email marked as SPAM.

• We ask you not to forward emails to Gmail, AOL or Hotmail

• You can use email filters to block annoying SPAM using your CPANEL.

Port 25 being used for Email Clients

While this may have been true some years ago most ISP's are blocking the use of Port 25 to send out emails on.
The reason why is to stop SPAM being sent out on the IP assigned to the router and having this blacklisted.
If you use the configuration tool on CPANEL this may assign port 25 which you need to change.

Vodafone may still allow port 25 but ISP's like Spark have blocked this port.
The port you should be using for un-secure emails is Port 26.

On this subject you should be using port 465 which is a secure port to send emails out on and port 995 to receive emails for a POP3 email setup.

ISP Outages

On the 19th of March anyone using Vodafone may have experienced difficulties with our server as it looked like there were router issues.
We attempted to contact Vodafone - the lines were busy for too long so traceroutes were carried out which showed up the router issues.
There was no problem with SPARK.
When this happens the situation is out of our control.
People will still be able to send you emails and view your website but you may experience issues in trying to send emails.

The image below will give you an idea of the problems faced by Vodafone.
