Information on

Dear POP.CO.ZA user,

Posix has moved POP.CO.ZA from its own machine and put it onto the Posix Virtual Server - VWEB.CO.ZA.
Please don't panic.

This is to make way for our new Dell Blade server - lots more power, speed and disk. This will though take a few weeks to properly configure. The biggest advantage though will be a hugh increase in available disk space which will allow users to have e-mail boxes much larger than today and to also use the IMAP protocol for downloading your e-mail. But for now...

In order to read your e-mail online - please in future go to Please use this name so that the SSL Security certificate name matches. For Normal e-mail (that you download onto a PC) - please change the following settings on your machine.

POP3 Configuration

To configuration this in your e-mail client, you need:-
  • A User Name - usually your full email address (no changes)
  • Your Password (no changes)
  • The machine to connect to - please change this to

Most people will be using a POP3 connection and running on Port 110. SSL/TLS (security) support is NOW AVAILABLE. You can instead tick that box and connect on port 995. The server for e-mail purposes only has one SSL/TLS and the certificate uses the name which is why you must use that name if you are using SSL/TLS.

Mail may be left on the Server if you POP (read your) e-mail from more than one device, e.g. Laptop, Tablet and Cell Phone, but we recommend that you keep this to a minimum like 7 or 14 days. This setting is under Advanced or Extra settings.

  • Tick Leave a copy of messages on the server
  • Change Remove after 7 days
  • Tick Remove from server when deleted from "Deleted Items"

OutBound E-Mail Guidelines:

Traditionally, users will use the Mail Server of the ISP who they are connected to.
Some common examples of these are:-
  • Posix Capped ADSL: as per Telkom
  • Posix Uncapped ADSL: as per AfriHOST
  • Telkom: -or-
  • MWEB:
  • Cell C: -or-
  • iBurst:
  • Vodacom:
  • AfriHOST:
  • Axxess:
This single setting is placed in the "Outgoing mail server (SMTP)" box. This service runs on SMTP Port 25 and is not encrypted.

This is fine if your PC is used in one location and thus always connected to the same network provider, otherwise you'll be changing the settings everytime you move to a different Internet Connection.
If you are always moving about, swapping Internet connections, travelling both locally and internationally, then you should opt to use the Mail Submission option for your e-mail account. Once setup and working - it will never need touching again. In this case, outbound e-mail is sent to our relay server. For this to work, you provide your username and password details to authenticate yourself.

SMTP Mail Submission settings

You will find these under Advanced or Extra settings.
Typical settings are:
  • Outgoing mail server (SMTP): (though will continue to work for a few months)
  • You may tick the encrypted SSL connection (make sure you are using the correct name from above)
  • Tick Outgoing SMTP server requires Authentication (your username/passwd combo)
    • Tick Use same user settings as for fetching e-mail
  • Change Outgoing SMTP server on port 587 (and not 25)
  • Select Encrypted Connection type is TLS (choosing from None, SSL, TLS and Auto)
You must also set the SMTP Authentication (SA) flag to 'on' or 'yes', so that the relay server accepts your e-mail. This is done on the VWEB site where your e-mail details are stored. You can login to using your e-mail address and password.

Security considerations

By using the Sumbission settings ( and using SSL/TLS for Fetching e-mail, all e-mail traffic between yourself and Posix will always be encrypted and your username/e-mail address and password hidden from the world. In addition, Posix also uses a technology called DANE so that emails between our server and other servers around the world always uses encryption when offered - again - keeping your e-mail as private as possible.
