How to clear a POP mailbox using Webmail

If your POP mailbox is full you can delete old mail via the Webmail interface. Download the how to document here

Note if your mail program is leaving read mail on the server that will fill the mail box up. POP mailboxes are limited in size and all email needs to be saved or backed up from your PC as it is not kept on the server. You should set the days your mail client leaves the mail on the server accordingly and this document will help with the setting.

SOS Support : Email problem : Ensure correct server settings

Please ensure that your PC email account server settings are NOT set as an IP address ( as that IP will be removed and you will no longer receive email from that server. Mail server settings need to be set as a NAME that is linked to your email address so for example:

 bob@sos.co.za will have BOTH the incoming and outgoing servers set to mail.sos.co.za, likewise fred@sosdns.co.za will need to have the servers set to mail.sosdns.co.za and so on.

 Please check and ensure that this is the case with your email settings to ensure you continue to receive email.

SOS Support : Email problem : Unable to send email but am receiving ok.

There is an understandable crackdown on mail sending via port 25 due to the proliferation of SPAM so if you experience this issue change your outgoing port from 25 to 587.

Account Settings > Change > More Settings > Advanced : Outgoing Server (SMTP): 587

We love Apple! The reason Apple is so awesome? The brand shows fanatical attention to detail, and Steve Jobs nailed it when he said: “Quality is more important than quantity. One home run is much better than two doubles.” “Details matter, it’s worth waiting to get it right.” “Be a yardstick of quality. Some people aren’t used to an environment where excellence is expected.” And our personal favorite: “I want to put a ding in the universe.”
