I herewith explain a few important things about email and relevant settings.
Cc or bbc:
If you send the same email to multiple recipients and just one of the email addresses is invalid in most cases NONE of the recipients will receive an email. (It’s still ONE email and if the system holds this email back because of an error it affects ALL the recipients)
The solution is to make sure all email addresses are correct, to send an email to each recipient individually or to make use of a program designed to send email to a group such as a newsletter system etc.
POP3
The pop3 setting on your email program indicates FROM WHERE your email program must check for and fetch email. This will always be the POP3 server where your domain / email are hosted.
In this case your POP3 will always be either the IP address of the server or mail.yourdomain.com
SMTP
The SMTP setting indicates TO WHERE your email program must SEND email for delivery.
1) You can use the same details as above. Either the IP address of the server or mail.yourdomain.com
xx: In this case you must select “My outgoing server requires authentication” and select “Use same login details as incoming email server”
2) You can also use the SMTP details of your internet connection such as smtp.dsl.telkomsa.net, smtp.saix.net etc.
IMPORTANT
As a general rule you must always be LOGGED IN when you send or receive email.
With receiving of email the system login for each email address individually. With sending of email the system login EITHER individually (xx above) or globally per internet connection.
If you use (1) above the system will send the email to our servers that will forward it to the recipient provided that you logged in with the same username and password. (Hence the setting in xx)
If you use (2) you don’t use our servers to send email and send it to the server as per your SMTP setting.
From this point it is now however important to take note that your internet connection must MATCH the SMTP server.
If you use Telkom ADSL and SMTP server setting is smtp.dsl.telkomsa.net it’s fine because you are already logged in (internet connection)
If you however now temporally connect to the internet with an alternative connection, for example Vodacom or iBurst, you are logged in at Vodacom or iBurst and not at Telkom ADSL so the smtp.dsl.telkomsa.net SMTP setting will not work,
VERY IMPORTANT
While it’s usually much faster to rather use the SMTP server of your current internet connection there are one important drawback.
Compared to the major ISP’s our servers have very few clients on it and we also tightly monitor spam and abuse so the change is VERY slim that our IP addresses will be blocked due to spam.
With for example Telkom ADSL there are a LOT of users that send a LOT of email and since they all appear to be from the same IP address (those of Telkom) it sometimes happens that such IP address is temporally blocked by major spam lists such as spamcop.
Due to above my recommendation is that you rather use our servers for both POP3 and SMTP. (Server IP address or mail.yourdomainname.co.za)
