Who is the Systemadministrator?
It appears to be kingfilou! 🙂
Hmm, seems there directions differ...
Enter the number 587 into the "Outgoing server (SMTP):" field.
Click "OK" then "Close".
... set up to use SMTP authentication. You can now increase the security level, and transmit your e-mails via an SSL encrypted connection. The SSL (Secure Socket Layer) protocol makes the data stream "tap-proof".
You must make the following settings:
Incoming server (POP3): pop3s.bluewin.ch
Outgoing server (SMTP): smtpauths.bluewin.ch
... enter the number 465 into the "Outgoing server (SMTP):" field. Check the option "This server requires an encrypted connection (SSL)".
Type the number 995 into the "Incoming server (POP3):" field. Check the option "This server requires an encrypted connection (SSL)".
These directions are foe Outlook on a PC, but should be the same for you...
