Email System Setup on Computer

Every email program (Outlook, Windows Live, Thunderbird, etc) is different on how they set up email service, but they ask all the same questions. Here are all the answers that you need.

  • both IMAP & POP3 work

  • mail.semo.net for incoming

  • mail.semo.net for outgoing

  • your username is your email address

  • YES or NO on SSL for incoming & outgoing (see below for more information)

  • leave incoming server port to the default

  • change the outgoing server port to 587

 

Here are more details

SSL or no SSL

If you turn on SSL, you will be prompted to accept our certificate (your device might even call it an “untrustworthy” certificate, but you can select to accept it). This setting has to do with how the email messages are transferred across the Internet from our server to your computer. With SSL selected, each message is encrypted as it travels across the Internet to and from our server to your device.

If you have SSL turned on, then a message will pop up asking you about an “Untrustworthy Certificate” – that is your device telling you that it cannot verify the certificate BUT since you know that the certificate comes from SEMO.net, then you can click to trust it.

If you do not want to trust the certificate, then you will need to uncheck SSL and send your messages across the Internet unencrypted.

One thing you should know is that by clicking SSL, this selection ONLY sends the message encrypted to our server. That’s the first of three legs the message must travel:

  1. Your device to our email server
  2. Our server to their email server
  3. Their email server to their device

Often times messages sent from our server to the recipient’s server is not encrypted and the recipient’s email configuration may not be encrypted from their device to their email server. In other words, by checking SSL there are no assurances that your email message is encrypted until it’s intended target opens the message.

IMAP or POP3?

You can pick either one. We recommend IMAP because it will keep your phone email synced up with your webmail account. In other words, when you delete an email on your iPhone using IMAP, it also is deleted from your webmail account and vice versa.
