email account settings

This overview summarize what you'll need to know in order to receive and send email using your trilithium.net account(s). Step-by-step instructions with screen shots are available for users of Microsoft Outlook and Microsoft Outlook Express. While Outlook and Outlook Express are popular and supported, we recommend against using these email clients due to their long history of security problems and other flaws.

For other email applications and experienced users, here are the relevant configuration details:

If the client software complains about invalid or untrusted server certificates, install the trilithium.net root certificate and make sure it's added to the list of trusted certificates. Most email applications will refer to a system-wide list of trusted certificates, but some applications keep a separate list which you'll need to configure manually.

Please don't configure your email program to check mail automatically more often than once every five minutes. Once every 10-15 minutes is frequent enough for most users, and checking mail very often puts unnecessary strain on our mail server. No limit is enforced; feel free to check for mail manually as often as you like if you're expecting important mail.

There's also a web mail interface available. It offers very basic functionality and is mainly intended for when you don't have access to your regular email client.

Encryption and secure email

Encrypted SMTP and POP3 connections are essential for protecting your account password and other sensitive information from eavesdroppers, which is why you need to use an email client which support SSL/TLS connections for POP3 and SMTP. All the common email clients have such support today (you can work around limitations in old software, but upgrading will usually be a better alternative).

Note that while the secure connections will protect information transferred between your computer and our server, there is no guarantee that messages you send are transmitted securely all the way to their final recipient. If you are sending sensitive information through email, we strongly recommend protecting it using software such as PGP or GnuPG.

Known issues

Some ISPs are blocking or redirecting outbound port 25 traffic. This means you won't be able to send mail over the standard SMTP port. If this affects you, use the alternate port 465 (SMTP over TLS) instead when sending mail.

Early versions of Microsoft Outlook (including the one included in Office XP) have problems with encrypted connections on port 465. Microsoft has released a fix for this bug; update your Office installation with the latest Service Pack if you have this problem.

If you are using Microsoft Outlook or Outlook Express and receive error 0x800CCC7F while trying to connect to the SMTP server, then it may be a problem with antivirus software scanning outgoing mail. Norton Antivirus in particular is known to not work correctly while connecting securely. To solve the problem, disable scanning of outgoing mail or use a scanner that works with your email software.
