User Settings for Sector Alpha's email servers
Inbound Server Settings
We have a few options for settings that can be used so I have formatted them as a table
| Protocol | IMAP | POP3 | ||
|---|---|---|---|---|
| Server Address | sector-alpha.net (or alessa.sector-alpha.net) | |||
| Port | 143 | 993 | 110 | 995 |
| Encryption | StartTLS | SSL/TLS | StartTLS | SSL/TLS |
| Username | Your full email address e.g. username@sector-alpha.net | |||
| Password | Your email password | |||
| Authentication Method | Normal password (PLAIN) | |||
A unencrypted connection can be made for ports 143 and 110 but authentication isn't available until a secure connection is established and therefore neither is access to emails.
Outbound Email Settings
SMTP settings are
| Server Address | sector-alpha.net (or alessa.sector-alpha.net) | |
| Port | 25 | 6669 |
| Encryption | StartTLS | |
| Username | Your full email address e.g. username@sector-alpha.net | |
| Password | Your email password | |
| Authentication Method | Normal password (PLAIN) | |
| Standard SMTP port | Extra port to allow access if port 25 is blocked | |
I may be persuadable to enable submission (port 587) or the historic SMPTS (SMTP over SSL/TLS, port 465) but will need a good reason. Please talk to a server admin.
Both ports are unencrypted connections to start with that don't allow authentication.
- The server will accept email for local targets without authentication or encryption
- If StartTLS is used the connection is encrypted and then authentication becomes available and the server can be used to relay emails.
- Authenticated users can send emails with any from address and to any address but an invisible header is added to mark which user was authenticated to the server
Anti-Span/Virus settings
We have anti-spam and anti-virus on inbound emails using SpamAssassin and ClamAV. ClamAV is regularly updated. We also run a shared Bayes filter for SpamAssassin. To teach spam and ham (not spam) messages to the filter create folders called Learn/Spam and Learn/Ham (case sensitive) in your imap Inbox and place emails in them. Spam emails will be automatically deleted after learning. Ham will be left for you to remove at a later point. The filter learns at 3:23 Europe/London. If you have any problems please talk to a server admin.
Advanced Features
If you don't want a seperate email account we can instead setup the server to forward emails to another (external or internal) address. Our email server also has options to forward "tagged" emails to specific folders in your inbox. For either of these options please talk to a server admin.
