How to use
Due to the restrictions at internet service provider level and our needs of properly working inbound and outbound mail services, we have configured a bunch of methods, to make domain names available from our own network.
This page tells how to configure your mail clients to communicate with those services.
SSL/TLS
Currently, no secure communications are available from Tornevall Networks. Everything you are doing will be sent and received in plain text.
Reading mail
You can get your mail in two ways: By pop3 or imap. The current configuration is listed here
| protocol | port | server | authentication required | ssl/tls available | ipv4-gateways | ipv6-gateways |
|---|---|---|---|---|---|---|
POP | 110 | pop.tornevall.net | YES | NO | 212.63.208.4 | 2a01:299:a0:25:25:25:25:25 |
IMAP | 143 | imap.tornevall.net | YES | NO | 212.63.208.4 | 2a01:299:a0:25:25:25:25:25 |
Sending mail
There are however moments where port 25 are also prohibited to use by your internet service provided and restrictions are made, so the only way to use SMTP are to use another server and port. If you have no other options, this is the method that we recommend you to use.
Be aware of the second relay, where port 587 is available. This is used, as a default plain text port, when the first option are unavailable for you - for example a restricted network, that do not allow communication through anything but standard ports.
| protocol | port | server | authentication required | ssl/tls available | ipv4-gateways | ipv6-gateways |
|---|---|---|---|---|---|---|
RELAY | 25 | smtp-out.tornevall.net (smtprelay.tornevall.net) | YES | NO | 212.63.208.6 | 2a01:299:a0::25 2001:470:dcb5::25 |
SMTP | 25 | smtp.tornevall.net | YES | NO | 212.63.208.6 88.80.19.161 | 2a01:299:a0::25 2001:470:dcb5::25 |
SMTP Authentication
Authentication are only necessary when using personal accounts outside the domains of Tornevall Networks.
It is still possible to get whitelisted here, so no authentication are needed. However, this is limited to static connections, with IP-addresses that are never changed by your ISP.
Examples on non static addresses are such hosts that are delivered by Telia, Tele2, Telenor, etc.
The authentication is always the credentials you are using to read and write mail via tornevall.net
