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.

Can I use encrypted links?

Yes! STARTTLS and simlar functions are fully functional as of july 2019.

Reading mail

You can get your mail in two ways: By pop3 or imap. The current configuration is listed here. On IPv6 all SMTP-out traffic goes via since the main provider is blocking their IPv6-roads.

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.

Outbound mail is currently thrown via yet another relay-server, as the main provider (smtp.tornevall.net) are rumoured as "bad sender" in some spamfilter-scorings (FYI, we are running this via DigitalOcean and their rumour as a spam provider is currently not very good). The decision to just relaying outbound mail though our own relays is  based on this. That's where smtprelay-1.tornevall.net comes in toghether with another failover-box hosted through GleSYS.

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

Spam filter

We use spamassassin running agains some RBL's. This includes both spamcop, uribl, dnsbl.tornevall.org and fraudbl.org, as a few examples. Antivirus amongst others is clamd and NOD32.
