avoiding your emails being tagged as spam
Whenever an outbound message is sent from your domain through a server that is not officially associated (in your official DNS records) with it, there is a chance that the recipient's server will treat that message as a suspicious one and tag it as spam.
To avoid your Impactia routed messages being tagged as spam, a small configuration addition/modification is required to your external DNS entries.
If you already use an SPF record for your domain, simply add the following items to it:
include:impactia.com
If you do not use an SPF record, you need to create a new DNS record, of type TXT with the following content;
v=spf1 mx include:impactia.com ip4:external-ip-of-your-outgoing-mail-server ~all
The purpose of this SPF record modification is to confirm for any querying recipient servers that the Impactia servers (out2.impactia.com and out3.impactia.com) are authorized to relay email messages for your domain.
