To maximize deliverability, SkySwitch strongly recommends sending email via your own SMTP server or sending from a dedicated email service such as Mailgun, or Amazon SES, as documented here. On top of improving your email deliverability rates, these services often offer additional insight into mail delivery and opening statistics which can be helpful when troubleshooting email related issues. Alternatively, email can be sent directly from SMTP servers within the SkySwitch Hosted PBX Platform. This article describes how a reseller should configure the DNS records on their white-label domain to attest that SkySkwitch’s SMTP servers are authorized to send mail on behalf of the domain. At this time, SkySwitch does not offer DKIM key generation which could affect overall deliverability rates. However, deliverability can be improved by adding an include to your SPF Record.SPFSPF records allow the recipient server to verify that the received email was sent from an authorized sending server by authenticating a DNS SPF (or TXT) record after receiving an email.In order for mail servers to accept mail from your domain sourcing from the SkySwitch Hosted PBX Platform, you will need to add an include statement to your domains SPF (Sender Policy Framework) record. The additional include statement would look like this.include:_spf.skyswitch.comIf you already have an SPF Record you would simply add the include statement to the record after the “v=spf1 “ and before the qualifier such as “-all”.An example SPF record is below.v=spf1 ip4:75.98.50.0/24 include:_spf.skyswitch.com ~allFor more detailed information on SPF formatting please visit https://en.wikipedia.org/wiki/Sender_Policy_Framework
