How to Set Up/Modify DKIM for SMTP2GO
By default, all SMTP2GO users email is now signed via DKIM if you have not added a Sender Domain yet. Recipients of your emails will typically see emails delivered "via smtpcorp.com" or "via smtp2go.com". If you would like your recipients to see those emails deliverd "from yourdomain.com" then you will need to add that domain to the Sender Domains section of your SMTP2GO control panel.
The benefit to enabling Sender Domains for DKIM is that this change will allow your emails to be DKIM signed with your domain and will pass DKIM Alignment authentication tests, which are part of DMARC. MxToolbox recommends all senders should aim to DKIM sign email with their domain rather than using their vendor's domain.
