Do you offer a SMTP relay server for outbound mail? What are the settings?

  • Updated

Right now, we don’t currently offer any email services - our focus is on delivering high quality internet services with no costly frills or add-ons. In the future, we may offer a SMTP relay service or mailboxes, though, and if this is something you’d like to see, please drop us a line via our live chat and let us know!


In the meantime, we recommend that customers looking for a SMTP relay for outbound mail use a 3rd party service such as Sendgrid (which offers a free trial, and generous free daily limits).


To set up Sendgrid with your scanner (or other device), sign up for a free account at and then generate a new ‘API key’ from Note down the generated key as it will only be shown once.


Next, configure your device to send emails using the SMTP address, with username apikey and the API key as your password. SendGrid accepts unencrypted and TLS connections on ports 25, 587, & 2525. You can also connect via SSL on port 465. Note that Pentanet do not currently block any of these ports outbound.
