Note: The VarAC team has only tested it with Gmail. We were unable to get it working with the Microsoft (outlook.com) email service. It may work with other SMTP email services.
Congratulations on joining the VarAC Email Gateway world!
Before you begin, we recommend creating a dedicated Gmail account for relaying gateway emails instead of using your personal account. This helps keep things organized and separate.
Now lets get started:
If you encounter this error, you'll need to enable 2-step verification for your account. You can do this by following this link: https://myaccount.google.com/security
Create a new app password. You can call it “VarAC”
Copy the password you got.
Go to VarAC settings screen -> Email tab
On the top left – Check the “Enable Email gateway”
Enter your Gmail email address.
Note: As some people tend to copy paste it, make sure you extra spaces are added before or after the email address.
Set the SMTP password to the “App password” you got from your Gmail account.
NOTE: Make sure you have no extra spaces as well. It is advised to remove all spaces from the password itself also.
Make sure the following are configured:
SMTP server: smtp.gmail.com
SMTP port: 587
Enable TLS is checked
That’s it. Click “SEND TEST EMAIL” and make sure you get a SUCCESS message. If it fails – inspect the VarAC.log file for details.
If you receive a "SUCCESS" message but don't see the test email in your gateway inbox (in Gmail), it may have been marked as spam. Please check your Spam folder and mark the email as "Not spam" to ensure proper delivery in the future.
Important Note: Some emails sent by gateways—especially those using newly created email addresses—may initially be marked as spam. As the email address builds a positive sending history, its reputation will improve, and services like Google will be less likely to flag it as spam. To help speed up this process, recipients are encouraged to mark these emails as “Not spam.”
