Avast Internet Security blocking QuickBooks 2017 email

Hi Everyone,
I have a client with a Windows 7 64bit PC.  They are using QuickBooks 2017.  When they email an estimate or invoice (using their Gmail account) it gets stopped by Avast Internet Security.  I have tried turning the AIS Firewall but estimates & invoices are still not allowed to be sent.

What exceptions in AIS do I need to add to permit estimates and invoices to be sent?

Is the Gmail account properly configured in QB?

You may also need to have Gmail configured to allow less secure apps, which can be done in the webmail interface. https://community.intuit.com/articles/1020487-set-up-gmail-in-quickbooks

Thanks for the reality check. Yes Gmail is configured correctly (less secure apps = on, etc)

@btan
I added the port exceptions to Avast Internet Security but still it did not work.
Frankly it's not worth continuing troubleshooting for me or my customer.  He'll just have to turn off all Avast shields for the duration when he sends estaimates/invoices directly from QuickBooks

Thank btan. I caught that and added the rules to AIS accordingly.
Maybe an alternative is to Uninstall AIS, reboot then reinstall. But it would mean additional $ for my client. But I am only going to speculate.

Ah. I looked at part of your wording incorrectly then. Try the reinstall and the exception, bit I have seen software where the was no choice but to replace it. McAfee firewall was a perfect example.
btan

Yes if exception and reinstall with exception doesnt work still then other host FW  can be considered. Not really wise to disable FW as user may conveniently forget to turn on it. Other alternatives include ZoneAlarm Free Firewall 2017 or Tinywall.

I ran into the same issue after updating my QB 2017. I (temporarily) fixed it by turning off the scanning of outgoing smtp emails in Avast. Go to Settings>Components>Mail Shield (click customize) and then untick "scan outbound mail (SMTP)".

It's more of a temporary fix I guess as it's not scanning outbound mail but at least incoming is being checked.

Probably uninstall and reinstall AVAST may help to isolate. If there is no changes to rhe port for SMTP, it should not be blocking.(i.e. SSL/TLS encryption to 'None', ports for SMTP to '25', for POP3 to '110' or for IMAP to '143', by default). Nonetheless, trying out other firewall can still be considered.

As we've cited, if you really want to keep scanning outbound email, then you're going to have spend time trying to pick apart the mail rules of Avast or to look at other software. However, we cannot guarantee that it'll work the way you want it to either. I want to say that ESET would work with it, but I forget whether the clients I had at the time actually used the email functionality of QB. You can remove Avast and try a trial of a different product.

If you want to keep Avast, then you're going to have to show us the mail rules in Avast.
