Firewall blocking mail

[REDACTED]

Hello all,

We are currently having a problem with my dad's laptop and ofc I'm the one to fix it 

Anyway, it turns out the Avast Premier firewall is holding back all incoming and/or outgoing mails (checked in Win10 mail and Mozilla Thunderbird)

When we try it on our desktop (running Avast internet security) it works like a charm..

If we disable the firewall on his laptop, it also works.. So it's definitely a problem with the firewall of the Avast Premier.

Any help or info would be appreciated !

Thx

If still problems, delete all firewall rules related to Win10 mail and Mozilla Thunderbird
Reboot and create new rules when/if firewall ask

Hi there, apparently it was set up in public mode.
When I changed it to private, it worked ! So I'm changing it to private, and unchecking the automatic profile switch option..

Thanks !
