I am using Thunderbird 16.02 with Avast Free Antivirus 7.0.1473.
When I run Thunderbird and try to get mail, I get the following alert: “An error occurred with the POP3 mail server. Mail server incoming.verizon.net responded:”.
When I send email I get the following alert: “An error occurred sending mail: The mail server sent an incorrect greeting: Cannot connect to SMTP server 206.46.232.12 (206.46.232.12:587), connect error 10061.”
If I disable Avast!’s shields or set Avast! to not scan mail, I can send and get mail.
How can I get Thunderbird and Avast! to work together?
Following advice that I got from another website, I set Thunderbird and Avast! as follows. Except as shown, both programs settings are as installed i.e. “out of the box”.
Thunderbird server settings:
POP Mail Server (As installed, not changed)
Server name: incoming.verizon.net
Port: 110 Default: 110
User Name: mcetmc
Connection security: None
Authentication method: Password transmitted insecurely
Thunderbird Outgoing Server (SMTP) settings:
Verizon Online – outgoing.verizon.net (Default)
Description: Verizon Online
Server name: outgoing.verizon.net
Port: 587
User Name: mcetmc
Authentication method: Password transmitted insecurely
Connection security: None
Avast! setting are:
Avast! is set to scan inbound and outbound mail.
The Expert Settings SSL accounts are set to:
