I updated my email password with comcast and now I can receive email but I can not send it.

K Mendall

Comcast/Xfinity forced me to change my email password. I entered the new password when prompted by Thunderbird. I am receiving email from my comcast email account. But anything I send from that email account shows this error: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-c2p-555442.sys.comcast.net resomta-c2p-555442.sys.comcast.net ESMTP server not available (9009/146.70.230.100)."

I've tried changing the SMPT port to 587 because an online search suggested that might work. The error message changed slightly but it will still not send.

Here are my current "Details of selected server": Description: Comcast Server Type: SMTP Outgoing Server Server Name: smtp.comcast.net Port: 465 Authentication method: Normal password Connection Security: SSL/TLS

When I click on "test connection" I get a green check mark and the note "Successfully established a secure connection to smtp.comcast.net:465.

What now?

Lts look at this error message you posted

"Sending of the message failed.
An error occurred while sending mail: Outgoing server (SMTP) error. 
The server responded:  

resomta-c2p-555442.sys.comcast.net resomta-c2p-555442.sys.comcast.net ESMTP server not available (9009/146.70.230.100)."

SO resomta-c2p-555442.sys.comcast.net resomta-c2p-555442.sys.comcast.ne is comcasts mail server which has generated the response.

ESMTP server not available (9009/146.70.230.100)."

This part tells us you are sending (ESMTP) and that the server is not available for some reasons that the server identified as 9009 and gives your IP address as 146.70.230.100

I have no idea what the 9009 means to Comcast of the server in question. but a quick google of the address shows https://www.netify.ai/resources/ips/146.70.230.100

It is fairly common in the USA for providers to only allow you to send mail if you connect to their servers from their network. Your VPN is not part of their network so I would guess you can not send mail unless you disable the VPN. The use of a VPN is a growing thing, but generally they do very little for the average user to improve their security but they do an excellent job of masking your geo location which means any service that relies on knowing it will have issues. Like your ISP mail and even google mail or Facebook et. al. but often you have a VPN to mask you geo location and a GPS location on the same device handing out your location to meters. Portable devices routinely use GPS to locate themselves and the user and will report that if asked the right way so you have to ask what the benefit of the VPN is to you when you elect to use one.

Windows offers enough bread crumbs that you and the device can still be identified even with a VPN. A VPN is not the panacea for anonymity most folk think they are. See this recent news article on identifying an offender despite VPN use, https://cyberinsider.com/microsoft-windows-telemetry-identified-hacker-despite-vpn-use/

If the FBI can do it, so can just about everyone else.
