Rejection of outgoing email while in PortugAL
I am in the Azores, Portugal, for the summer once again. In previous years, I've had no problem with accessing full use of email through Thunderbird. This summer has been an endless string of error messages refusing to handle outgoing messages.
I regularly get this message: Sending of the message failed.
An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-c1p-023411.sys.comcast.net resomta-c1p-023411.sys.comcast.net CSI IP 89.114.65.170 is not permitted to send messages. Please contact support if you feel this is in error..
Clearly, this is in error, but I cannot contact Comcast to work with a real live person except by telephone, which from here would be quite expensive, even with my international calling plan.
I did switch on the VPN with my Norton 360 app so that I could access U.S. sites that do not comply with European Union policies. I have set up split tunnelling to exclude thunderbird.exe from the VPN. I have restarted my laptop many times. Now and then, Thunderbird works perfectly, but most times it will not allow outgoing email. Yes, I can use the website for sending email, but I manage four different email accounts (for several reasons, I must have separate accounts), and I can only log into the Xfinity website under one account for sending email. Cumbersome.
Nothing seems to work! More ideas I could try?

CSI in the error message means the IP is blacklisted by Cloudmark Sender Intelligence, an IP reputation service. Apparently that IP has been associated with spam or some other form of abuse. Please see https://forums.xfinity.com/conversations/email/cant-send-emails-from-pc-or-phone-app/602dafa5c5375f08cd12c06e?commentId=602dafb0c5375f08cd147870 for a discussion by @ComcastCSAEmail of how Comcast uses CSI.

@user_7d3661 Thank you for reaching out to the Digital Care Team. I hate to hear this has been your experience and would love to investigate this for you! Have you tried updating the settings: https://comca.st/3bSjkxM? Have you tried a different email application and had the same issue?

When I scrolled up to the top of the page, I did notice I'm under a new heading, so I guess I did get moved. OK, now how do I solve this problem?

Thank goodness for BruceW's post in this forum. After two calls with Xfinity support today including one with Customer Security Assurance who still wasn't able to help. I was able to go and chase down the actual error message I was getting sending off both my laptop and my phone when on WiFi and determined that my ISP who is well respected and doesn't have their IP addresses blacklisted hardly ever thinks one may have gotten listed with one indiv entity and thus Comcast/Xfinities servers wasn't allowing it to communicate with the email servers. One call to my ISP and they had the situation resolved in no time. Unfortunately I can't get back the time I spend on the phone with Xfinity who didn't seem to have any hint at this being a potential problem despite the troubleshooting we attempted on the calls.
Anyway I'm appreciative of these Forums and the folks who help here and am back to being able to send emails again! BTW the connection was the inclusion of the CSI in the error message which is how I found this forum post!!
