resomta-c2p-555953.sys.comcast.net resomta-c2p-555953.sys.comcast.net ESMTP server not available (396356/136.144.35.123)

I've a history of difficulty using my VPN while accessing my email. Email is fine without the VPN. This particular event has occurred after nearly a year of being solved. In the past I've had to change my VPN server to restore 24h interruptions. This past technique no longer works - regardless of my VPN server the event outcome is the same. My credentials on my computer local have remained unchanged for certainly the past five years. My mail client is MS Outlook. Appreciate any guidance to resolve this inconvenient situation. Thanks.

user_e45kle I would advise trying a different paired VPN server. There should be no issues with VPN and email. A common workaround is to use split tunneling to exclude email traffic from the VPN, or to check the Outlook connection status for specific errors. Your Outlook profile might be configured to look for the mail server using a local name that isn't accessible through the VPN.

Thanks for the follow up. I've tried 1) using my POP account from different servers in US, 2) POP account from Canada, 3) just created an IMAP account and still cannot send email without disabling the VPN. My VPN supplier is ExpressVPN, I've used them for years. I have no access to another VPN supplier at this time. The error message with IMAP is virtually the same: "resomta-c2p-555920.sys.comcast.net resomta-c2p-555920.sys.comcast.net ESMTP server not available (396356/136.144.43.96)" I simply cannot reach the ESMTP server without disabling my VPN for the mail sends. Going to revert back to my POP account because that is where I've interacted with Comcast since the very start, decades now. This error message is new, especially the "ESMTP" - used to be simply "SMTP" but that was fixed.

The concern is not "accessibility / disability" help related............ Topic moved here to the proper help section.
