Does anyone know what this means?
I am using Thunderbird on Ubuntu LTS. I got this message: <start> Sending of the message failed. An error occurred while sending mail. The server responded: impout008.msg.chrl.nc.charter.net cmsmtp <this was my IP address, the DHCP address assigned to me by Spectrum?) blocked. Please see <https://www.spectrum.net/support/internet/understanding-email-error-codes> https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1020. <end> The referenced site describes AUP#Out-1020 as <start> This email account has limited access to send emails based on suspicious activity. Blocks will expire based on the nature of the activity. If you're a Spectrum customer, <https://www.spectrum.net/contact-us> contact us to remove the block. <end> What is that "suspicious activity"? Is there anything I can do to find out what it is? Do I need to be worried about this? The "contact us" is just the Spectrum chat, which is unhelpful. If I talk to an agent, she says that they cannot help me and that I must contact Spamhaus. Spamhaus tells me on their site that if I do not have my own mail server (I do not), my ISP (Spectrum) must provide a request to unblock. Spectrum says they cannot help and I must follow Spamhaus directions (which are to contact my ISP). It appears that I am stuck in circular logic here. What's curious here though is that the IP address listed in the error message is my personal DHCP address provided by Spectrum, not the IP address of the Spectrum server. That seems strange because I do not run a mail server. My email should appear to come from the IP address of the Spectrum mail server. I once had a Spectrum engineer tell me that "all residential IPs are dynamic which are automatically listed on some blacklists. It is completely normal and would only cause issues if you are trying to host your own mail server, not just sending email through IMAP and it would definitely not stop anything from being sent through webmail. This would impact all of our residential customers if it were the case." Spectrum tells me they cannot change my IP address. But it is DHCP? Why can't they just terminate my DHCP lease and renew it with a different address? If I locally kill my DHCP lease, and renew it, I just get the very same IP address again, not a new one. -Mark
