I can no longer send mail from my Thunderbird POP.Gmail account. When I try to do so I instantaneously get an Alert with the following message: “An error occurred while sending mail: The mail server sent an incorrect greeting: +OK Gpop ready for requests from [my IP address] ]k16mb102005795ool”. (The numbers following my IP address always vary). I can receive email at this address, but I can send nothing. I have several more email addresses on Thunderbird (all through Gmail) and they work fine but they are all IMAP. My POP incoming port is 995 and the SMPT output port is 465. My ISP is Spectrum. Can someone please help?
