Cannot send email... ESMTP server temporarily not available message
I am a former xfinity subscriber that kept my email address. I access my email through Thunderbird and recently I started to get this error message when I attempt to send messages --
An error occurred while sending mail: The mail server sent an incorrect greeting: resomta-ch2-15v.sys.comcast.net resomta-ch2-15v.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available, please contact support.
I have ensured that the outgoing email password is correct and I have even deleted the password and resubmitted it which allows the system to send messages for a day or two then returns back to this error message and the email does not send. What else can I do to prevent this issue?

@OSUFan2000 Appears the issue is referenced directly in the error message you received. There is an instance failing authentication. Meaning a wrong password. Due to this the server placed an automated block on connections. This can be resolved by resolcing any issues in configuration with devices linked with the email account. (this means anything from email clients, security systems, log reporting systems, etc.)
I'm sending you a PM to get more information and see if I can find anything else for you.

If @ComcastCSAEmail or another employee doesn't reply to your message here, Comcast Security Assurance should be able to help. You can reach them at 1-888-565-4329 (from https://internetsecurity.xfinity.com/help/report-abuse/). Note that this is NOT one of the general customer service numbers.
The first-line reps there are sometimes not very helpful, so you may need to be persistent and keep at them until you get a satisfactory answer.

I have a similar issue that occurs every two days. Once I change my password, update my outlook password, all is well. When I receive the failure message, I start over. So every two days I have to reset my password. Why? No one in customer support nor technical support has been able to correct this. Yesterday was day 12. Six different passwords.

Thank you. I figured it was something like that. Guess I’ll have to figure out what app or program is doing this.

I have this problem too and it's been going on for weeks. I've changed my password multiple times, never helps. I can sent one e-mail a day until I receive the message:
An error occurred while sending mail: The mail server sent an incorrect greeting: resomta-ch2-09v.sys.comcast.net resomta-ch2-09v.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available.
Can someone please help me with this? I called the number below but they were unable to help. There is only one device associated with that e-mail account.

I have been having this same problem for months with my Outlook 2016. Outgoing emails are stuck in the outbox with the "excessive fail authentication". The only fix I've found is to reset my modem, then all emails are sent. Comcast says since I can send/receive from the Xfinity website, it is not a server problem. All my Outlook settings are correct for my POP account. After I reset my modem in a few minutes, the Outlook emails will be sent. Of course, MS says I should get MS 365. I can send emails for several hours after a modem reset. A new modem had the same problem, so not a modem problem. If is with Xfinity server somehow.

Maybe I'm selecting the wrong icon. None of these people show up in the Comcast list. [Edited: "Personal Information"]
