Thunderbird Trouble


"Sending of password for user maplesyrup@noname.com did not succeed. Mail server mail.twc.com responded: [IN-USE] account is locked by another session or for maintenance, try again."

This is the error message I receive half the time when retrieving email from Thunderbird. It is very annoying. I am the only one using this account and no other devices are activated at the time. There is no pattern to this. I can then use my iPhone or iPad and have never had an issue like this so it's not at the server end or a problem with the password or maintenance.

thanks

Have you tested with another email client, perhaps Claws or Sypheed?

Also, you have provided relatively little information. Is this a POP or IMAP account? Is it SSL/TLS or not? When you get that message, can you ping or traceroute the mailserver?

this is more likely to be an issue with the mail server than with TB, IMO

Is mail.twc.com the actual mail server to which you are connecting?

You are correct. I downloaded and installed Claw and the same thing just happened. Never had this happen with that bad word Windows Thunderbird but using Linux I do.

Not sure how I could check is mail.twc.com is the "actual" mail server when I connect. Know that is what is shown in the configuration. TWC was recently purchased by Charter and TWC is now called Spectrum. All I know now.

To add to this,,,Ten minutes ago I sent a picture on my iPhone successfully so maybe that had something to do with receiving another one of these messages of it being locked or down for maintenance or being in use.

All the settings as outlined above for POP are correct. There was one which was not checked and that was the SMTP Server requires Authentication. What does that mean? If not checked what happens?

When Apples default email program was open in the Apple iPhone 6s Plus and then opened on the Linux Desktop I would receive the message as outlined in my OP. With the iPhone being in the locked position I was unaware the phones email program was open. Upon closing the phones email program emails from my desktop, Thunderbird, could be received without the locked message. Not sure why this is but it is what it is!

Thanks

I'd say the SMTP setting change should not generate the error you get : SMTP is for sending mail, while you try to receive : other protocol and other server.
On the other hand, your initial message 'locked by another session' may mean that your iPhone was already connected, either retrieving the mail on the same POP server (which would be rather coincidental, but well) or even over the IMAP protocol, which basically can stay connected permanently.
I never heard about a server preventing simultaneous IMAP and POP retrievals in parallel, but yours may well be in that case...
Can you try to trigger a mail retrieval from your iphone and while it is doing this, attempt to connect with the linux machine?
Then switch the phone offline (or bluntly off) and try linux again?

That is very strange...I've never seen that before, either.
Maybe the next step is to contact twc/roadrunner support and ask them why this is happening.
I'd also be concerned that mail.twc.com has no MX record in DNS, but that would (might) only affect those sending email to you.

The box in the SMTP config just means you need a password to send mail. Most SMTP servers are configured to avoid spammers without the use of user passwords.

Do you have the email setup on another device like your phone? A lot of servers only allow one login session at once, so it could be checking at the same time as the phone is polling.
