Thunderbird - Can't send or receive emails

more options

Hello,

I have not been able to send or receive emails for the past 4 days using Thunderbird.

Before I went on vacation on Friday 22nd September 2023, I was able to send and receive my emails on my wendyp@wn.com.au address using Thunderbird on my computer. Since I got back on Monday (25th) I have not been able to send or receive any emails. Nothing has been changed in the Thunderbird settings.

At first, I thought Thunderbird might need to be updates. I did an update, to no avail. Current Thunderbird version is 115.2.3 (64bit). My computer is running Windows 10.

I use Bitdefender for protection and I turned off the virus and firewall to see if that helped, but it didn't.

I don't believe it is my actual webmail server, as I have been able to get my wendyp emails through my Android phone and by logging into my webmail account. I have also been able to send emails, with no issues using this method as well.

The strange thing is, I have another email address (page3@westnet.com.au) on the same Thunderbird program on my computer, and that one is having no problems whatsoever. Again, both settings have not been touched in the past few days.

Please find attached screen shots of the alerts from my wendyp@wn.com.au account.

The first attachment is when I try to request new emails from the server on Thunderbird.

The second attachment is when I try to send an email using Thunderbird.

The third attachment are my wendyp@wn.com.au email settings, which I have not changed at all.

I hope to hear from you soon, so this can be rectified.

Thank you - Wendy Page

Your picture shows the settings for the incoming POP server with connection security = none, and I assume it's the same for the outgoing (which is why the error is 'relay denied'). According to their site, you should be using secure settings:

incoming POP server: mail.westnet.com.au port: 995 Connection security: SSL/TLS Authentication: normal password User Name: email address

outgoing SMTP server: mail.westnet.com.au port: 587 Connection security: STARTTLS Authentication: normal password User Name: email address

I changed the secure settings using both choices (SSL/TLS and STARTTLS) with no success. I even turned off my Bitdefender firewall while experimenting.

As I mentioned, I have not changed the settings in Thunderbird at all. And what doesn't make sense is the other email address, which is on the same Thunderbird program as the problematic one, is having no issues whatsoever AND the settings are exactly the same. The only difference is the wendyp uses "wn" and not "westnet". The "wn" is because it's an old Westnet email address.

I have been able to get into my webmail on my ISPs website, and send/receive emails on the wendyp email with no issues. Hence the reason it has to be Thunderbird.

I've had these settings on Thunderbird for many years and had my email address for decades. I don't understand what has changed.

There was a recent issue with a different provider (Optimum), where users with non-secure settings were suddenly unable to send or receive. Changing to the recommended secure settings fixed it.

The fact the account is working in webmail is not relevant to its performance in TB, as the two use different systems.

I suggest you contact Westnet to confirm if your non-secure settings are still supported. Also, try running Windows in safe mode to test if Bitdefender is interfering with secure connections. Disabling BD is not sufficient to rule out its effect.

OK. Will do. Thanks.
