App

Thunderbird for Android

App version

8.2

None

Android version

Device model

Redmi Note 13 Pro 5G

Steps to reproduce

Hi all,

I have installed Thunderbird Android and correctly set an IMPA account. It is not a "provider" email (eg, Gmail, yahoo, etc), it is my own email using my domain+provider.

I am able to receive emails, no problem there. But I am not able to send any email.

After I tap "send", emails are moved to the "sent" folder, but they are never delivered (they don't go to spam). I have also checked the settings with my provider, that hosts my email, all is correct.

Additional context.

• If I send an email to myself (same from/to email address), that is sent.
• I have tried K-9 with the same settings, it doesn't work neither.
• I have tried FairEmail and BlueMail apps with the exact same settings, and YES emails are correctly delivered using those apps.

Thanks

Expected behavior

Emails should be sent using my custom email+hosting

Actual behavior

Emails are moved to "sent" folder but they are actually not sent.

Other apps like fairemail and BlueMail work well and send the emails (using the exact same setting)

Logs

Can you provide some logs? Is a connection to the server being established? Do the server logs contain any information? What email server is running? Could it be #6327 ?

Hi @kewisch ,

Thanks for replying to my issue.

As mentioned, I have an email account set manually as IMAP. It is an email address with personal domain, hosted on an external provider (bluehost, I hope it is not a problem to say it, but maybe it provides more context). Incoming/Outcoming servers are set correctly, I have also checked that with my provider.

When I try to send email, I don't get any error message and the emails correctly go to the "sent" folder. However, emails are not actually sent; I have tried sending to gmail, proton and tutamail addresses. If instead I sent an email to myself (same from/to address) then I get the email.

When I try to send an email, I don't get any validation/message from the app. When I send to myself (so I get the email) I don't get any "success" notification. When I try to send to external domains (gmail, proton, tutamail), emails are not sent, but I don't get any error notification neither.

As said, I have also set the same email address to other apps (fairemail and bluemail), following the exact same setting, and via those apps I am able to send emails.

I hope this helps! Massi

Bluehost and other providers from the same brand sometimes have issues, this is likely some interplay between TfA and Bluehost. Can you provide logs via https://github.com/thunderbird/thunderbird-android/wiki/LoggingErrors for the send process?

Hi @kewisch ,

I have enabled the debuggin in the app. Then I have performed the same task (send emai, email no sent) and I have downloaded the log.

Now, I am not sure if I should and how share the txt file, also because it contains personal information.

Please advice and thanks, Massi

You are welcome to XXX out the personal information and share it here if that works for you.

Hi @kewisch ,

I have attached the log file in this comment. I have replaced email addresses, in/out servers and IP with XXX.

I hope I am not leaving any other sensitive data in there, but if so, I would kindly ask you to remove my file (or let me know, so that I can remove it).

I hope my inputs would help fixing the issue.

Thanks! Massi
