E-Mails not sent, only transferred to local outbox

[satosti]

Hi there,

after a fresh install of Thunderbird 78.11.0 (64-bit) on a Windows 10 laptop, Send Later seems to be broken. At the scheduled time messages are being copied to the local outbox folder and deleted from the drafts folder. They are, however, not actually being sent.

I'm pretty sure its an issue with a setting, but I can't figure out which one. Any help would be great!

Here is my troubleshooting information:

Hi there,
Thanks for your patience. I don't see anything obviously wrong in your settings. I need a little more information about what's going on. First thing to check would be whether the outbox is working at all. When you have a chance, please try the following and let me know the outcome: With a message in your outbox, can you use File > Send Unsent Messages to send the messages?

[satosti]

Hi Jonathan,

thank you for your help! I'm not quite sure if you prefer to be chat via e-mail or on github, therefore I'll copy what I've sent you via e-mail here.

With a message in my outbox, the File > Send Unsent Messages feature works perfectly in Thunderbird. As does Send Later when installed in a portable version of Thunderbird, up until I copy over my prefs.js from my full installation. It is somehow connected to one or more of the following mail-account settings inside the prefs-file:

mail.server.*
mail.smtpserver.*
mail.root.*
mail.identity.*
mail.account*

I wasn't able to figure out which of them causes the issue, but as soon as I copy those over from my installed Thunderbird, the described behavior ensues. Do you have an idea which of these types of settings could cause my problem?

[jph-sendlater]

I'm not sure what to suggest, except to attempt adding one account at a time until things stop working. If anything, I would advise against copying prefs.js directly from one profile to the other, since there might be subtle differences between the two Thunderbird builds. It would be safer to setup the preferences in your new profile from scratch to match the originals.

[satosti]

The accounts were added consecutively during the initial full installation, but for some reason I still ended up with user_pref("mail.accountmanager.defaultaccount", "account2"); in my prefs, which causes the issue with Send Later.

I don't know in which way the defaultaccount matters, why it was set to "account2" or why this breaks Send Later, but changing it to "account1" fixed the problem. Perhaps someone more familiar with this setting would like to explain this for future solution seekers. The problem itself is now finally solved.

[jph-sendlater]

I also don't entirely understand what the defaultaccount preference does, but I have encountered something similar before (e.g. #292 ). In that case it also prevented the manual "File>Send Unsent Messages" button from operating. The mysterious thing in you case is that the manual method worked, but send later still wasn't able to operate 🤷

Anyhow, the solution is updated in the docs now. Hopefully this simplifies things if another user encounters the same issue in the future.

[satosti]

Change
user_pref("mail.accountmanager.defaultaccount", "account2");
to
user_pref("mail.accountmanager.defaultaccount", "account1");.

[jph-sendlater]

Excellent, I'm glad to hear you've solved it! I'll add a note about this to the documentation.
