Forum zhromadźenstwa Thunderbird za Android

Hello, Not sure if my first post was published.

Over the last week non of my mails was sent to the SMTP server. I uninstalled the account to start over again.

Upon configuring the mailbox account, the MAPI step was successful.

However, configuring the SMTP server, I am receiving an error: Unexpected end of stream (view image) What is the solution?

Been using Thunderbird for Android for many months for the email accounts I have with my ISP [optonline.net]. Several days ago sending of emails began failing. Error messages appearing in my Android Notifications say, "Failed to send some messages" "Sender refused". This is happening on all 4 of the devices my wife and I use. 2 phones and 2 tablets. Optimum is blaming Thunderbird. Thunderbird is still working fine on my Windows computer. It seems that all info regarding turning on Troubleshoot mode is referring to the Windows version as I can't find the "Help" menu item in the Android version anywhere. I have reconfigured the accounts in Thunderbird multiple times. The setup of SMTP always seems to end clean with a message of "Settings saved". It seems to me that Thunderbird is getting some error code from my ISPs mail server and I am hoping to have some more info to share with their tech support. The version if Thunderbird for Mobile we are on now is 9. I noticed that version 9 was just released on 5/5/2025. Not sure when exactly version 9 was pulled down to my devices. My phone is Android version 10. My tablet is Android version 14. Both are having the same exact issue. Is there a Troubleshoot Mode in the Android Thunderbird app? Is there a log file that could shed some light on the problem? Just tried the Beta version. Same problem. Also tried versions 8.2 and 8.0, Same problem. I still think that it's on Optonline.net but I'm going to need to do their job for them and find the reason it's stopped working. They are just going to blame Thunderbird. [and yeah, I tried K-9 as well]

I have a daily email that shows me images of my incoming mail pieces. However, in Thunderbird for Android, the images are always broken. I can't figure out settings to correct. Feature works fine on a different mail client. Anyone got any clues?

Hi, How come there is greater than and less than on each side of links in mails in Thunderbied for Android? Can they be hidden somehow?

Thank you in advance.

In composing? Just like the chain icon shown just above where I am writing here. I checked and my format is html. I highlighted a word + looked on the menu there. Come to think of it, I see no way to bold text or other, typical html stuff I do on desktop TB all the time. I must be missing something.

Hi. For a long time, I've noticed that emails I send from home are sent, but those I try to send with the same settings do not get sent when connected to the Internet in 4 out of 4 cafes. My ISP, Zen, hasn't been able to explain why. I've tested whether Google VPN blocks it somehow, and it doesn't. I normally use Thunderbird. Today, I found that, in the same cafe, messages I tried to send using Thunderbird failed to send, whereas there was no problem with GMail, Proton Mail or Outlook. Any suggestions?

Hi ,

Is Thunderbird for Android capable of searching emails that are very old and on IMAP server but those are past the download period.

For example: If TB downloads only 30days email data on my mobile app, can i search my email which is say a year old and still present on the IMAP server but not withing the phone data.

This is a very important feature. If TB Android doesn't support this function, the can u suggest any other app that support this feature.

An issue I have just noticed is that when I send emails they weren't getting copied to the accounts "Sent" folder despite the box to request this being ticked. I have now discovered that on another settings page it had the "Sent" folder set to None and I had to explicitly associate "Sent" with the sent folder in the account before emails were copied. It would be helpful if when ticking "copy sent emails to sent folder" there was a warning if it was associating "Sent" with "None".

Just had a couple of issues with sending emails from Thunderbird Android ... I don't tend to send many emails from my phone so didn't notice the issues for some time!

A few weeks ago I ended up changing my email server's password - I updated my PC Thunderbird to reflect the change for incoming and outgoing servers and then thought I did the same on the Android Thunderbird - but I only changed the password for fetching - perhaps missed the sending password as in the Android version its in the account menu rather than a separate "outgoing server" menu item.

Everything seemed ok as I got emails on my phone but yesterday someone complained I'd not replied to some questions and I was sure I'd replied to their email. Looking on my phone today I noticed that there were a handful of unsent messages (including this reply) in the Thunderbird Outbox.

Basically when I sent each message the connection to the outgoing server failed due to the now out of date password but instead of giving any warning that the connection had failed it had just silently moved the message to Outbox where it remained as the outgoing server connect attempts would continue to fail. Having some form of warning that server connections were failing due to incorrect password would be useful - I think the Windows version will ask for a new password to be entered if a login with the current one fails. Note: the checks when setting the password means you cannot configure the account with a password that fails but if the password changes you get no warning

I have many accounts + like to hide accounts on the sidebar. I know I can cycle thru the accounts by repeatedly tapping the account name at the top of the sidebar. But my list is long. Can I long-press the account name + get a popup to select directly,

Like many, I have multiple accounts set up in TB. When I use the left sidebar and select a different account why must I either manually swipe the sidebar away or tap a folder to make it retract? Seems a bit painful.

Wenn ich eine lange Mail habe, oder schon mehrmals auf Mails geantwortet wurde, befindet sich ein Anhang immer ganz unten an der Mail, das ist oft sehr lästig. Wie kann ich einen Anhang in einer Mail unter den Betreff anzeigen lassen?

in english... If I have a long email or have already replied to emails several times, there is always an attachment at the bottom of the email, which is often very annoying. How can I display an attachment in an e-mail below the subject line?

Thanks, Guido
