What are the memory limits for Thunderbird. Currently, I get this message when I try to save and email "Unable to save your message to local folders. Possibly out of local file storage space." Please see attached screenshot.

I am not out of storage space.

Any suggestions?

Thank you.

About 6 months ago T-bird stopped sending outgoing messages. Each time I typed even a test message to send to myself, it rejected. Everything else works. I have defaulted to my Comcast email client which is not as friendly as T-bird. T-bird is up to date and none of my settings for outgoing mail was changed. Why won't my mail all of the sudden not process? What do I need to do? Thanks in advance.

Message I get when mail is sent below:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-a2p-647141.sys.comcast.net resomta-a2p-647141.sys.comcast.net ESMTP server not available (396356/151.247.189.217).

My e-mail address is as4625@charter.net My wife's is ann4625@charter.net We have used Thunderbird for several years and all of a sudden it is no longer coming in on our desktops but does come in on my cell phone. HELP PLEASE Andrew Simmons

This is the message I get when I try to send a message. Sending of the message failed. An error occurred while sending mail. The mail server responded: <budguinn@charter.net> sender rejected. Please verify that your email address is correct in your account settings and try again.

I have included a screen shot of my server settings.

I want to configure an automatic response to emails that have been forwarded to me from a particular address. I have created a template for the response and it is saved in the Templates folder. I then attempted to create a Filter Rule to send the response. I believe there should be a Reply with Template option in the Perform these action pull-down, but there isn't. I've attached a screen shot to illustrate this.

I'm using Thunderbird 154.0 and Windows 11. Is there a new way of achieving my objective?

I had to recently change my password on my shaw email account. Now thunderbird won't download my emails. I changed the password in the account settings to match the shaw email account password but I keep getting an error message: "Host contacted, sending login information..." and then after a long delay the error message reads "Login to server pop.shaw.ca with username ... failed". Any idea what I'm doing wrong by simply changing the password? I think this happened before and some wonderful human on this forum told me I had to put something before the password or click/unclick a particular box, but I can't find that old answer to my previous question. Thanks in advance for any help someone can offer!

A few days ago I sent emails and did not see the usual "Saving to Sent (IMAP)". Instead it said something like saving to Sent folder. That's fine, but the emails didn't appear in my Thunderbird Sent folders. I downloaded Thunderbird to see if my version was obsolete. Still no emails in Sent folder. The internet said I could delete my Sent folder, and Thunderbird would re-establish Sent folder. It did not. I can still see my old emails in my Local Thunderbird sent mail, so I deleted about 100 old emails in case the folder was too full. Still, the new emails I was sending did not appear. I checked with a few recipient people and they told me the email go to them. I have tried all the "solutions" I can find. What else can I do to see copies of my outgoing emails.?

I tested out the incoming and outgoing security server and they both are successful at SSL/TLS but I still cannot send email. Is there anything else I should check?

I never had this problem before. People who get my messages, including the copies automatically sent back to me, have ?? ?? instead of the tabs or  ?? spaces I used in the messages. Messages sent to me from other people come in without the ?? marks. Example of my test message copied back to me: ?? ?? ?? ?? ?? ?? 26 Aug 26

To All: Disregard any "?? " in this message; I'm having some trouble with my email program.

How can I fix this problem?

Mail.com (and all its vanity domains like usa.com, europe.com, myself.com, etc.) & many such domains no longer work in Thunderbird. They used to

After your upgrade I was unable to send messages. The incoming I was able to fix but the outgoing I could not fix. I have included the email message sent to me and I have included a picture of the outgoing STMP,

My email works well most of the time. About three or four times a day now I get a message "The current command did not succeed. The mail server for account <account name> responded: System Error (Failure)." Nothing seems obviously wrong that I can see, maybe some of my recipients aren't getting the emails I send? The account in question is at gmail. I've been using it, and Thunderbird, for many years without seeing this error. It seems to have popped up in the last month or two and is now happening a few times a day. I'm running Windows 11 Pro 25H2 build 26200.9168, Thunderbird 153.0.3 Build ID 20260810194242. I have plenty of disk space (1.15TB free) and restarting my system hasn't helped. Is there a way to turn on more logging to get more information about these errors?

You upgraded my program just shortly and now I cannot send email. Everything worked fine before the upgrade but now I can only receive emails. Please help and tell me what to do.
