I can receive emails but cannot send. The error message I get when sending emails. This began as of the most recent Thunderbird update:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <mjndoug22@me.com>... Relaying denied. IP name possibly forged [70.109.132.97]. Please check the message recipient "mjndoug22@me.com" and try again.

I tried to attach/imbed a screenshot of my SMTP server settings but your Browse button below won't allow the paste.

I mistakenly moved a folder into another. It is now a subfolder and I want to move it back. The move command is not working. How do I move a subfolder back to be a primary folder?

Hi. I have approximately 26 folders in gmail and 34 filters that sort messages from my inbox to the appropriate folder on the mail server. I am planning on rearranging the filters and would like to know if there is a preferred way to optimize them. For example, am I better off having individual filters (say from several health providers) that end up saving respective messages into a 'Health' folder OR should I have 1 filter that looks for each provider in turn (OR condition aka 'Match any of...' ) then moves them to the 'Health' folder.

Not worried about performance, but more wondering if one method is more efficient than another.

Also, I seem to recall seeing in the filter help pages that it is preferable to have local storage for filters as opposed to having the mail server sort them out. Why is that?

kind regards, Kirby

I have read the instructions offered in the FAQ's but is not clear to me. when I type in my filter name and then select "+" after the email addy I get error about filter name already exists...

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

I filter messages to move spam to my trash folder. I don't use the spam & junk functions.

I'm on some oddball's list who sends all their spam in bold italics and an uncommon font.

Easy to spot but it's easily 30 a day. I'd love to filter them. I don't see a 'by formatting' option.

Any ideas? Thanks!

Hi, I am trying to login to my emails and after entering my password the following message comes up message comes up. 'Login to server mail.optusnet.com.au with username dianne.hill failed' Can you please help me?

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

using Win 11, Firefox browser, Google search. subfolders are listed but will not open. Using Bing they do open but I prefer Google. If this is a Google problem or a Win 11 can you steer me in the right direction. Thanks My email is artsiii@aol.com

Hello, By default, DoH fails on Max Protection in the latest OS versions listed above. The workaround I've discovered is using https://1.1.1.1/dns-query, but I would rather use the default settings.

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.
