It was working fine in 52.5.2 I tried delete global-messages-db.sqlite and redownload IMAP folder - still same If I downgrade to Thunderbird 52.5.2 search is working again without problem Data in Thunderbird are journaled email from MS Exchange - I included one of email in attachment for reference I suspecting that problem may be caused by some search fix in TB and mail produced by Exchange. I also tried searching for mail in local folder and same problem, so it is not only IMAP related. Thunderbird 52.6.0 (portable) Windows 7 (czech), IMAP account User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Thunderbird/52.8.0 (steps to reproduce) I include sample email from exchange jurnaling, searching body in this email is not possible after Thunderbird 52.6.0 This is how sample message looks like https://ibb.co/f6Mjky Actual results: What did you do? (steps to reproduce) After update, if I search "body "contains" "X-Spam-Flag: YES" I get no results

I don't quite understand the report. Yes, I actually *fixed* body search in TB 52.6 and TB 52.7: https://www.thunderbird.net/en-US/thunderbird/52.6.0/releasenotes/ https://www.thunderbird.net/en-US/thunderbird/52.7.0/releasenotes/ The sample you supplied only has the single letter "g" in the body: Content-Type: text/plain; charset="UTF-8" g Content-Type: text/html; charset="UTF-8" <div dir="ltr">g</div> X-Spam-Flag: YES/No is clearly *not* in the body of the e-mail but in a header. If you found it before, it was a false positive which we finally fixed. What you want to do is: Right-click on folder, Search Messages, in the search criteria select "Customise" and enter your custom header.

Thank you! Now I finally understand, that my way of searching was bug:) But I'm afraid that there is another problem - I already tried searching by custom header, but it does not work for tags with "-" in it. You can see it on screenshot bellow I can search "TO", or "Received", but not "Authentication-Results" or X-Virus-Scanned https://ibb.co/jdM9tJ Do I do it wrong? Thank you.

(In reply to Sust from comment #2) > Do I do it wrong? Thank you. I don't know. I added a custom header of "X-Bugzilla-Flag-Requestee" and the messages are found. Oh, I just saw: You want to search a header in an attached message, right?

Hello, yes - I want to search in "journaled" message, in attachment. I previously thought that is message body (because I can see content in TB automatically and I could search.) I'm using filters and saved search to categorize messages for quick message trace. So my only option is not to upgrade Thunderbird, until I find way to search in attachment, is that right ? If I look at it retrospectively, the *fix* actually removed feature of searching in attached message in Thunderbird :-) Thanks for your time

Whatever we change, even if we fix a bug, someone complains :-( Strictly speaking, an *attached* message is an *attachment* and should be searchable at all. However, traditionally, these messages are shown inline and so we allow searching their bodies. Now for attached message you want to re-establish searching in the headers of the attached message as if they were part of the body :-( It would make more sense to enhance the search to be able to search attachments, so of a certain type, like images, or by name. I think that's planned for the distant future. Then it would make sense searching headers of attachments as well.

It's something like bug 421187 or bug 439143.

I don't want to complain:) Thanks to you, I finally understand difficulty of my request. Have a nice rest of you day and thanks again for your help!
