Do you also have empty subject and sender fields?

Do you have blank headers (subject, from, date) with each email? When you say it is showing as code do you mean the body of the message rather than the headers or are the headers intact as normal?

some headers are filled some are blank, all bodies of email are code

heres a part of your email...this shows the header...others are blanl

could bitdefender be doing this?

I also run Bitdefender, but tried with protection disabled. It did'nt change anything. Problem started today 08/11/25

@illisible so you are having same problem as me?

Are any of you using Bell sympatico.ca as a provider?

illisible,

In my case, the problem began precisely at 12:05 PM MDT and continues to now, 4:24 PM MDT.

Here is the body of a message that I just sent to myself.

I have also attached a screen capture of the outgoing eMail message.

Same problem here, also started today  :((((

As information, I run two Win 10 Pro PCs with Bitdefender Total Security. Mozilla T-bird packages on both machines are encountering this problem in the last day or so. I have disabled Bidfender too, to no avail. Interestingly, email sent from a local newspaper is received normally (body and subject heading in tact), but by and large email sent from Mozilla T-bird, Yahoo webmail, and MS Outlook arrive full of code without subject headings.

thanks everyone for the help!

so do we report this somewhere or what? :)

so do we report this somewhere or what? :)

Don't know where. As I mentioned on similar threads, this issue seems to concern pop servers, not imap. If that help to debug.

I found this possible remedy in the T-bird forums (https://support.mozilla.org/en-US/questions/1479331). The second item from "reddit" worked for me. I did not try the exclusions suggestion:

Add the TB profile folder as an exclusion in BD settings, as BD is a likely reason for the problem (it's bypassed in Windows safe mode).

https://www.bitdefender.com/business/support/en/77209-342987-exclusions.html

You might also have to disable scanning of secure (SSL) connections:

https://www.reddit.com/r/BitDefender/comments/jnlmf7/how_to_disable_ssl_inspection_in_bitdefender/

I am computer stupid (somewhat) my late husband was the one that kept things up and running

Found the place to report. Will let you know if they respond

mozilla says they'll try to respond in 2 business days
