Original GitHub issue: https://github.com/anonaddy/anonaddy/issues/806

I changed two email addresses in quick succession:

One for Amazon and one for eBay.

Everything was identical, including “Created automatically by catch-all” and all settings.

Since then, I have received six emails within a short period of time: two from Amazon, both without banners, and four from eBay, all with banners.

Are there any known issues with this?

No, there are no known issues.

Did the emails without banners have any spam warning in them?

Do you have any "Rules" set in your account that may have turned the banner off?

No addy.io "Rules" and "Domains". IMO also no spam warnings.

Thunderbird with "Allow HTML Temp" extension and default setting "Plain Text".

I looked at the source code:

Of the 6 emails described:

Amazon sends both emails with “Content-Type: text/plain” and “Content-Type: text/html” and the banner part is exclusively in the HTML section.

Ebay sends two emails with only “Content-Type: text/html” and the banner part is in the html section (logically)
and
Ebay sends two emails with only “Content-Type: text/plain” and the banner part is in the plain section.

So there's not much I / you can do if I mainly want to view the emails in plain format, right?
Except maybe reprogramming the "Allow HTML Temp" extension?

I'm also bit surprised now that Thunderbird displays anything at all with the “Allow HTML Temp” extension and “Plain Text” setting in the two only HTML mails.

I can't see an issue with the Content-Types you've described there, that how it should work with the banner, if there is HTML content then it isn't also included in the plain text version. I'm not familiar with the "Allow HTML Temp" extension but it sounds like that could be causing any issues you are seeing.
