Description Erik Quaeghebeur 2020-08-11 12:30:04 UTC

KMail gave a warning when a URL in a plain text email contained a port number. It said that

“This email contains a link which reads as 'https://example.com:443/blablabla' in the text, but actually points to 'https://example.com/blablabla'. This is often the case in scam emails to mislead the recipient”

KMail should be a bit smarter here. I actually also think that this kind of warning message is not appropriate for plain text emails in any circumstance. (Other types of URL warnings may be.)

N.B.: Missing period at end of warning.

Do you have a test case so I can create autotest against it please ?

I'm still on 20.04.3. I haven't tried 20.08.0 yet. If you don't see it in that version, feel free to close mentioning the exact version for which it was working correctly for you. Once I update to that or beyond, I can check again and reopen if it persists for me.
