Broken line in moderation and authentication mailto links

[bmarchal54]

Version

6.2.72

Installation method

rpm

Expected behavior

When sending a message to an authenticated or moderated list, the mailto link is written on a single line in the email client.

Actual behavior

the mailto link is broken about half the time.
This means that the key is found on the line below and not at the end.
If we look at the source code of the message, when it is correct, we find an '=' sign at the end of the mailto line and the rest of the key in the line immediately below. When there is a problem, the whole key is under the bottom line.

I upgraded to version 6.2.72 last week on a Rocky 8 OS.
The other features of Sympa seem fine to me.

Steps to reproduce

I send several messages in a row to an authenticated list, but it's the same for a moderated list. Some messages sent by Sympa are correctly composed, others are not.

Additional information

In a correct message, here is the piece of code corresponding to the message sent

------------=_<[email protected]>
Content-Disposition: inline
Content-Type: TEXT/PLAIN; charset="UTF-8"
Content-Transfer-Encoding: QUOTED-PRINTABLE
MIME-Version: 1.0
Content-length: 291
