double signature in forwarded mails

[marcscholl]

I have the problem that forwarded mails get my signature appended twice when quote fixing is enabled.

I have multiple signatures in apple mail (one for each of multiple mail accounts), therefore I see a drop-down signature selector in the right above the mail text. When quotefixing for forwards is ON, my signature gets appended in the message pane, however the signature selector says "no signature". When I hit "send", a signature gets appended anyway, so finally, I send a mail with two signatures.

When I hold "alt" on the keyboard while forwarding (so as to temporarily disable quotefixing), the signature is also appended, BUT the signature selection box has the signature selected, so sending does not append another copy.

Any ideas? (BTW: with reply and reply-all everything works just fine)

That's uhm interesting, especially since it only happens with Forwards and not with Reply/Reply-All (I don't think QF handles signatures differently depending on the type).

Do you use other Mail plugins?

[marcscholl]

Yes, I do. I’ve removed them to check: makes no difference. I’ve enabled X.509 signing by default, disabling that is a bit more effort, hence I’ve not yet checked that… —Marc On Mon, Apr 09, 2018 at 15:03h, Robert Klep <[email protected]> wrote (with possible deletions):

What I find strange is 'When I hit "send", a signature gets appended anyway', which sounds like there might be another plugin inserting a signature (if there was, it might be some sort of interaction between that plugin and QF).

QF only removes signatures, and only from messages you received. It doesn't insert signatures itself, nor does it have any code that hooks into the signature-generating part of Mail.

So I'm a bit puzzled at the moment :(

[marcscholl]

Puzzling, indeed. Tried the following: 1. removed QF plugin: everything works as expected. 2. with QF plugin again: second copy of signature is actually added when I hit return after entering the first recipient, not upon „send“. This occurs with only 1 out of 3 accounts. 3. removed signature from Apple mail for the flawed account. Added one again. Same faulty behaviour as before. Would turning on „debuging“ in the QF Advanced pref. pane be of any help? And where would the debug log end up?

Enabling debug logging might provide a clue. The log ends up in the system log, which you can access through the Console application.

All I see in system.log when searching for „quotefix“ is

doesn’t look like big insight. On Mon, Apr 09, 2018 at 15:52h, Robert Klep <[email protected]> wrote (with possible deletions):

It logs more, but not all log lines are prefixed with "QuoteFix".

OK, here is some more:

Thanks.

Sadly, it doesn't really provide any clues (I assume that you also tested with MailFollowUp moved out of ~/Library/Mail/Bundles/).

All I can say is try to disable/enable some options in QF (customized attributions, various Quotefixing settings) to see if there's a magic bullet.

[marcscholl]

Robert, apparently it is to do with the concrete form of the signature. I don’t know what’s causing the trouble, but with a simplified version as included with this mail, the problem is gone. It’s not the „|“s per se, neither the „&“ nor blanks or some such at the beginning of lines, I’m tired of experimenting for today. Should I find out later, I’ll let you know.
