Contact form, SPAM email mod.: Odd line breaks

[Huhu]

I am encountering strange line breaks in emails from the Contact Form and in the modeation email form teh Spam protector; even links are broken this way.
See here, the "="

Code: Select all

Can those line breaks be deactivated within s9y?

Does the mails header source code contain "Content-Transfer-Encoding: base64"?
If this is true, your PHP is missing the "imap_8bit" function. Ask your ISP to compile that with PHP.

[Huhu]

No, sorry, it says "Content-Transfer-Encoding: quoted-printable"

Hmm ok, then this looks like that a linebreak =0A is not properly converted back, while it remains to show a leftover = sign. Is it "=0A" in the mails source code? Is there also a "Content-Type: text/plain; charset=UTF-8"? Does every comment mail arrive like that, or just some?

Maybe this unproper view isn't the fault of the sender, than of your receiving email client, else I don't really have an idea why this should happen like this, and I even wonder why it breaks < 75 char lines too.

Hej,

thanks for helping!

Ok, here the source code:

Code: Select all

X-Mailer: Serendipity/1.6.2
X-Engine: PHP/5.2.17
MIME-Version: 1.0
Precedence: bulk
Content-Type: text/plain; charset=UTF-8
Auto-Submitted: auto-generated
Content-Transfer-Encoding: quoted-printable

En ny kommentar har skrivits (...) till artikeln =
med namnet "Kontakta".=0A=0AAnv=C3=A4ndare IP-adress: X.XX.XX=
X.XX=0A=0AField  'Namn': XXXX=C3=B6m=0AField  'E-post': XXXX=
X@XXail.com=0AField  'Har du ett eget lag?': Nej=
=0A'Me=
ssage': ...

So does it read:

Code: Select all

En ny kommentar har skrivits (...), till artikeln =

Användare IP-adress: X.XX.XX=
X.XX

Field  'Har du ett eget lag?': Nej=

No, the normal =0A linebreaks by posted comment forms are read well.

It must be somehow the imap_8bit "breakage" ..., which breaks with = in the source code and the email client "should?" stick that together again (at least my Thunderbird is doing this well). In example

Code: Select all

Im Blog John Doe' area51 wurde ein neuer Kommentar zu Eintrag "Kontaktformul=

 Doe=0A ... etc.

Thanks! Interesting. I am using Mail.app with OS 10.6, and this error only occurs with s9y so far.
Any other user of mac mail out there who has the same problem?

This seems to be Mail.app related, see
