Hi, using KMail on Tumbleweed, I notice some broken encoding when sending a mail to a large number of recipients (yes, sounds strange, but given the fact that there were some hard limits on the number of receipients for some time...) Each line break comes with '=20' at the end of the line. Looking at the mail header: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" -> looks good, but I miss Content-Transfer-Encoding: quoted-printable which probably does the trick (and is in other mails). I assume saving a mail in draft folder of am IMAP account should not change anything. So, the criteria 'number of recipient' (>50 in that case) is the only common denominator. Did anyone else notice this? Thanks Axel
