Mails blocked because of too many white spaces (webapp 3.4.22.XXX and 3.4.23.XXX)
-
Hello,
we have some trouble with sending html mails.
Kopano Deskapp & Webapp, Outlook and Thunderbird show the content correct, but they are sometimes blocked by other mailservers with an error which says the mail is corrupt.
After some logging they said, the mail contains to many linebreaks and white spaces.
This problem occurs as far as i know only when answering mail which original were sent by Outlook.
Maybe the problem is that outlook uses charset “iso-8859-1” and kopano uses “utf-8”.best regards
