DKIM signature fail

Hi everyone, When sending a mail on a Microsoft mailbox, the DKIM signature verification fails : dkim=fail (body hash did not verify) I do not have the problem with others webmail like GMail...

Hi. Did you ever get this fixed? Having the same issue, been working with Microsoft support but they aren't getting the issue.

TouLo1190 This error occurs when sending an email encoded in ISO-8859-1 despite having the right headers.

When sending it in UTF-8 I don't have the problem.

I guess Microsoft don't handle ISO encoding correctly.

I hope it will solve your problem.
