I have some more details on the issue.
I use the Form Tools 2.2.5 with the standard php mail function, no module.
I have some "normal" forms. For sending the form as e-mail I have defined a HTML template and a text template as well.
While using PHP 5.3, it works well, and mails are sent.
If I switch to PHP 5.5 or 5.6, the user doesn't see a difference, but the mails won't be sent. Also the test mail shows an sending error, if I choose HTML & Text as mail format. If I choose HTML only or text only, the test mail will be sent.
If I delete the text template, mails are sent also with PHP 5.5/5.6.
It seems, that there's an issue with multipart mails in PHP 5.5+.
