How are the files sent in the email?

If I run 'file' on your two files, I see that correct.rem has <CRLF>
line terminators and wrong.rem has only <LF> terminators. If I attach
the two files to an email and send it to myself, it makes no difference
whether the mail passes through MailScanner or not. What determines the
line terminators on the attachments saved from the email is the MUA that
I use to save them. If I use Thunderbird on Windows, both files are
saved with <CRLF> and if I use mutt on Unix, both files are saved with
<LF>. In other words, they are text files and they are saved in the
normal format for text files on the platform. For transfer between MTAs
via SMTP, they are always transferred with <CRLF> line terminators per
the SMTP standard. If you want to preserve the line endings, the file
has to be sent encoded and with some content type other than text, e.g.
