attachment.pcx zypper mails

Dear fellows,

as asked in the “programming/cron jobs” forum (failed cron jobs send “attachment.pcx”? - openSUSE Forums): apparently, postfix treats mail bodies containing non-printable characters as a PCX attachment…

Is that normal? Where can I configure whether my MTA turns such not-entirely-plain mail bodies into attachments, instead of sending it as-is?

Thanks in advance for all ideas!

As per the Simple Mail Transfer Protocol (SMTP), you can not send non-printable characters in the mail body without defining further mail-parts as attachment etc. If Postfix just send it as part of the mail content, such mails will be rejected by almost all of the servers and receivers as non-compliant.
