My guess is that mutt looks at the locale environment (LANG and LC_*) to set the encoding of the source data, and tries to recode it into one of the encodings in send_charset. If you _know_ your data is iso-8859-1 but your LANG etc. is something else, try changing LANG locally in your driver script/program. BTW, running mutt non-interactively has always seemed strange to me. Why not use something simpler like mailx, or even /usr/sbin/sendmail? -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
