mutt: Bad IDN

[Dirk Rosenblatt]

On my old 11.11 Server I use Mutt 1.5.18 and it works fine. Now we have to move to a new one (IA64/11.31). I downloaded the actual version 1.5.21 from http://hpux.connect.org.uk/hppd/hpux/Networking/Mail/mutt-1.5.21/ and copied the config.

When I try to send a mail I get the error:
Bad IDN in "from": 'xxx.de'

Find very few infos in the internet...

mutt -D | grep -i char

ascii_chars is unset
assumed_charset=""
attach_charset=""
charset="iso-8859-1"
config_charset=""
send_charset="us-ascii:iso-8859-1:utf-8"
status_chars="-*%A"
to_chars=" +TCFL"

Is this correct?
How can I change the settings (I think, we do not have a config-file)?

Most people solved the problem by downgrading. But I did not find a link for version 1.5.18 (or whatever works)

Hi

I could solve the problem with simple one configuration entry in /usr/local/etc/Muttrc in my hp-ux 11..31  IA64 machine

iconv-hook UTF-8 utf8

*****except this nothing was changed
