Well I know almost nothing about gmx's SMTP server, other than the requisite knowledge to send mail through it from a MUA, which I can do from icedove and mutt (but not mutt here, currently. Can with mutt on my remote server). My remote server (myownsite.me, from which I am sending this mail) has postfix and dovecot, but clearly, the problem is on my local machine (and affecting mutt, but not icedove). > > If you have not customized it then you are using /usr/sbin/sendmail > and the message is handed off to your system MTA for delivery.

If I run that as a regular user, I just get exim: permission denied. If I run it as root, no message appears.
