muttrc for gmx.com emails

[Daniel Tameling]

Hi,

I also had this problem when adapting my mutt configuration from gmail to gmx.de.
(I download the mail with mbsync instead of using imap in mutt, but this should still apply)
I had to add this to my configuration:

set copy="yes"
set record="+Gesendet"

You just need to find out, what your sent folder is called and use that in record.

btw: at least the German gmx uses a flat folder structure. So I don't need the [GMX]/ you have in your config.

Did you try

set spoolfile=+INBOX
