Hi Walter,

This is, what I have found:

lrwxrwxrwx 1 root root 14 Feb 11 19:25 /usr/bin/sendmail -> /usr/bin/msmtp

My email address (see above) is different from my userid on my Linux
box and (personally) I dont have configured anything which alias
my userid to my email address or vice versa.

I will now try to let fcron to mail to me (my userid so to speak)
instead of root since the fcrontab is alos mine.

When I do something like this

    cat <file> | mail <my userid>

or

    cat <file> | mail <my userid>@localhost

I get

    send-mail: recipient address <my userid> not accepted by the server
    send-mail: server message: 501 Syntax error in parameters or arguments
    send-mail: could not send mail (account default from /home/<my userid>/.msmtprc)
    Can't send mail: sendmail process failed with error code 65

    send-mail: recipient address <my userid>@localhost not accepted by the server
    send-mail: server message: 550-Requested action not taken: mailbox unavailable
    send-mail: server message: 550 invalid DNS MX or A/AAAA resource record
    send-mail: could not send mail (account default from /home/<my userid>/.msmtprc)
    Can't send mail: sendmail process failed with error code 65


Question for me is: Is "server" my ISP's server? Or a default error
message" or something which is exspected to be installed at my Linux
box?

By the way:
