I understood that for changing sender's name with mailx I should do the following:
mailx -r [email protected] -s "some subject" [email protected]
But when I do that, I get:
mailx: invalid option -- r
Usage: mail [-iInv] [-s subject] [-c cc-addr] [-b bcc-addr] to-addr ...
[-- sendmail-options ...]
mail [-iInNv] -f [name]
mail [-iInNv] [-u user
Does anyone knows what's happening? thanks,
Answer
The correct syntax is:
mailx -s "some subject" [email protected] -- -r [email protected]
The Usage info shows "[-- sendmail-options ...]" and since "-r" is a sendmail option, you need to use the double dashes first.
