How to set the From email address for mailx command?

You can use the "-r" option to set the sender address:

mailx -r me@example.com -s ...

shell email solaris ksh mailx

The "-r" option is invalid on my systems. I had to use a different syntax for the "From" field.

-a "From: Foo Bar <foo.bar@someplace.com>"

shell email solaris ksh mailx

In case you also want to include your real name in the from-field, you can use the following format

mailx -r "me@example.com (My Name)" -s "My Subject" ...

If you happen to have non-ASCII characters in you name, like My AEÆoeøaaå(Æ= C3 86, ø= C3 B8, å= C3 A5), you have to encode them like this:

mailx -r "me@example.com (My =?utf-8?Q?AE=C3=86oe=C3=B8aa=C3=A5?=)" -s "My Subject" ...

Hope this can save someone an hour of hard work/research!
