mailx - how to change mail from address?

[wallst32]

When I send e-mails using mailx, the "mail from" address is username@hostname.mydomain.com. While this works fine internally, many e-mail servers on the public internet will drop these messages since @hostname.mydomain.com is not a registered domain. How can I change the "mail from" address to username@mydomain.com?

Thanks.

By the way, if there is a command line switch I can use to change it only for specific emails that would be great; or a global setting would work as well.

try:

mailx -r username@mydomain.com recipient@domain.com

cspilman - Great, that works; thanks. I did find the "-r" option searching online, but I think what I had done wrong before was not specify "-r sender recipient" in one continous string.

You can also play with the DM option in /etc/mail/sendmail.cf.

# who I masquerade as (null for no masquerading) (see also $=M)
DM

I used to mess with friends from other companies by changing this. I'd send them email that looked like it was from themselves. Ah, the good old days...
