/usr/bin/sendmail vs /bin/mail from field

new2ss · #1 (**permalink**) 07-09-2009

Hi all, I am logged into my linux machine as user bobby. My machine's hostname is myserver.domain.com

when i execute this command

Code:

echo "testing" | /usr/sbin/sendmail -f bobbyA@coldmail.com friend1@somemail.com

friend1@somemail.com receive the email from sender bobbyA@coldmail.com

when i execute this command

Code:

echo "testing" | /bin/mail -s "haha" "From:<bobbyA@coldmail.com>" 
friend1@somemail.com

friend1@somemail.com receive the email from sender bobby@myserver.domain.com. What should I do to make the second case reflect bobby@coldmail.com as the sender?Is there any flag i can set for mail command to send the mail out as what i specify on the command as the sender rather than the user@host executing the command?

Some implementations of mail allow you to pass in sendmail options after the "to" address. So you can do:

Code:

echo "testing" | /bin/mail -s "haha" friend1@somemail.com -- -f bobbyA@coldmail.com

This actually worked on my system.

Hi otheus,

your command worked for me too. Thank you very much.
