How does mutt command pick senders Details

Hi All,

We use mutt in one of our scripts to send files as a part of a batch job . The command works nicely but i want to know from where does mutt pick the sender details. As the sender id is different if i use mutt and Mail utility. I can not change the command to mail as it is a part of the package but i have to change the sender details .


mutt -a checkCol.sh -s "test" amit1_x@abc.com < checkCol.sh

The mutt manual page has an extensive section on how to customize your .muttrc
