[[email protected] ~]# mutt -f /var/spool/mail/john
You may also use “-R” option to open a mailbox in read-only mode.

In this example, following command will send a test Email to [email protected]. The “-s” option is used to specify Subject of the mail.
[[email protected] ~]# mutt -s "Test Email" [email protected]
When you enter the above command in the terminal, it opens up with an interface and confirms the recipient address and subject of the mail and opens up the interface, here you can make changes to recipient mail address.
- Change recipient email address pressing t.
- Change Cc address with c.
- Attach files as attachments with a.
- Quit from the interface with q.
- Send that email by pressing y.
Note: When you press “y” it shows the status below that mutt is sending mail.
Add Carbon copy(Cc) and Blind Carbon copy(Bcc)
We can add Cc and Bcc with mutt command to our email with “-c” and “-b” option.
[[email protected] ~]# mutt -s "Subject of mail" -c <email add for CC> -b <email-add for BCC> mail address of recipient
[[email protected] ~]# mutt -s “Test Email” -c [email protected] -b [email protected] [email protected]
Send Emails with Attachments
We can send email from command line with attachments by using “-a” option with mutt command.
[[email protected] ~]# mutt -s "Subject of Mail" -a <path of attachment file> -c <email address of CC> mail address of recipient
[[email protected] ~]# mutt -s "Site Backup" -a /backups/backup.tar -c [email protected] [email protected]
Here in above snapshot, you can see that it shows attachment attached with the mail.
Use of muttrc file
If we want to change the senders name and email, then we need to Create a file in that particular user’s home directory.
[[email protected] ~]# cat .muttrc
Add the following lines to it. Save and close it.
set from = "[email protected]" set realname = "Realname of the user"
To print the help menu of “mutt”, we need to specify “-h” option with it.
[[email protected] ~]# mutt -h Mutt 18.104.22.168i (2006-07-14) usage: mutt [ -nRyzZ ] [ -e <cmd> ] [ -F <file> ] [ -m <type> ] [ -f <file> ] mutt [ -nx ] [ -e <cmd> ] [ -a <file> ] [ -F <file> ] [ -H <file> ] mutt [ -i <file> ] [ -s <subj> ] [ -b <addr> ] [ -c <addr> ] <addr> [ ... ] mutt [ -n ] [ -e <cmd> ] [ -F <file> ] -p -v[v] options: -a <file> attach a file to the message -b <address> specify a blind carbon-copy (BCC) address -c <address> specify a carbon-copy (CC) address -e <command> specify a command to be executed after initialization -f <file> specify which mailbox to read -F <file> specify an alternate muttrc file -H <file> specify a draft file to read header from -i <file> specify a file which Mutt should include in the reply -m <type> specify a default mailbox type -n causes Mutt not to read the system Muttrc -p recall a postponed message -R mailbox in read-only mode -s <subj> specify a subject (must be in quotes if it has spaces) -v show version and compile-time definitions -x simulate the mailx send mode -y select a mailbox specified in your `mailboxes' list -z exit immediately if there are no messages in the mailbox -Z open the first folder with new message, exit immediately if none -h this help message
