Can mutt send mail from command line without command line parameters, with subject, cc, bcc, reply-to, in-reply-to all defined inside mail.txt file with body of the message too (the same file format like mutt opens to me when i press m-send mail, or r-reply to mail).

... So that I can:

  • press 'r' on received mail, prepare my reply message, save it with ':w ~/preparedmail.txt' in vim ... cancel sending
  • and than run $ at 8:00 <<< "mutt < ~/preparedmail.txt"

... or is there other tool that will accept this file format. Or other way to achieve this.

    if you can run at 8:00 am <<< mutt , what's the problem with using command-line options, e.g. running at 8:00 am <<< cat ~/preparedmail.txt | mail -s subject recipient@example.com ?

  • @cas it is grate when i want to send new message. But when i want to REPLY there are special headers that i want to invoke, like in-reply-to: hexNumbersLine ...and mutt itself prepare all that well in interactive use with 'r' shortcut, it also prepares 'include original message' and stuff.

  • yes. you can write the msg in mutt, and save it to a file. you can use any mail program (mail, sendmail, a perl script, etc) to send it.

  • @cas hm, sorry, so you actually meant 'mail' not 'mutt' inside your first comment. ok i will just find out what is most easy to configure for imap.

If you are using sendmail or postfix to deliver the mail, you can use

sendmail -t <~/preparedmail.tx

and it will extract the destination recipient(s) from any To: Cc: or Bcc: header lines in the file (upto the first blank line) and send the file as mail.

For people having configured a tool like mutt to send mail directly, an easy solution is to use msmtp, a program to send a prebuilt mail which also takes -t like sendmail to get the recipients, and is much easier to configure for smtp with credentials than postfix or sendmail. Here is an example ~/.msmtprc to send mail to gmail:

account gmail
 host smtp.gmail.com
 port 587
 tls on
 # from myname@gmail.com
 auto_from on
 auth on
 user myname@gmail.com
 # password mypassword
 passwordeval gpg -d ~/.msmtp.password.gpg

account default : gmail

Don't forget to chmod og= ~/.msmtprc.

  • nice, but configuring sendmail (which is also mail-server as i understand) for imap, than credentials... seems little complicated

  • I agree. you could also look at msmtp, a program to send a prebuilt mail which takes -t like sendmail, and is much easier to configure for smtp with credentials than postfix or sendmail.

  • i am marking your answer as correct, because of now mentioning MSMTP too. For my situation (using external smtps's not own mail-server), msmtp is the BEST tool... maybe you should add that info inside 'for us without sendmail/postfix/exim ambitions', for external smtps like mutt+gmail users.
