The mblaze message system is a set of Unix utilities to deal with mail kept in Maildir folders. It is a classic command line MUA and has no features for receiving or transferring mail; you are expected to fetch your mail using fdm(1), getmail(1) offlineimap(1), procmail(1), or similar , and send it using dma(8), msmtp(1), sendmail(8), as provided by OpenSMTPD, Postfix, or similar. mblaze expects your mail to reside in Maildir folders.

Its design is roughly inspired by MH, the RAND Message Handling System, but it is a complete implementation from scratch. mblaze operates directly on Maildir folders and doesn’t use its own caches or databases. There is no setup needed for many uses.

mblaze consists of these Unix tools that each do one job:

  • maddr(1) extract addresses from mail
  • magrep(1) find mails matching a pattern
  • mcom(1) compose and send mail
  • mdeliver(1) deliver messages or import mailboxes
  • mdirs(1) find Maildir folders
  • mexport(1) export Maildir folders as mailboxes
  • mflag(1) change flags (marks) of mail
  • mflow(1) reflow format=flowed plain text mails
  • mfwd(1) forward mail
  • mgenmid(1) generate Message-IDs
  • mhdr(1) extract mail headers
  • minc(1) incorporate new mail
  • mless(1) conveniently read mail in less(1)
  • mlist(1) list and filter mail messages
  • mmime(1) create MIME messages
  • mmkdir(1) create new Maildir
  • mpick(1) advanced mail filter
  • mrep(1) reply to mail
  • mscan(1) generate one-line summaries of mail
  • msed(1) manipulate mail headers
  • mseq(1) manipulate mail sequences
  • mshow(1) render mail and extract attachments
  • msort(1) sort mail
  • mthread(1) arrange mail into discussions
