PRINCIPLES
|
|
|
|
|
mblaze is a classic command line MUA and has no features related to
|
|
|
|
|
receiving and transferring mail; you are expected to fetch your mail
|
|
|
|
|
using offlineimap(1), fdm(1), procmail(1), getmail(1) or similar and send
|
|
|
|
|
it using sendmail(8), as provided by OpenSMTPD, Postfix, msmtp(1), dma(8)
|
|
|
|
|
or similar. mblaze expects your mail to reside in Maildir folders.
|
|
|
|
|
|
|
|
|
|
mblaze operates directly on Maildir and doesn't use its own caches or
|
|
|
|
|
databases. There is no setup needed for many uses. All tools have been
|
|
|
|
|
written with performance in mind. Enumeration of all mails in a Maildir
|
|
|
|
|
is avoided unless necessary, and then optimized to limit syscalls.
|
|
|
|
|
Parsing mail metadata is optimized to limit I/O requests. Initial
|
|
|
|
|
operations on big Maildir may feel slow, but as soon as they are in the
|
|
|
|
|
file system cache, everything is blazingly fast. The tools are written
|
|
|
|
|
to be memory efficient (i.e. not wasteful), but whole messages are
|
|
|
|
|
assumed to fit into RAM easily (one at a time).
|
|
|
|
|
|
|
|
|
|
mblaze has been written from scratch and tested on a big pile of personal
|
|
|
|
|
mail, but is not actually 100% RFC conforming (which is neither worth it
|
|
|
|
|
nor desirable). There may be issues with very old, nonconforming,
|
|
|
|
|
messages.

personal mail, but is not actually 100% RFC-conforming (which is neither

mblaze is written in portable C, using only POSIX functions (apart from a
|
|
|
|
|
tiny Linux-only optimization), and has no external dependencies. It
|
|
|
|
|
supports MIME and more than 7-bit messages (everything the host iconv(3)
|
|
|
|
|
can decode). It assumes you work in a UTF-8 environment. mblaze works
|
|
|
|
|
well together with other Unix mail tools such as offlineimap(1),
|
|
|
|
|
mairix(1), or mu(1).

|
|
|
|
|
|
|
|
|
|
For example, you could decide you want to look at all unseen mail in your
|
|
|
|
|
INBOX, oldest first.
|
|
|
|
|
mlist -s ~/Maildir/INBOX | msort -d | mscan
|
|
|
|
|
To operate on a set of mails in multiple steps, you can save a list of
|
|
|
|
|
mail as a sequence. E.g. add a call to ‘mseq -S’ to the above command:
|
|
|
|
|
|

|
|
mlist -s ~/Maildir/INBOX | msort -d | mseq -S | mscan
|
|
|
|
|
|
|
|
|
|
Now mscan will show message numbers and you could look at the first five
|
|
|
|
|
mails at once, for example:
|
|
|
|
|
mshow 1:5
|
|
|
|
|
Likewise, you could decide to look at all freshly received mail in all
|
|
|
|
|
folders, thread it and look at it interactively:
|
|
|
|
|
|
|
|
|
|
Likewise, you could decide to incorporate (by moving from new to cur) all
|
|
|
|
|
new mail in all folders, thread it and look at it interactively:
|
|
|
|
|
mdirs ~/Maildir | xargs minc | mthread | mless
|
|
|
|
|
Or you could look at the attachments of the 20 largest mails in your
|
|
|
|
|
INBOX:
|
|
|
|
|
mlist ~/Maildir/INBOX | msort -s | tail -20 | mshow -t
|
|
|
|
|
|
|
|
|
|
Or you could list the attachments of the 20 largest mails in your INBOX:
|
|
|
|
|
mlist ~/Maildir/INBOX | msort -S | tail -20 | mshow -t
|
|
|
|
|
|
|
|
|
|
Or apply the patches from the current mail:
|
|
|
|
|
mshow -O. '*.diff' | patch
|
|
|
|
|
|
|
|
|
|
As usual with pipes, the sky is the limit.
