Probably the worlds smallest, simplest, yet full featured eMail client without any dependencies beyond a working GNU environment running Bash.
Use it as a fallback, as a quick & slim alternative or as a tool to read, send and manage messages.
Following commands are available:
p(eek) peek for new messages
s(tatus) request mailbox status
n(ew) list new messages only
t(ail) [N] list the latest N messages
l(ist) [N[-N]]... list messages
r(ead) [N[-N]]... read message
x(tract) N[-N]... extract attachments of message N
f(ile) N[-N]... file message
d(elete) N[-N]... remove message
a(nswer) N answer message
w(rite) ADDRESS write a message to ADDRESS
m(ime) FILE show a message file in MIME format (e.g. *.mbs)
c(lear) clear screen (or CTRL+L)
h(elp) show this info
q(uit) quit (or CTRL+D)
You may invoke the commands directly from the command line, e.g.:
$ readmail s 'f 1' 'r 3-5' q
Or inside the interactive shell.
Just run readmail or create a ".readmailrc" in your home directory and put the following lines into it (fill in the values in brackets):
POP_HOST='(your POP3 server)'
POP_ACCOUNT='(your POP3 account)'
POP_PASSWORD='(your POP3 password, this is optional)'
Append this block to configure your SMTP settings:
SMTP_HOST='(your SMTP server)'
SMTP_ACCOUNT='(your SMTP account)'
SMTP_PASSWORD='(your SMTP password, this is optional)'
If you don't want to give passwords, readmail will ask you for it.
Quickly get the size of your mailbox:
$ readmail s q
Show your latest message:
$ readmail r q
Get the number of new messages since the last call:
$ FORMAT="%d\n" readmail p q
Send a message in one line:
$ ATTACHMENTS=' ' SUBJECT='subject' BODY='body' \
readmail 'w john@example.com doe@example.com' q
Send one or more files:
$ ATTACHMENTS='file1 file2' SUBJECT='subject' BODY='body' \
readmail 'w john@example.com' q
