Hello,
ssmtp is a simple replacement for /usr/sbin/sendmail that takes the
mail piped into it and _immediately_ forwards it to a mailhub, and
cannot receive mails by smtp.
| It accepts a mail stream on standard input with recipients
| specified on the command line and synchronously forwards the
| message to the mail transfer agent of a mailhub for the mailhub
| MTA to process. Failed messages are placed in dead.letter in the
| sender's home directory.
This makes it a real bad choice for dial-up users because they are not
connected all the time and like to answer the 5 mails they just
received by fetchmail and compose another two, place these in the
local queue and send all seven mails at once, when they dial in later,
instead of dialing in 7 times.
ssmtp is the right thing for the workstaions in a LAN which
have permanent connection to the LAN's mailhub.
OTOH masqmail seems to be perfect for dial-up-users, but _afaics_ it
is not (yet) ready for joe user, because something like
/usr/sbin/eximconfig is missing. Additionally README says:
| but it is NOT supposed to be installed in a network with a
| permanent internet connection (at least if it is not behind a
| secure firewall) because it has no ability to check for undesired
| relaying or spam filtering.
but 'listen_addresses="localhost:25"' in the _default_ configuration
file (wishlist bug-report follows) and/or libwrap-support should take
care of this problem.
