[Voyage-linux] Tiny SMTP server( daemon)

[Christoph Fritsche]

Hi Ba,

those guys over at OpenWRT tend to use xmail. Xmail looks like a fully 
featured SMTP Server including SSL suport.

http://packages.debian.org/lenny/xmail

If mails are only generated locally (using mutt, mail, ...) you might 
want to give:
http://packages.debian.org/lenny/msmtp
http://packages.debian.org/squeeze/dma
a try.

qmail is only available as source in the non-free repository, building 
from source is no fun at all within an embedded environment.  Unless you 
have a development station for cross compiling around you should skip 
this option.

Except the disk space the binaries, libs and config files might use up, 
you should more worry about the mail queue. Everything is put into a 
queue (on the disk) in the first place. You should try to keep this off 
the flash. Heavy write access will burn out your flash sooner or later. 
Think of using tmpfs, aufs, unionfs... and store the message queue in 
RAM. RAM is cheap by the way.  In case of a power failure or other means 
of sudden death the mails kept in RAM are lost, you might want to rsync 
them on disk regularly (hourly) in order to keep messages which are 
currently not deliverable (remote STMP server down).

Cheers,
Christoph
