Tobias Rundstrom supplied a patch to ssmtp to enable secure mailtransfer
|
|
between your local (ssmtp) machine and the mailhub. It also supports
|
|
authentication with RSA keys, to enable you to (if you patch the MTA on
|
|
the mailhub) have RSA key checks on all relay mails.
|
|
|
|
He wanted this so that he could have the same SMTP server on his laptop even
|
|
when he moved around on different networks. As he said - "I could have used
|
|
postfix as I did on my mailhub, but that was overkill, so I patched the
|
|
smallest program there was :)"
|
|
|
|
information about smtp over ssl for postfix is avalible at:
|
|
http://www.aet.tu-cottbus.de/personen/jaenicke/pfixtls
|
|
|
|
How to use this:
|
|
I had to add the following config directives:
|
|
|
|
UseTLS=YES/NO
|
|
Set this to yes and ssmtp will try to connect with SSL to the remote machine.
|
|
|
|
UseSTARTTLS=YES/NO
|
|
Do a EHLO/STARTTLS before starting the SSL negotiation (see http://www.ietf.org/rfc/rfc2487.txt).
|
|
|
|
UseTLSCert=YES/NO
|
|
Set this to yes to make ssmtp identify itself with a certificate.
|
|
|
|
TLSCert=<file>
|
|
Specify which certificate file should be used.
|
|
|
|
|

TODO:
|
|
* Check server certificate for changes and notify about it.
|
|
* Diffrent Certificate and Key file?
