Hi, I've been studying the possibility of using relayd to implement a redundant SMTP server for the end-user machines in my lab (ie a server whose clients will be MUAs, possibly remote ones needing authentification, rather than MTAs) . However, it seems to me that relayd lacks some features to achieve my goals:
* provide unencrypted connections on ports 25 and 587 - no problem * provide SMTPS (port 465) crypted connections without client certificated - no problem * provide SMTP AUTH support for encrypted transports for clients with no certificates - this should work over SMTPS; see below for STARTTLS. * provide SMTPS (port 465) crypted connection with a client certificate is used for authentification - how can the proper from the certificate passed to sendmail(8)? * provide STARTTLS support for connections on ports 25 and 587 - probably not supported by relayd, unless a specific smtp+starttls protocol handler is implemented. And again, need a way to pass client certificate information to sendmail(8). Any hints or tricks to solve the issues are welcome. I would love to be wrong when I say that currently relayd can't provde all of the above. Thanks. -- Matthieu Herrb
