Hallo everyone,
I can't get rid of the authentication failure on testing SASL libreries.
I have a configuration like: Postfix+Amavis-new+Clamav+sasl+cyrus-Imap. For
virtual alias map (and mailobox and domains ) i have a mysql database.
Before the installation of sasl libraries all the various test ran fine.
After that, I can already send and receive email with the requested
rewriting of address but I obtain a TLS error because the
/etc/pki/tls/private/localhost.key and /etc/pki/tls/certs/localhost.crt does
not exist. I think that this loss influence the authentication process ( and
should be the cause of the authentication failure) but I don't know how and
why this files doesn't exist however the configuartions seams right.
I ran the saslfinger that showed me the configuration end all seams right.
mybe did I install a corrupted packge or there is something that I must do
that I don'know)??

Excuse me if this seams banal but I'm little got stuck
PS: I'm testing the authentigation doing a smtp session ( via telnet)

thanks
Alessia
