In this post I’ll explain how to configure a Nortel/Avaya 4550T-PWR for a real application: SOHO with pc and Voip PBX using snom ip phone.
To begin I’ll explain how to reset the switch, upgrade firmware: at the end I’ll show the configuration step involved to create 2 separated VLAN (data e phone). Continue reading
Check if sendmail is compiled with TLS (for encryption) and SASL (for authentication). This is the command to use to check it.
#/usr/sbin/sendmail -d0.1 -bv root
You must read something like “Compiled with…STARTTLS”
Att.: If you’ve installed sendmail using yum, TLS support is present !
Install all these packages
# yum install sendmail sendmail-cf cyrus-sasl-plain cyrus-sasl-md5
# cd /etc/pki/tls/certs
# make sendmail.pem
