OPS345 Lab 7

• dovecot with imaps
• webmail

• dovecot installed in previous lab
• use the same keys generated in www lab:
• scp -P 2212 -i keys/ssh/ops345-all-aws-machines.pem keys/asmith15.ops345.ca.* andrew@34.202.103.43:~
• [root@email andrew]# cp asmith15.ops345.ca.cert.pem /etc/pki/tls/certs/
• [root@email andrew]# cp asmith15.ops345.ca.key.pem /etc/pki/tls/private/
• configure postfix to enable encrypted connections from client software. add this to the bottom of main.cf:

# Settings to enable secure SMTP via STARTTLS using my key and certificate:
smtpd_tls_auth_only = no
smtpd_use_tls = yes
smtp_use_tls = yes
smtpd_tls_key_file = /etc/ssl/private/vm2.andrewsmith.ops.key
smtpd_tls_cert_file = /etc/ssl/certs/vm2.andrewsmith.ops.crt
smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem
tls_random_source = dev:/dev/urandom
smtpd_tls_loglevel = 1

• test with telnet/EHLO: should say 250-STARTTLS
