Mine that I use to test openssl s_client -connect massmail.uconn.edu:465
openssl s_client -starttls smtp -connect massmail.uconn.edu:587 telnet is just for port 25 YMMV. -ANGELO FAZZINA UITS Service Manager: Spam and Virus Prevention Mass Mailing G Suite/Gmail ang...@uconn.edu University of Connecticut, UITS, SSG, Server Systems 860-486-9075 -----Original Message----- From: owner-postfix-us...@postfix.org [mailto:owner-postfix-us...@postfix.org] On Behalf Of James Reynolds Sent: Thursday, November 30, 2017 4:21 PM To: Postfix users <postfix-users@postfix.org> Subject: Re: smtpd_sasl_auth_enable is true but sasl support is not compiled in (postfix-gento) I have never heard of using openssl s_client instead of telnet so I tried to figure out how to use it. I could connect to my server with the following. openssl s_client -connect 10.0.1.1:25 -starttls smtp And I can do "HELO" and "MAIL FROM:" but when I try to enter "RCPT TO:" I just get this output and I can't go further.
