Hello Exim Sages, I've been running Exim for a close to two years now without many issues; but I've had this persistent inability to configure Exim to work with authenticate on send in conjunction with some of the Microsoft MUAs.
Now i know these MUAs are often not compliant etc but I am also aware it's possible to massage Exim into working with them. I've tried several times but I'm now reaching out for help. I'm currently running Exim 4.72. In my Exim configuration file I have daemon_smtp_port = smtp : smtps : submission # 25, 465, 587 tls_on_connect_ports = 465 Now in my log file it tells me Exim has started with STMP on ports 25, and 587 and SMTPS on port 465. So that looks correct for working with Microsoft MUA's but when I try to connect using 465 and SSL using Windows Live Mail for example, I get the error message in my log file: "SMTP protocol synchronization error (input sent without waiting for greeting):" If understand correctly this is characteristic of tls on connect problems ? Furthermore; to confuse me further; when I start exim using -tls-on-connect at the command line - it works with my Microsoft MUA without issue. I though perhaps it was connecting to another port that 465 but I saw no evidence of this, in fact both other ports (25, 587) are firewalled from client. Does -tls-on-connect do something slightly different from the config directive tls_on_connect_ports apart from allowing you to select specific ports?
