Squirrelmail runs on the same machine as postfix and sends mail fine when postfix is configured for smtps 465. I read smtps is deprecated so I switched postfix to submission 587 and changed the port in squirrelmail's config but squirrelmail will no longer send mail. Thunderbird sends mail fine over port 465 or 587. In squirrelmail I get: ERROR: Message not sent. Server replied: 0 Can't open SMTP stream. In the postfix log I get: [postfix/smtpd] connect from localhost[127.0.0.1] [postfix/smtpd] lost connection after UNKNOWN from localhost[127.0.0.1] [postfix/smtpd] disconnect from localhost[127.0.0.1] Does anyone know how to fix this? - Grant ------------------------------------------------------------------------------ Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of discussion for anyone considering optimizing the pricing and packaging model of a cloud services business.
