Following this I get:
sendmail: recipients with -t option not supported
Thanks for the feedback. We're reworking this document internally.
We're still having the same issue. Is this resolved already?
@viewbook I worked around this by using SMTP directly from rails.
We did too without success on port 25 for smpt.sendgrid.net, what SMTP port did you use?
Thanks, sendgrid documents port 465, http://support.sendgrid.com/entries/131119-help-smtp-port-25-is-being-blocked
Port 587 did work with sendgrid. http://docs.sendgrid.com/documentation/get-started/smtp-ports/
@viewbook "Port 465 shows up Appendix A of the 1996 non-standard standard The SSL Protocol Version 3.0 as “Simple Mail Transfer Protocol with SSL”. Unfortunately, it’s not registered for SMTPs, it’s registered for URD – “URL Rendesvous Directory for SSM” by Cisco. The recommended approach, at least for authentication, is to use START TLS encryption on submission port 587."
