So it seems; because outgoing ipv4 port 25 is now blocked by the hosting company that courier-mta managed to at least squeak through an ipv6 connection to the other end that happens to accept ipv6. Cool, but I have no idea how, or time, to set up ipv6 and most destinations won't accept ipv6 anyway. I have to set up a smarthost route to either one of my other courier based mailservers or mailgun/sendgrid but I've never had to stoop so low before. I have used ssmtp on a few really small VPSs and I guess that is an option for me in this case just but I am unsure how to integrate incoming port 25 using esmtpd with outgoing via ssmtp. In looking at esmtproutes I can't see how I can authenticate to port 587/TLS or 465/SSL on the other end so how do I use esmtproutes... domain:relay[,port][/SECURITY=STARTTLS][/SECURITY=REQUIRED][/SECURITY=SMTPS] to emulate something like this setting for ssmtp? mailhub=smtp.sendgrid.net:587 AuthUser=sendgridusername AuthPass=sendgridpassword UseSTARTTLS=YES ------------------------------------------------------------------------------ Transform Data into Opportunity.
