Hi, got this error in exim mailog, when an external web app send authenticated via exim, and the sender domain have smtp relay unathenticate enabled (external proxy), I got

R=send_via_unauthenticated_smtp_relay T=remote_smtp: message has lines too long for transport

I think exim does not try to send out the email

someone does have any ideas?

Setup an SMTP relay first

you mean this? user/pass not needed (already working with other hestiacp installation)

ok after debugging little bit, tried without remote relay and does not change

R=dnslookup T=remote_smtp: message has lines too long for transport

testing different sending email, can be a body size problem, maybe too big
