Email notification does not work and the following errors appear in universe.log when this Logging level is enabled (0,IOALM,IOMAIL):
|ERROR|X|IO |pid=p.t| u_recv_msg | recv(socket=107, bytes=3) returns error: Connection reset by peer
|ERROR|X|IO |pid=p.t| u_send_mail | SMTP_MSG_END: Protocol error whith SMTP server SMTP_SERVER on port 25 (-1) (SMTP: 354)
Dollar Universe 6.x and 7.x
Cause type: Configuration
Root Cause: The SMTP Gateway does not support this kind of body type so he rejects the email
Modify the Node Settings of your Dollar Universe node:
SMTP - S_SMTP_MIME_ BODY_TYPE -> delete the content
Save the settings.
Retest the email notification, now it should work.
