We have a client whose highest priority mx record is misconfigured, it is aspmmx.l.google.com. when it should be aspmx.l.google.com.
We get a 550 error when sending email to them, will the server retry or can we force Zimbra to send to a lower priority MX record ?
No other issues sending to anyone else.
Zimbra 6.0.16 Red Hat 64bit.
