Does anyone know how to avoid this, eg using alternactive smtp addresses?
That IP is tied to a relay, or outbound mail server, in our system. Many IPs can tie back to secure.emailsrvr.com, and this is dictated by our load balancer. We are aware of the blacklist and are awaiting it's removal.
In the meantime as a work around you can ask if the recipient can safelist the sender, sender's domain, or that IP. What would also be helpful is if you create tickets with the bouncebacks so that we can add the ticket as an affected user on our internal tracking system.
