Hi!

I configured my mailbox to reject mails that are delivered via unencrypted SMTP connections and I think also TLS encrypted SMTP connections with weak ciphers.
Since then only some newsletter mails were delivered to my inbox, all others were rejected.

I think the root of the problem is that some servers at createsend are misconfigured.

From what I can tell by now, these servers use TLS encrypted connections with strong ciphers:

  • mx65.b.outbound.createsend.com
  • mx200.a.outbound.createsend.com
  • mx201.a.outbound.createsend.com
  • mx202.a.outbound.createsend.com

These servers either use no transport encryption or TLS encryption with weak ciphers:

  • mx147.g.outbound.createsend.com
  • mx35.b.outbound.createsend.com

It would be really nice if this could be fixed.

Thanks and kind regards.
