Can anyone send emails to @yahoo.com using MailHop Outbound? It's been working fine for me for over a year, and suddenly stopped working today.

When you say "stopped working" - exactly what's happening? If it's a rejection message, can you provide the full details (obscuring addresses as appropriate).

I initially thought Yahoo.com was rejecting the messages, but it turns out it is still delivering them, but with a 20-30 minute delay. I looked into the support on dyndns some more, and it sounds like yahoo may be "greylisting" mailhop.org - that is, to prevent spam, it delays messages instead of rejecting them.
Yahoo are well known, along with Hotmail, for "creative" mail filtering. I'm not surprised they're now greylisting.
Up to 2 attachments (including images) can be used with a maximum of 524.3 kB each and 1.0 MB total.
For official support from Dyn eCommerce Support, upgrade your account to DynDNS Pro.
