APEWS: E-361935 / 65.74.185.26 most certainly is *not* dynamic, and it *does* have a valid PTR.

I'm a sysadmin for EngineYard. We have no dynamic IPs of any kind,
and we immediately disable all spammer accounts; we in no way help or
support spammers.

Oooops 65.74.185.26 is currently listed in APEWS :-(

It is not a dynamic IP. It has a valid PTR. I have no idea what
"generic DNS" means.

$ host 65.74.185.26
Name: smtp.zendesk.com
Address: 65.74.185.26

We've got a legitimate customer (zendesk is a bug tracking tool),
sending legitimate mail, blocked by APEWS. Is there anything we can
do?

Looks OK to me. I'd say the listing is in error. I'm sure there are many
similar errors - APEWS isn't noted for accuracy.

I have no idea what "generic DNS" means.

That's rDNS that seems to be generated from a template rather than
actually identifying the host, e.g., node8.173.136.64.1dial.com.

APEWS isn't blocking anybody. If the recipient's mail server is using
APEWS, contact him offline and suggest that he ask his admin for a
whitelisting. Meanwhile check all of the IP addresses in the block for
generic rDNS.
