No SBL hits on either of these relatively old domains. No NANAS hits on cellular-parts, 68 on poetry.
Please send one sample of each message.
I can vouch for poetry.com. I haven't had any mailings from them, but they are a legit site, and should probably be whitelisted. The NANAS reports also appear to be bogus; some contain the bare domain "poetry.com" in tiny font, and some link to images (e.g., of Robert Frost) on poetry.com, but, after looking at all the reports from this year, none actually advertise poetry.com.
In fact following another quick sanity check, I'll do more than vouch for them. I've whitelisted poetry.com (on WS). They should never be blocked in the first place.
