11:41:08 Well... I must have missed a couple steps... the fax app is returning "554 not found" for the recipient. I'm assuming it isn't finding the dynamic domain. Any suggestions on where to look or what I may have forgotten to do? 16:57:22 should be faxbox config, custom domain or similar; 20:13:48 Ysean: re-reading; perhaps have a gander at the fax box via API and confirm your settings?
