Actual logs (pastebin'ed unless short) make debugging things a tad easier. What are you seeing on InspIRCd's end for logs or snotices (enable the appropriate snomasks).
At a glance, the Anope uplink block looks fine.
I'd try adding the 'sendpass' line to InspIRCd's link block (same password). Actually, a look at the source shows you should be able to use a single line of: password = "..."
Also (unrelated to current issue) your uline is incorrect. "services.host" will be read literally by InspIRCd, either set it to the actual name or read up on InspIRCd's define tags.
