Email to your address is being returned undelivered. I have no
idea why. Yours is the only address that fails and I have made no
changes to my email configuration. I'm replying on the list to make
sure you see my replies.

.SP (or the groff request .sp) adds the current linespace (\n[.v]) to
the requested distance when | is used, for which compensation needs
to be applied:
.SP |(\\n[tmp]-\\n[.v])u
I would also suggest protecting the request by disabling vertical
position traps:
.vpt 0
.SP |(\\n[tmp]-\\n[.v])u
.vpt
