250 pail.sin1.netline.net.uk Hello xxxx.ngi.it [xxx.yyy.zzz.aaa]
mail from: <>
250 OK
RCPT TO: gavin-collins@???
[a long pause from the server, presumably tarpitting]
550 Invalid use of null sender
rset
250 Reset OK
so the error is actually to RCPT. Or is RCPT not a synchronisation point?
I think I am going to rewrite the callout, as I already mentioned

that getting rid of it is the only one, but please don't start).
