Any chance of getting the non-truncated error message, perhaps by
replicating at the { exim -be } command-prompt, or doing so with
debugging turned on?
Running exim -be:
> ${lookup dnsdb {>\n; txt=95.64.115.74}}
So, no output, looks fine.
The only way I've managed to get close to an error message is by trying:
> ${lookup dnsdb {>\\n; txt=95.64.115.74}}
Failed: lookup of ">\n; txt=95.64.115.74" gave DEFER: unsupported DNS record
type
Is it possible that the snippet you provided has different quoting in
the actual configuration than you cited above?
If things work at the { exim -be } prompt, then perhaps you could try:
exim -oMa 95.64.115.74 -d+acl+expand -bs
and then an SMTP transaction, to see the expansions happen?
