The string is expanded. So given that the rules are the same, you can
use:
[EMAIL PROTECTED] "${if def:h_from:{${address:$h_from:[EMAIL PROTECTED]" Ffs
(warning: untested and I no longer use any rewrites so am rusty on
those)
Exim quite happily uses multiple rules but you need to avoid giving it
bad rules. However, you can fail the expansion to force it to continue;
The Exim Specification, 31.6, "Rewriting replacements":
----------------------------8< cut here >8------------------------------
If the expansion is forced to fail by the
presence of "fail" in a conditional or lookup item, rewriting by the current
rule is abandoned, but subsequent rules may take effect. Any other expansion
failure causes the entire rewriting operation to be abandoned, and an entry
written to the panic log.
----------------------------8< cut here >8------------------------------
So yes, you can do:
[EMAIL PROTECTED] "${if def:h_from:{${address:$h_from:}}fail}" Ffs
[EMAIL PROTECTED] "[EMAIL PROTECTED]" Ffs
