Sure, if someone does it. Since you desire the feature, you seem to be
the right person for implementing it. And that's a good opportunity to 
learn about programming.

Quickly hacking it is not difficult, edit miller-greylist.c, and replace
SMFIS_TEMPFAIL by SMFIS_SUCCESS. You can even do a nicer hack by not changing
the occurence after the malloc failure (when you are out of memory, you 
temporarily reject until things get better).

The next step is to add a configuration option, which is a bit more complex,
but after all you just have to replicate what is already done for other 
options, such as noaccessdb. You have to edit the following files, duplicate
the lines where you have noaccessdb and replace noaccessdb by learnmode:
conf_lex.l conf_yacc.y conf.c conf.h

The remaining part is straightforward: replace your SMFIS_SUCCESS change by 
if (conf.c_learnmode) 
	return SMFIS_SUCCESS;
else
	return SMFIS_TEMPFAIL;

After this, be nice and add this new option to the man page (greylist.conf.5),
and contribute the result.
