smtpd_request_rec questions

[Garrett Rooney]

I was just looking at the smtpd_request_rec in mod_smtpd, and I had a 
few questions.

It seems that extensions and rcpt info is being stored in an apr_hash_t, 
but it's only being keyed by integer.  If you're only going to use ints 
as keys, it seems like an apr_array_header_t would be more appropriate. 
 Also, while the extensions has is specifically allocating its keys, 
the rcpt_to hash is reusing the r_index variable each time, so if more 
than one entry is added things aren't going to work, since that location 
in memory is having its value changed after its been used as a key.

Anyway, I'd be happy to produce patches to either switch to an array or 
fix the key issue in the rcpt_to section, depending on which way we want 
to go.  Personally, I'd prefer the array version though.
