I have a question about milter in postfix 2.5.1

It seems that macros {mail_addr} don't returned in xxfi_envfrom callback.

To test was used milter with callback:

sfsistat
mlfi_envfrom(SMFICTX *ctx, char **argv) {
         char *mail = smfi_getsymval(ctx, "{mail_addr}");

         if (mail == NULL ) {
                 mail = "NULL pointer";
         }

         printf("{mail_addr} = %s\n", mail);

         return SMFIS_CONTINUE;
}

In postfix 2.4.5 it work fine and print:

{mail_addr} = xxxxxcitrin.ru

In postfix 2.5.1 it fail to get {mail_addr} and print:

{mail_addr} = NULL pointer

$ postconf milter_mail_macros
milter_mail_macros = i {auth_type} {auth_authen} {auth_author} {mail_addr}

Debug log from 2.4.5:

postfix/smtpd[62856]: report sender to all milters

test milter was build with libmilter from freebsd 6.2 base system (sendmail 8.13.8)
