Hi.

As far as I understand, compilation of regular expressions in ACL's is
performed during config parsing. Therefore regexp can be compiled either
as extended or basic depending on position of the keyword
'extendedregex' in the config file.

Not sure what to do, but I think it should be documented or one should
put keyword 'extendedregex' in the beginning of sample config file. I
dont think this switch is useful at all. re_format(7) in FreeBSD calls
basic regex "obsolete" and says that it "mostly exist for backward
compatibility in some old programs".

I am using many ACL's based on client's hostname, so it is useful for me
to log hostnames along with "addr", "rcpt" and "from". If you also find
it usefull, see simple patch attached.
