Changes with nginx 0.6.12 21 Sep 2007

*) Change: mail proxy was split on three modules: pop3, imap and smtp.

*) Feature: the --without-mail_pop3_module, --without-mail_imap_module, and --without-mail_smtp_module configuration parameters.

*) Feature: the "smtp_greeting_delay" and "smtp_client_buffer" directives of the ngx_mail_smtp_module.

*) Bugfix: the trailing wildcards did not work; bug appeared in 0.6.9.

*) Bugfix: nginx could not start on Solaris if the shared PCRE library located in non-standard place was used.

*) Bugfix: the "proxy_hide_header" and "fastcgi_hide_header" directives did not hide response header lines whose name was longer than 32 characters. Thanks to Manlio Perillo.
