nginx 0.5.15 *) Feature: the mail proxy supports authenticated SMTP proxying and the "smtp_auth", "smtp_capablities", and "xclient" directives. Thanks to Anton Yuzhaninov and Maxim Dounin. *) Feature: now the keep-alive connections are closed just after receiving the reconfiguration signal. *) Change: the "imap" and "auth" directives were renamed to the "mail" and "pop3_auth" directives. *) Bugfix: a segmentation fault occurred in worker process if the CRAM-MD5 authentication method was used and the APOP method was disabled. *) Bugfix: if the "starttls only" directive was used in POP3 protocol, then nginx allowed authentication without switching to the SSL mode. *) Bugfix: worker processes did not exit after reconfiguration and did not rotate logs if the eventport method was used. *) Bugfix: a worker process may got caught in an endless loop, if the "ip_hash" directive was used. *) Bugfix: now nginx does not log some alerts if eventport or /dev/poll methods are used.
