nginx: src/mail/ngx_mail_smtp

annotate src/mail/ngx_mail_smtp_handler.c @ 7789:ab6257dac2a8

Mail: added missing event handling after blocking events. As long as a read event is blocked (ignored), ngx_handle_read_event() needs to be called to make sure no further notifications will be triggered when using level-triggered event methods, such as select() or poll().
