dovecot/original-hg/dovecot-1.2: src/master/login-process.c annotate

annotate src/master/login-process.c @ 1273:2cf2e08a6ee9 HEAD

Somewhat working code to support loading Dovecot from inetd and such. It still needs possibility to specify which login process to use, and LOGIN and AUTHENTICATE commands shouldn't be allowed before we're connected to auth process.
