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

annotate src/master/login-process.c @ 1610:6850142c4e25 HEAD

New configuration file code. Some syntax changes, but tries to be somewhat backwards compatible. SIGHUP now reverts back to old configuration if it detected errors in new one.
