Добрый вечер, коллеги!

На Ubuntu14.04 установлен Postfix+Amavis-new как front-end(релэй) перед Exchange2013, спам помечает корректно но удалять его не хочет. Вопрос такой, почему?

Выдержка из 20-debian_defaults:

$log_recip_templ = undef;    # disable by-recipient level-0 log entries
$DO_SYSLOG = 2;              # log via syslogd (preferred)
$syslog_ident = 'amavis';    # syslog ident tag, prepended to all messages
$syslog_facility = 'mail';
$syslog_priority = 'debug';  # switch to info to drop debug output, etc

$enable_db = 1;              # enable use of BerkeleyDB/libdb (SNMP and nanny)

$sa_local_tests_only = 0;    # only tests which do not require internet access?

# Quota limits to avoid bombs (like 42.zip)

$MAXLEVELS = 10;
$MAXFILES = 500;

$MAX_EXPANSION_QUOTA = 300*1024*1024;  # bytes
