PIX 7.2(1) We have trouble with incoming mail. Sometimes it comes through later. ESMTP inspect is set lo low security (just log) but something seems to be wrong since the PIX still mangles the server banner even though that setting is unchecked in ESMTP inspect. The above log entry comes immediately after the "Built inbound conn...." message. Some bytes seem to get through, according to the "Teardown..." messages. The majority of mail gets through.
