Hi Sunil,
Mark as best answer, If it resloves !!
Please check below code it works on contact email matchs with lead email it will show error 
Trigger leadTrigger on Lead(after insert, after update) {
    Set leadEmails = new Set();
    for (Lead l: trigger.new) {
        if (!l.IsConverted && null != l.email && '' != l.email)
            leadEmails.add(l.email);
    }
    Set contactEmailMatches = new Set();
    for (Contact c: [SELECT Id, Email From Contact where Email IN: leadEmails]) {
        contactEmailMatches.add(c.email);
    }
    for (Lead l: trigger.new) {
        if (!l.IsConverted && !l.OwnerId.startsWith(Schema.SObjectType.QueueSobject.getKeyPrefix())) {
            if (contactEmailMatches.contains(l.email)) {
            } 
        }
    }
}
