-## Configuration Examples
-
-### IMAP Server with Connection Handlers
-
-```javascript
-const { IMAPServer } = require('wildduck/imap-core');
-
-const server = new IMAPServer({
-    // Connection filtering and rate limiting
-    onConnect: (session, callback) => {
-        // Block specific IPs
-        if (blockedIPs.includes(session.remoteAddress)) {
-            return callback(new Error('IP blocked'));
-        }
-
-        // Rate limiting
-        if (connectionCount[session.remoteAddress] > 10) {
-            return callback(new Error('Too many connections'));
-        }
-
-        console.log(`New IMAP connection from ${session.remoteAddress}`);
-        callback();
-    },
-
-    // Connection cleanup
-    onClose: (session) => {
-        console.log(`IMAP connection closed: ${session.id}`);
-        // Custom cleanup logic here
-    }
-});
-```
-
-### POP3 Server with Connection Management
-
-```javascript
-const POP3Server = require('wildduck/lib/pop3/server');
-
-const server = new POP3Server({
-    // Enhanced timeout handling (automatic)
-    socketTimeout: 300000, // 5 minutes
-
-    // Connection filtering
-    onConnect: (session, callback) => {
-        // Custom authentication logic
-        if (!isAllowedConnection(session)) {
-            return callback(new Error('Connection not allowed'));
-        }
-        callback();
-    },
-
-    // Connection monitoring
-    onClose: (session) => {
-        logConnectionStats(session);
-    }
-});
-```
-
-### CONDSTORE Usage
-
-```javascript
-// Enable CONDSTORE extension
-A1 ENABLE CONDSTORE
-
-// Conditional STORE operations
-A2 STORE 1:5 (UNCHANGEDSINCE 12345) +FLAGS (\Seen)
-// Response: A2 OK [MODIFIED 3,5] Conditional STORE completed
-
-// UID STORE with UNCHANGEDSINCE
-A3 UID STORE 100:200 (UNCHANGEDSINCE 67890) FLAGS (\Deleted)
-// Response: A3 OK [MODIFIED 150,175] Conditional STORE completed
