## Implementation Guide
### Retrieve Message Summary Information Using Sequence Number
This feature allows you to access message details by specifying a sequence number assigned by the server.

### How can I retrieve email summaries using a sequence number?
Load the POP3 client, connect to the server, and call the `listMessages()` method to obtain a `Pop3MessageInfoCollection`. Then use `getMessageInfo(int sequenceNumber)` to fetch the summary for the desired message. This approach requires only a single network round‑trip per message and returns metadata such as subject, sender, and received date without downloading the full email body.

#### Initialize Your Client
Create an instance of `Pop3Client` and set security options:
Pop3Client is Aspose.Email's class for connecting to POP3 mail servers. Create an instance, configure host, port, username, and password, then set security options as needed:
```java
Pop3Client client = new Pop3Client("host.domain.com", 456, "username", "password");
client.setSecurityOptions(SecurityOptions.Auto);
```

#### Fetch Message Info Using Sequence Number
Retrieve message summary details using the sequence number:
`getMessageInfo(int sequenceNumber)` retrieves the summary of a specific email by its sequence number.
```java
String seqNum = "sequence number of a message from server";
Pop3MessageInfo messageInfo = client.getMessageInfo(seqNum);

}
```
- **Parameters:** Sequence number as a string identifier.
- **Parameters:** Sequence number as a string identifier.
- **Return Value:** `Pop3MessageInfo` object containing the email details.
### Retrieve Message Summary Information Using Unique ID
This feature is similar but uses a unique ID instead of sequence numbers to fetch message summaries.

### How can I retrieve email summaries using a unique ID?
Use the unique identifier (UIDL) that POP3 servers assign to each message. Call `getMessageInfoByUid(String uid)` to obtain the same `Pop3MessageInfo` without relying on server‑assigned sequence numbers, which may change after deletions. This method provides a stable reference to messages, allowing reliable retrieval even when the mailbox is modified.

#### Fetch Message Info Using Unique ID
Access message information via its unique identifier:
`getMessageInfoByUid(String uid)` returns the message summary associated with the given unique identifier, ensuring consistent access across sessions.
```java
String uniqueId = "unique id of a message from server";
Pop3MessageInfo messageInfo = client.getMessageInfo(uniqueId);
