Introducing the e-mail system, we often mention: This e-mail system to accept the POP3 protocol, IMAP protocol, and these specific agreements that you know how much? Coremail off on proprietary protocols and proprietary protocols POP3, IMAP protocol there is a difference, after all, how? iis7 server monitoring tools in the end on the go? We look at the following definition:
Mail with encrypted data transmission, stating that POP3IMA P Coremail private agreement can not be done and can do Coremail proprietary protocol by using a variety of encryption transmission technology SSLPKI and so on. To achieve the anti-monitoring function. State support Encryption Standard algorithm, to ensure client-safe two-way transmission between servers. Optimization of the certification and processing decryption process, while achieving a rapid interoperability.
1.POP3 agreement
POP3 full name "PostOfficeProtocol-Version3 known as" Post Office Protocol version 3TCP / IP protocol suite is an explanation of Baidu Encyclopedia. Defined by RFC1939. This protocol is mainly used to support the use of e-mail client remote management on the server. SSL provides encryption POP3 protocol is called POP3S
E-mail client to call the mail client order to connect to the server, POP protocol support "offline" Mail disposal. The specific process messages sent to the server. And download all unread e-mail. This off-line access mode is a store and forward service, mail from the mail server to the personal terminal equipment, typically a PC or MA C-mail message is sent once to the PC or MA C, on the mail server will been deleted. But the most POP3 mail server can "only download mail, the server does not delete" is to improve the POP3 protocol.
2.IMA P Agreement
Download mail. Current authoritative definition is RFC3501IMA P protocol runs on top of TCP / IP protocol, IMA PInternetMailAccessProtocolInternet Message Access Protocol) and previously called Interactive Mail Access Protocol (InteractMailAccessProtocolIMA P Stanford University In an e-mail to obtain agreement in 1986 to develop the main role is the message the client (for example MSOutlookExpress can get information in the mail from the mail server via this protocol. the main difference is the port used by the POP3 protocol 143 is that users can not download all the messages of all, you can direct the client to the server mail operation.
3.Coremail proprietary protocols
Coremail proprietary transmission protocol uses a new codec technology, as compared with the conventional SMTP mail communication protocol. Mail delivery process is encrypted and compressed, effectively increasing the safety of the mail data transmission over the Internet, and a significant reduction in network traffic data, the transmission of plain text data, use CMTP agreement will enhance exceed twice the speed.
We have a basic understanding for these three agreements. Then use the actual function, what difference does it make?
First, account settings
You need to be set separately. Mail account or any mail folder, right-select "Mailbox Settings" or click on "Settings - E-mail settings" may be related to the account set email account. Mail account property is set for each account if there is more than one email account.
1. Account settings -POP3 mail account settings
You can set mail account name, email address, password, reply mail address, mail server. Using the POP3 protocol for the creation of the account when creating an account.
On the guest Coremail mail client will automatically search assistance, Note: The information 1POP3 mailbox servers in the account creation process. If some non-mailbox search results or set transceiver have a problem in the future (possibly errors search results) can search the Internet using the mailbox server or a letter of inquiry. 2 Fill in the e-mail address after the reply mail sent this email account, while the other replies will revert to reply in e-mail address set here.
2. Account Settings -IMA P-mail account settings
You can set mail account name, email address, password, reply mail address, mail server. Use IMA P protocol for the creation of the account when creating an account.
Try to find its corresponding server. Note: The server will automatically search for a matching account with POP3 protocol.
3. Account Settings -Coremail proprietary protocol account settings
Coremail private agreement with webmail account a series of synchronous functions, Coremail proprietary protocol created account mailbox settings "account settings under" has been confirmed for a good mail server. Just set up an account name, email address, password, and reply to e-mail addresses. In addition. This interface can be set up synchronization when letters disposal.
Second, the receiver set
Can be set according to their needs, set up the account option reception conditions. Get a different reception experience.
1. Set the receiving protocol account -POP3
Re-collect items not previously received "after receiving, 1 tick" next reception. We can not accept the first choice when the mail popping reception. 2 can be set automatically according to their reception interval; choose whether to keep the backup server on the guest -Coremail default mail client on the mail server keeps a backup, if you need to regularly delete the backup from the server, you can remove the tick or tick in the days after the election n delete, then delete mail from the server, that web page will not be there-mail messages (this operation need to be cautious)
2. Set the receiving protocol account -IMA P
Since the protocol is IMA P 1 and the server thus eliminating the need to close the remaining synchronization messages and keep the backup server. 2 and as POP3 protocol can be set automatically according to their reception time interval.
3. Set -Coremail receiving mail account private agreements
There are also special increase of some special settings: Coremail private mailbox settings have agreements in addition to receiving general mailbox.
1 may be provided only charge charged with unread; 2 may be set whether to collect custom message folders, spam, Drafts and Sent Items box messages; 3 charge time interval may be provided; 4 can be set automatically according to their reception intervals; 5 choose whether to keep the backup server.
Third, the letter set
1. Account signaling protocol provided -POP3
From senders signature displayed in the letter. When a letter signed by the sender can be set.
2. Set the transmission protocol account -IMA P
So without this in the settings. IMA P protocol sent messages is determined by mapping.
3. Set -Coremail letter mail account private agreements
Coremail proprietary protocols sent messages can be synchronized to save web pages;
From senders signature displayed in the letter; write may be provided if required receipt; transmit window is hidden can select transmission; can set whether to automatically keep messages sent to the Sent Items folder on the WebMail; can providing one or more default Cc; may be provided one or more default Bcc. When a letter signed by the sender can be set.
