This chapter contains basic information about how to set email clients (i.e. programs used to read and write email messages). It does not focus on particular client software but gives you general advice that you should follow in order for the client to work properly with Kerio MailServer.
An email account is a group of parameters describing the incoming and outgoing mail servers and the conditions for their use. Most email clients allow switching between multiple accounts. Let's create a new account that will be used for retrieving and sending messages via Kerio MailServer.
Note: The following description of settings was created using the MS Outlook Express 6.0 email client. However, basic account settings are very similar in all email clients.
This address should consist of the name of the user and the domain as it is set in Kerio MailServer, e.g.
This can be anything as it is only displayed in the message header. Using special characters (typically in non-English versions) might cause problems.
It does not relate to the full name or description in Kerio MailServer. A decent user sends messages using his/her own name!
DNS name or IP address of the host where Kerio MailServer is running (e.g.
IP address or the DNS name of the host on which Kerio MailServer is running (e.g.
POP3 or IMAP. If both services run on Kerio MailServer the user can choose whichever suits him/her best. The protocol type cannot be altered later. It is important to realize that if the user accessed the account using the IMAP protocol and now he/she wishes to use POP3, he/she will only be able to download messages from the INBOX folder.
The name and password for the Kerio MailServer user account. If the account is not in the primary domain a full email address must be used for the user name.
This needs to be set if anti-spam protection is enabled in Kerio MailServer (see chapter 13 Antispam control of the SMTP server) as well as relay control — sending email to any domain is not permitted from the client's IP address (see chapter 13 Antispam control of the SMTP server). If this is not set the user will only be able to send email within the local domains.
These options define whether a non-encrypted or an SSL-encrypted connection should be used during sending or receiving of email. With Kerio MailServer you can use a secured connection in both cases (if appropriate services are running), which is recommended.
This function can be used if a user logs into an NT domain and the user's account in the Kerio MailServer is set to authenticate the user in the NT domain. This allows the client software to use the same authentication credentials as the ones for logging into a domain.
You can use the Kerio MailServer LDAP server as a directory service (for details refer to chapter 21 LDAP server).
After creating a mail account using the IMAP protocol the client will download a list of folders from the server and display it. The user can choose the folders that are to be displayed (this can be changed later). In the client software the user can create, rename or delete folders in the same way as in the Kerio WebMail interface. It is important to note that these folders are stored at the server and not locally as with POP3 protocol.
It is important to ensure that the email client and the Kerio WebMail interface use the same folder names for sent mail (Sent Items) and draft messages (Drafts).
The email client can set synchronization for each folder. If a folder is synchronized with the server, each new message will be immediately displayed in the client software. This requires a permanent connection to the server. If the client is connected using a dial-up line, synchronization can only be performed manually or in defined time intervals.
