Setting Email Clients
Setting Email Clients
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.
Setting an Email Account
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 Microsoft Outlook Express 6.0 email client. However, basic account settings are very similar in all email clients.
- Outgoing (personal) email address
- This address should consist of the name of the user and the domain as it is set in Kerio MailServer, e.g. smith@ourcompany.com.
- Name of the user
- 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!
- Outgoing mail server (SMTP)
- IP address or the DNS name of the host on which Kerio MailServer is running (e.g. 192.168.1.1 or mail.ourcompany.com).
- Incoming mail server
- IP address or the DNS name of the host on which Kerio MailServer is running (e.g. 192.168.1.1 or mail.ourcompany.com).
- Incoming mail server type
- 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.
- User name and password
- 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 is not possible in the primary domain!).
- Authentication on the outgoing (SMTP) server
- This needs to be set if anti-spam protection is enabled in Kerio MailServer and sending email to any domain is not permitted from the client's IP address (see chapter Antispam Protection of the SMTP Server). If this is not set the user will only be able to send email within the local domains.
- Server requires secure communication
- These options define whether a non-encrypted or a 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.
- Secure password authentication (SPA/NTLM)
- This function can be used if a user logs into an NT domain and his/her account in Kerio MailServer is set to authenticate the user in the NT domain. Then there is no need to set the password in the client software, as domain authentication will be used instead.
Directory Service
You can use the Kerio MailServer LDAP server as a directory service (for details refer to chapter LDAP server)
IMAP Folders Administration
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!
Furthermore, 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.
