The IMAP module now implements a new extension, QUOTA, as described by the RFC 2087 standard. IMAP clients implementing the QUOTA extension can display mail box quota for a specific user account. So far, users were able to find out what their current mailbox quota was (space occupied/total space) only via WebMail.
Listeners
Listeners can be defined and managed to add extra flexibility and configurability to this service. For that, global access limitations, SSL Settings and access lists can be enforced on the address used by this service for binding.Access Control
Access rules allow you to control connection to this service by defining simple access lists for specific Networks / IP Ranges / IP’s. Service level access rules are automatically applied to all its listeners and will override for this service any existing Global Access rules.Flow Control
Flow control parameters can be adjusted to fine tune the server’s performance and avoid overloading it. Global access limitations to this listener can be enforced by setting the total number of simultaneous connections, concurrent connections from each remote IP address, number of new connections to the listener made in a time period interval, number of total connections from each remote IP address on a time interval period. The default interval for this time period is set to 1 minute.Logging
All AXIGEN main services can log different types of events. The system administrator can specify what events are logged, where and how they are logged.See Logging service for more details on logging in AXIGEN.
Encryption and Authentication
Various authentication types can be used in AXIGEN for IMAP secured (SSL/TLS) / unsecured connections. Possible options are: normal login, plain, login, cram-md5, digest-md5 and gssapi. By default, all these methods are selected (all types of authentication are allowed).Error Control
To protect the server the number of failed/wrong commands, received from IMAP clients during one session, can be limited. When these limits are exceeded, incomplete connections or connections that are not RFC compliant will be dropped thus freeing important bandwidth.Important! If you do not specify a limit for the maximum number of (authentication) errors allowed for a IMAP client's session, security risks may arise.
Thread Management
AXIGEN Mail Server is designed to run on different machine configurations and operating systems, on networks with various traffic loads, structures, domain configurations, user rights etc. That is why, depending on all these variables, you can adapt the workload to the server’s processing power to improve its performance or avoid overload by setting the minimum and maximum number of threads that can be opened at a specific moment of time.Compatibility with various IMAP Mail Clients
AXIGEN has been thoroughly tested and it is proven to work with Mozilla, Outlook, Outlook Express, ThunderBird, The BAT!, Eudora. For information on how to set up your IMAP account, see the corresponding section of the AXIGEN website.Public Folders
Users may now share email messages by simply copying and/or moving them to a public folder. System administrators can also associate a certain email address with a public folder. Thus, emails can be sent directly to the public folder, archiving options being also available.Internationalized Search
When running an IMAP search for any IMAP client, the search text may contain language-specific characters (i.e. using diacritics).For more details on how to configure IMAP parameters using WebAdmin see IMAP Tab.
