Advantages and Disadvantages of using Mulberry

This page is for user comments about what they feel are the good points and bad points about Mulberry - good points come first! The overall story is that Mulberry is technically excellent, and fully featured, but the user interface could be simpler.


  • Excellent IMAP support
    • ability to share mailboxes (most other IMAP clients can access shared mailboxes, but can't grant access to them)
  • Handles large, high volume email accounts easily
  • Multiple identities with inheritance of attributes including address, signature, sent mail folder, server accounts, etc.
    • associate identities with specific mailboxes
  • Marks email read as soon as it's opened, or after a delay
  • Allows signing multiple identities with the same security certificate
  • Simple enterprise deployment using IMSP
    • Support for IMSP address book server - access the same address book from any machine or from web mail.
    • Support for IMSP preferences server - get the same preferences on any machine.
    • Display preferences are stored for specific screen sizes.
  • Almost unlimited options allow excellent personalization
  • Inheritance-based configuration of folders, accounts, and identities
  • Message editor with useful text reflowing options, eg., reflowing quoted text
  • Supports multiple message alert and checking styles that may be assigned to specific mailboxes
  • Has plugin support for PGP and GnuPG (PGP/MIME and identity specific options also supported)
  • Integrated S/MIME support
  • Multiple SMTP server support both at account and identity configuration levels.
  • Ability to define custom headers for identities
  • Ability to choose, at message composition/send time, where the outgoing message will be filed, and (for replies) to optionally also re-file the message being replied to.
  • Full support for SSLv3 and STARTTLS for POP, IMAP and SMTP
  • The excellent configuration tool that was available up to version 4.0.4 is now available for 4.0.5 or 4.0.6. The tool is great for customisation and enterprise deployment.
  • Doesn't render graphical attachments inline :-) (i.e. automatically avoids the insecurity of web beacons, doesn't waste bandwidth by default).
  • Sensible support for multiple accounts, i.e. each account's login status is separate, so you are able to login to server A without logging into server B (try that in clients that only support a global online/offline mode).
  • Summary view of message counts (total/new/recent) in mail folders (other clients with folder tree views only seem to display folder names, and (if you are lucky and you poll the folder) the number of new messages).
  • Can provide an alternative to the three-pane view that seems to have become the default for email clients.
  • Sensible support for navigating large folder hierarchies (try using the folder subscribe feature of other clients when you have more than 1000 IMAP folders, or try adding your personal gigabyte mail archive to a client that insists on indexing every message before you start using that server).


  • Doesn't render graphical attachments inline (see above for why this is arguably an advantage).
  • Single-threaded (so you can't get on with writing an email while Mulberry is checking for new mail).
  • Keystrokes not configurable
  • No localisation
  • Configuration in multiple places (eg. Preferences, Windows menus) is confusing
  • Complex user interface.
