If you run Zimbra mail service and would like to get EML copies of your messages, use Total Webmail Converter. This program works with lots of online mail services and can extract messages for local use. You can convert Zimbra emails to EML format to have the backup of important messages or share them as attachments to other mails.
Total Webmail Converter offers a user interface very similar to common mail clients like Thunderbird or Outlook. All mailboxes connected to the program are listed in the left navigation tab. To connect a mail account you need only to specify address and password in the "Add new" dialogue (from Accounts menu). After this Webmail Converter will quickly import all mail folders and you will be able to select messages for conversion. This is a batch converter, so you can export emails to EML very quickly, selecting the entire inbox or another folder for conversion. You can do it in four simple steps:
Click on "Inbox" or another folder on the left tab
Click on the "Select All" option at the bottom of the message list
Press "EML" on the top
Specify the conversion settings and press "OK".
Settings are optional and serve for optimizing the format of converted files. The program will save Zimbra mails as EML files and open destination folder automatically.
You can perform single mail conversion as well. For this just tick off the required message in the list and repeat steps 3-4. Besides converting you can use this EML converter as a mail viewer. It is integrated into the program and shows messages just like in your native mail app.
Total WebMail Converter is a shareware tool. You can download a trial demo first and use it 30 days for free. Get your copy here.
