Review on Zimbra Converter by Mike Starling

It's fast for conversion of large files/email attachments as compared with other options in market like Eudora etc., but it needs good configuration setup initially to give best performance out there at this moment.

Support team help you very well during initial installation phase which can be tricky sometimes with others softwares too. So if your looking forward having such powerful converter then go ahead otherwise no need just skip that one! Have solved problems related file attachment conversions while migrating mailboxes (from zimba) into gmail account.
