Emailchemy for Linux converts email from the closed, proprietary file formats of the most popular email applications to standard, portable formats that any application can use. These standard formats are ideal for long term archival, database entry, or forensic analysis and eDiscovery. Emailchemy includes an embedded IMAP mail server from which any IMAP-compatible email application can import your converted email. Emailchemy includes a utility for uploading converted mail up to a Google Apps email account.
