Recently signed up for MXRoute, which mostly seems to work well as advertised. I migrated emails to MXRoute via
TransferMyEmail and it duplicated most (but not all) of the emails, just about doubling the size of my Inbox on MXRoute. I migrated the emails from a Gmail account and made sure not to select the All Mail folder and I had all labels turned off too. In any case, does anyone have any good ideas on how to dedupe thousands of emails? I have been using Horde, but I could switch to Roundcube or Squirrel if that makes a difference.
