Roundcube allows you to export all your contacts in a single VCF file. Unfortunately Smartermail is too stupid to see more than the first contact. You need to convert the VCF file to CSV and you can then easily import your contacts into Smartermail. This will work with ANY system that exports multiple VCF cards in a single file
Login into your RoundCube Webmail
Click on Contacts
Click on Export in upper Left - this downloads contacts in vcard
