Our RoundCube installation defaults to having From Addresses @sonoracomm.com.

All users of RoundCube Webmail should verify and configure their Identity settings:

RoundCube → Settings → Identities → Your Default Identity

• Your Full Name
• Your Correct E-Mail Address
• Select Default (to make this your default identity)
• Signature (if desired)

You can create additional identities with different From Addresses (aliases) if you have them or want to send mail as another identity (i.e. Sales Department, etc.)

• Outlook 2003 does export multiple contacts to .vcf.
• Outlook 2007, 2010 does not.

Select “Address Book” icon and then “Import Contacts” icon. Browse to .vcf file for import.

A work around is to export the contacts to a CSV file then convert that to a .vcf file with this
