ZixCorp has released a new version the ZixMail Standalone client. This version has added some new features which address issues that some customers experienced when trying to connect ZixMail with their ISP's mail server. In addition, this version no longer supports the option for using the ZixMail HTTP/SMTP relay to deliver mail.
To download the new ZixMail Standalone client, go to the download section of the Zixcorp Support Center.
