 The VPOP3 Host Name is used by VPOP3 when it is telling other mail software what it is called. For instance, when it connects to another SMTP server it will send the host name as the parameter for the HELO or EHLO command, and when an SMTP client connects to VPOP3, it announces its name in the welcome banner as required by the SMTP standard. The VPOP3 Host Name is used by VPOP3 when it is telling other mail software what it is called.

It is rare for ISP SMTP relay servers to check this because they use more reliable forms of authentication. (Note that the SMTP standards strictly prohibit the receiving mail server from blocking mail if the host name is set incorrectly).
