Migration to IBM WTT Email Platform

[mikemls]

My ISP PIHK Email Service has migrated users to a so-called WTT platform without technical support. l cannot send nor receive emails from Seamonkey after changing the POP and SMTP settings. Although the old emails are still accessible. Same with the Samsung settings on my smartphone, cannot receive nor send emails. Appreciate any comments,
many thanks,
Michael
