Hi , I have enabled a new mail account for myself via the control panel , test it from webmail and then add it to Thunderbird on my system .
It checks mail without problems but when I want to send mails this error returns ;

Complete translation of the Turkish message ;
Error occured while sending mail . Mail Server Returns : Dynamic/Residential IP Range listed by NJABL Dynablock - njabl.org . Please check the e-mail address under mail settings and try again.
What is this ?
Are we or our mailservers blacklisted again or I’m missing something 
All my thunderbird settings are correct , my other accounts (from other mailservers different than Jodo) can send mails perfectly without errors .
How can we fix this …
Is this error can be related to JodoHost DSPAM system ?
Best wishes,
