Hello
we checked the user/password are correct
the 996 port is open on telenet
the server uses ssl
in fact to reproduce the problem we installed a test paltform with projeqtor is hosted on our cloud provider intersever and we got the same problem
the test paltform adress is :
gsolutionsconsulting.org/projetstest/view/main.php
login : admin
password : password
the email address is: projet.gsolutionsconsulting.org
password : cisco2017gss
the adress of the imap server is either :
webhosting2021.is.cc
or
mail.gsolutionsconsulting.com
you can do the tests and reproduce the porblem.
we tried the same configuration on another imap server for another hoster Godaddy and we got the same results.
This feature is very ususfuland apractical for the project traceablity,
Thanks for your help and assistance

Hello,

Please check the mail scrip with the help of your developer. If he needs any changes to be made in the server in order to get this resolved, I'll get that done for you.

Kind Regards,
