Email synchronisation problem

Sync Issues
#1

I’ve an own domainname and webhosting space with Netmatters.nl.

Now I’ve made my own email address: name@mydomain.be.
In mailspring I want to see my emails from gmail and from ‘mydomain’. With gmail account no problems but with mydomain I must every time at restart mailspring go to settings => accounts => put in the email password for smtp and imap.
can someone help me what i do wrong?

Platform: win32
Account State: sync_error
Account Provider: imap
IMAP Server: mail.harmonieverbroedering.be
SMTP Server: mail.harmonieverbroedering.be

What happens if you don’t enter the password (rather than the logfile) - do you seen an error or does the account not update or something else? What settings apply to this account (imap and smtp ports and configuration, especially security e.g. TLS/SSL)? Have you tried other settings, to see if they help?
