Sending emails - Going to spam folders
I have installed and configured scalix with sendmail, spamassassin and clamav. Sending emails working ok but when I send an email from a new user account to an outside email (like yahoo, gmail etc...) they are receiving it in the junk mail. When from the outside email (yahoo, gmail etc...) tick that that email is not spam, next time I send emails from the same scalix user account to the same yahoo email will go to inbox.
Can anyone please tell me why the first email is going to spam folder and how can I resolve it please?
Thanks. Your help is much appreciated!
