It displays the email and then goes to say that it is sent "via yourhostingaccount.com"
have you setup your identity correctly in rc? (settings > identities)
what method are you using to send email - php mail() or SMTP?
Yes, I have setup by identity on roundcube. In the roundcube menu, there isn't much to set (Only Display Name, Email address, Organization, Reply-To, Bcc, Set Default, & Signature are available to set.) There doesn't seem to be any setting related to what domain it is sent from. I currently have the Display Name, Email Address, Organization, Set Default, and Signature set in the menu.
I have tried using both methods to send email.
Both of which, still contain the "
via yourhostingaccount.com" bit added in gmail. I have only been able to see one difference between the two methods. When using my hosting companies SMTP credentials, it seems that my emails are sent to spam. When using php mail() function, it doesn't seem to filter the email as spam.
This make me think that my hosting company may be blacklisted or something...
