@lucag would you also consider adding a re-direct feature for emails on webtop.
I think it will be an important Function
This useful in organizations in places where you want someone to take over the conversion withtout involving you.
You are able to redirect mails with rules:
I think the redirect that meant @oneitonitram was this:
“If you use redirection, your e-mail will be redirected to another e-mail address as if it came directly from the original sender’s e-mail address.”
It is not present in WebTop 5 and, if I’m not mistaken, it is not present in SOGo, Roundcube, Thunderbird and Outlook.
In any case, the @webtop_team can be asked to evaluate a possible implementation in the future 
Thank you. Thats the redirect I was talking about. I am glad you got it.
Its a very nice feature, especially if sales receives an email ment for IT. it can just be re-directed and all is well.
