[westaz]

How can I set a Vacation Auto-Response to send out a response to every email that i receive while i'am away or i'am not going to be able to respond to email ?

Please help me



I know that i must configure my server to send an email as auto-response but i'am newest on using roundcube so i dont know how can i change the interface of roundcube client to add an area to enter a subject for my auto-response email and the body of the email.

 Please help me and Thank you in advance .
