I am administering a domain for a client in ISPConfig 3.15. My task is to configure a mail address that should: 1. automatically reply to all incoming mails and (this feature is called *Autoresponder*) 2. forward all incoming mails to a list of mail addresses. Configuring the mail address that way works up until a certain point: When I enter the list of mail addresses for forwarding and confirm this, I get the following error: Data too long for column 'cc' at row 1 As a workaround I tried the following: I configured the mail address in ISPConfig but did not enter any mail addresses to forward. I then went to the webmail client (Roundcube) and tried to configure the forwarding there. I could enter a few mail addresses, but after the seventh or eighth I get the same error as before, just with slightly more details: Soap Error: Data too long for column 'cc' at row 1 UPDATE `mail_user` SET `server_id` = '1', `email` [remaining SQL statement follows] My question is: How can I configure a mail address in ISPConfig that forwards incoming mails to more than 7 or 8 addresses? I know that there is a separate feature in ISPConfig where I can forward mails to other mail addresses without having to create a mail account. However, then I cannot use the Autoresponder feature which I definitely need.
