    • Mail Security: Check ZIP / Archive files for blocked extensions

      I need, for example, to block exe files. however, the problem with ASG is that if files with blocked extensions are zipped - even without password protect the archive - they pass, because apparently Astaro only checks the zip file extension (rar, zip) and not the extensions of the files inside the archive, which means that you can bypass the blocking of any files by zipping them first. My only option now is to block zipped files which is not so practical as they may contain legitimate content that I don't want to block.

      • SMTP: Multiple Hostnames/Interfaces Support

        With the SMTP proxy able to handle mail for many domains, allow the proxy to be configured so that an admin can assign a hostname per profile, or have the proxy report different hostnames per outgoing interface. (and the ability to specify which domains/profiles go out which interface). Allows for easier management and adoption of many smtp domains on a single asg appliance.

        • MailSecurity: support SMIME Domain Certificates for encryption

          Being able to encrypt all emails of a specific domain with only a single certificate. This makes message based email encryption an lot easier and astaro more compatible with other email encryption players

          • Mail Security: Granular Encryption Control

            If a user is enabled to use mail encryption there's currently only the option to sign all of their outgoing mail or nothing.

            I'd like to have another option to sign only mails for listed recipients (single [billg@microsoft.com] or domain [*@astaro.com])

            • Encryption: Logging for this Feature

              Please add logging for email encryption / signing feature in Astaro. Actually there is no logging of decryption of incoming mails or encryption / signing of outgoing mails.

              • Mail Protection: Attachment Stripping

                currently, there are several "action" options in the smtp anti-malware section: warn, blackhole, quarantine, and reject.
                We should have a "remove attachment" option which means the unwanted (infected or dangerous) attachment is stripped off the mail, but the rest of the mail is forwarded to the recipient.
                Two things are achieved with this: the recipient is informed immediately about the mail (he doesn´t have to wait for the next quarantine report). And he can see that a mail from a possibily importand business contact has been blocked and see at least the "uncritical" content

                • Use Perfect Forward Secrecy for SMTP Proxy

                  Use PFS for SMTP Proxy, now it still supports RC4 which is a very weak Cipher.

                  • Mail Protection: Configurable SMTP Retry Timeout

                    A feature to allow administrators to reduce the SMTP relay Retry Timeout Limit would be excellent. Very useful for freight business who rely on email to get CON notes out quickly.

                      • Mail Protection: CRL for email encryption Certificate Authority (CA)

                        Using the ASTARO builtin Certificate Authority (CA) for creating certificates for external mailboxes, you should have a CRL (Certificate Revocation List) for certificates that have been revoked or are no longer valid, and therefore should not be relied upon. It is like the CRL you can use to disable a certificate in the "Remote Access" section of the ASG.

                        • Mail Security: Auto-whitelist Recipients of Outgoing Email Messages

                          All emails sent by internal users or from internal mail servers have their recipient addresses added to the MailSecuriy's whitelist.

                          That way if you send someone an email, you know that their reply will not be blocked.

                          • Mail Protection: Configure Interface/IP SMTP proxy listens on

                            Enabling the mail-security features presently opens up a massive surface area on all interfaces and ips. I would like to see the mail-security feature include a more assignable approach where we can choose what interfaces/ips the mail-security will bind to.

                            As we are a hosted service provider, the all or nothing functionality currently available is not ideal.

                            • Mail Security: Show Deferred Mails in Mail Manager/UserPortal (eg. Greylisted)

                              If a incoming Mail is delayed by Grey listing, this is not viewable in the Mail Manager. This is a Problem in Environments where End users really use the End User Portal for tracking their Mail.
                              In the End it has to be reviewed by the Admin again because you can only find out these Mails in the smtp-proxy Logfile.

                                Troubleshooting SMTP Smarthost problems with authentication is hard to do. After changing config you need to send test mails to an outside domain and have to watch logging.

                                Please add a test-button that can report:
                                1. no connection (IP:Port not listening)
                                2. connected, but user unknown (550)
                                3. connected, but wrong password
                                4. success

                                • Mail Protection: Forward POP3 Emails via SMTP to internal Server

                                  There are still a many customers out there which use POP3 Mailboxes. If a customer want's to connect these POP3 mailboxes to an internal Microsoft Exchange server, they always need to purchase an add-on tool which needs to be licensed on a per user basis. The tool downloads the POP3 Emails and forwards them 1:1 to the internal Server via SMTP. Each POP3 Mailbox needs to be configured via server, username and password and an SMTP email address where the email gets forwarded to.. Integrate this add-on feature and minimize the cost and effort needed to install, manage and maintain…

                                    • Mailsecurity: Hide internal IP in Mailheader

                                      It would be nice if the SMTP Proxy is removing the internal IP address in the "received from" line in the mailheader.

                                      Header with private IP
                                      Received: from mailsrv ([192.168.0.10]:2994) by asg with esmtps (TLSv1:AES256-SHA:256) (Exim 4.69)

                                      Header without private IP
                                      Received: from mailsrv (unverified) by asg with esmtps (TLSv1:AES256-SHA:256) (Exim 4.69)

                                      • Mail Protection: SMTP Mail Address Rewriting

                                        It is often useful to forward or rewrite incoming mail domains or specific email addresses to a user or usergroups. It would be great if the feature would be possible. For example *@domain-A.de forward to hans.muster@meinefirma.de, or all messages from info@domaene-B.de forward to Felix.Hubert@meinefirma.de,

                                        • Mail Protection: Add "delete" and "blacklist" buttons (to the current "release" and "whitelist") to quarantine digest email

                                          This would make user blacklisting significantly easier and reduce the amount of email held in the quarantine .
