We are running Zimbra 8.6.0_GA_1162.NETWORK on our VPS CentOS release 6.7. There are about 15 domains / 80 email accounts served by Zimbra. We are looking for a Linux and Zimbra expert for performing the following tasks on our server. 1. We have a backup script based on https://github.com/bggo/Zmbkpose/blob/master/src/zmbkpose which stopped backing up email accounts. We would like to have it running again every night and keep the mail backups for the last 7 days. 2. Upgrade the VPS OS to the latest Centos 7 stable release 3. Upgrade Zimbra and all packages/services it depends on to the latest stable release, and a sanity check on the system 4. I would like to have all notifications to myself (the zimbra admin) and to the various recipients originating from a dedicated account (postmaster@domain.com) rather than from my primary email account. 5. I would like to increase the maximum size of email attachments to 10 MB. (now it's about 7 MB). 6. I would like to have the SPF policy enforced by default for all accounts using the default COS. 7. As the zimbra admin I keep on getting emails with subject UNCHECKED contents in mail FROM [various IP addresses]. The body says No viruses were found. Content type: UncheckedOverLimits These emails are indeed relayed to the final recipients while should be blocked. The work should be possibly made during Italian night hours to avoid disruption.

We need to set up a multi tenant system for our clients so that they can have sites hosted on one server and and email on another. We want the setup to be automated so that virtual host information is added automatically upon account initiation. We also want to set up a separate email server that can host the clients' emails for multiple domains. We have the application working in PHP, so will need help setting up the email server and creating shell scripts that we can invoke with PHP to create and manage both the domain and email accounts. We've identified Zimbra as a good mail server option, but are open to better alternatives. We have left budget $5/$5000 so that you can bid based on the time you expect to spend on this task. Thanks.
