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.

Hi Upworkers, Our production Zimbra is 8_5, currently it's ussing SSL 3.0 and other depreciated ciphers need these disabled, backups taken first of the files then fix applied (either manually or automatically) https://wiki.zimbra.com/wiki/How_to_disable_SSLv3 from the vulnerability scan: Apache If TLSv1.1 or TLSv1.2 are available, then those protocols should be used. SSLProtocol TLSv1.1 TLSv1.2 If TLSv1.1 and TLSv1.2 are not available then only TLS1.0 should be used: SSLProtocol TLSv1 Typically, for Apache/mod_ssl, httpd.conf or ssl.conf should have the following lines: SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM Cheers Dave
