Most of RBLS are checking the SMTP Banner and currently only the first domain name is being used. To reduce scamming or to prevent being blacklisted you should apply myhostname with the according domain name.

Add a new Domain/Subdomain-Type "DynDNS", which redirects to a dynamic IP-Address like dyndns.org and similar sites including an api to sync the current ip address through url call.

autodiscover for email settings for linux and windows

Add Sogo as a webmail alternative in Plesk.

Sogo share your calendars, address books and mails in your community with a completely free and open source solution

Sogo is a great webmail solution and provides native Microsoft ActiveSync support. Mobile devices such as Apple iPhone, Android, Windows Phone, and BlackBerry 10 can fully synchronize emails, contacts, events and tasks with SOGo.

Add subdomains to one Let's Encrypt certificate.

Why?

Because Let's Encrypt has currently limit 5 certificates / 7 days on one domain.

Example: in one Let's Encrypt cerftificate will be this DNS names: example.com; www.example.com; sub1.example.com; sub2.example.com

I think it will be helpful if you can simply add your own domains and subdomains in Let's Encrypt Certificate.

Thanks!

Please, add support to asp.net core in plesk 17 for linux.

Support varnish cache.

Many mail servers have this feature. Please include in plesk possibility to add disclaimer to mail footer on specified domain.

Many Clients ask me how to add Disclaimer to mail footer automatically not from webmail.

I'll like to create a hosting that only use Nginx as webserver. Also I'll like to do this with Node.js, but I think it will not be approved.

I suggest you add a feature in Settings with which we can enable SPAM / VIRUS protection for newly created mailboxes by default.

Add a function to include Owncloud in Plesk, so administrator can configure for each customer a specific cloud-space.

Allow management of greylist filters and configuration from the Plesk control panel instead of only from command line as is currently the case.

if you would manage multiple Plesk servers that function very appropriate

Some of security configuration requires GeoIP detection. It also useful for tracing and should be easy as adding '--with-http-geoip-module' option to configure command for the package.

It's incredibly annoying that you have to setup a subscription solely for each subdomain that you want to create email addresses for. Please fix this.

If you have a lot of subdomains, you may want to combine them into a single certificate, up to a limit of 100 Names per Certificate. Combined with the above limit, that means you can issue certificates containing up to 2,000 unique subdomains per week. A certificate with multiple names is often called a SAN certificate, or sometimes a UCC certificate.

letsencrypt allow this as mentioned on https://letsencrypt.org/docs/rate-limits/

Plesk team should implement this feature as soon as possible

We have many support requests from our customers (non technical) to search logs and find if a message was sucessfull delivered and consume much from our support.

If the customer could search logs from a specific sender ou destination, filtering by date, will be great for us.

Hello,

is better if such as "wordpress toolkit" you implement this software in plesk https://www.rfxn.com/projects/linux-malware-detect/ + ClamAV (is more faster the maildect search).

With this way, anyone can scan our website from malware. And after scan, the user need to have an notify via email or directly into plesk. This inscrease the security of website and also increase the plesk security.

I use it somethimes for scan all website into our web hosting, and I found it very usefull for prevent serius problem of botnet, hacked website etc.

I hope that you can consider to implement this function.

Regards

You are currently not able to Alias a subdomain through plesk. Instead you must create the subdomain as a primary if you wish to alias it. In many situations it would make sense from an organizational standpoint to keep the subdomain under a main domain while still adding aliases to it. I do not believe this is a technical restriction of the webservers so it would be helpful if plesk allowed you to add aliases to subdomains.

Certification Authority Authorization (CAA), defined in RFC 6844, is a standard that allows domain name owners to control which CAs are allowed to issue certificates for their properties.

ssllabs.com has implemented the detection for this record when checking for the SSL grade they give. To prevent getting graded down and use state of the art techniques for ssl security I would usggest to allow adding those nameserver record.
