Hi,
We updated recently some plesk to Onyx, and we have some problems with SRS. We send all mails through spamexperts and they send back with Error. 550 Verification failed. this occurs in one of the domains of this VPS (we can't validate all with same OP in spamexperts panel).

We opened a ticket with they, and they said that's a problem with plesk/postfix config, can suggested any idea? Thanks.

Plesk Reseller mail configurations are not funcitional anymore since hotmail and gmail move mails without SRS information directly to the user's spam folder. Most users ignore the spam folder's content and important mails are deleted!!! That is also true for United Internet - one of the major dsl and hosting providers in Germany (1&1, Web.de, gmx.de). This is not a feature - its a faulty implementation of SPF

SPF ist useless without SRS. You don't know if a recipient is forwarding your email and then perhaps SPF fails because his provider is a Plesk user. postsrsd does not work for me in conjunction with plesk and default configuration.

gmx.de and web.de enabled SPF - forwarding to their mailboxes results in an error. Please enable SRS as soon as possible.

Please Implement as JR's comment mentioned already that the biggest Mail Provider is now enforcing SPF!

Please implement SRS as soon as possible. We have many problems because of the activation of SPF by United Internet, a mayor mail provider.

Since biggest German email provider "United-Internet" enabled SPF by end of May 2016, there is the urgent need for SRS in order to make email-forwarding via Plesk servers working again!!!

United Internet (one of the largest German freemail provider: GMX and web.de) fully enforces SPF since 2016-05-25. Forwarding mails to these recipients is not possible any more. About 40% of my recipients can't receive mails from forwarder any more!
Please enable SRS!!

Many people probably don't even notice that some specific of their forwarded messages are not delivered. And typically, an invisible problem is no problem for the majority of people. Users who notice, that something might be wrong, test their forwarding service with a non-spf-protected address. Of course this test will pass, and so those users will likely think, well, there must have been an error occurring at the missed message's sender's side/point. Has anybody here experience about/from any mail service provider helpdesk explaining this issue correctly? However, this is my personal explanation of why there is such a small number of votes (now: 80) only, and which is why I don't believe that a "native" built in SPF feature will be released within Plesk in the mid-term future.

My personal recent server management helpdesk experience: I was told that PostSRSd cannot be installed on my Plesk12.5/Ubuntu14.04/Postfix server, since 1) Odin disadvised its use (referring to a user's statement in https://pleskautomation.uservoice.com/forums/216577-ppa-improvements/suggestions/7921188-enable-srs-feature-in-postfix-mailserver-nodes-under-PPA) and 2) because of general warranty and update concerns. Users should therefore avoid using the forwarding service and rather use, if available, a mailbox collector service on the forward-target-system [i.e. likely revealing smtp credentials to third party for comfort reasons].

we need it for Redhat Enterprise Linux with Plesk 12.0.18, please!

we need this to - CentOS 6/7 with Plesk 12.0.18 - thanks

It is available but only with external mail servers and only on Windows.

As a user of Plesk I have more and more e-mails that don't reach destination because of this - more and more domains are adding SPF.

thanks it realy works as i need it
