SRS problem with SpamExperts Send Mails

[btk]

Hi,

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), deactivating the relay host in main.cf there isn't problem; but we opened a ticket with they, and they said that's a problem with plesk/postfix config, can suggested any idea?

Thanks.

SpamExperts does a SMTP callout to verify the validity of the sender address. Currently Plesk fails to accept emails to the SRS rewritten sender (whilst it should accept such messages and redirect it to the original sender address). Once Plesk resolved that issue, there should be no such issues.

Hi,

We find the solution here: https://support.plesk.com/hc/en-us/articles/115000063949 [PPM-5259]

Simply, add "-s" string on master.cf at line that begins with plesk_virtual unix

This appears to disable SRS, rather than solving the bug where the SRS rewritten sender fails to handle a redirect to the original sender.

Sorry, it's correct. I have left it solved because, at least temporarily, it allows the output of the mails without the need to eliminate the relay host of the file master.cf, which, in my case, caused problems with other domains of the same VPS.
