Hi, I have OTRS set up to receive Hyperic HQ email alerts. These work fine, but when I fix something in Hyperic, it sends out a new alert message with the same subject, suffixed with the word "fixed". The problem I have is that, because the subject line is different, OTRS raises a new ticket for what are really just follow-ups. What I would like to do is have OTRS rewrite the subject line to remove the word "fixed", thereby preventing it from creating a new ticket. I tried this in the Postmaster Filter section, but it won't let me select "Subject" in the "Set" section. I know the manual suggests that you can use Kernel::System::PostMaster::Filter::Match to write your own filter rules, but I'm not sure what the supported "Set" key/values are - if they're the same as provided by the UI, then I'll still have the same problem. Can someone suggest a solution? Regards, Richard Cross.
