We're in a real pickle over here. Somebody faked our support email address and sent an email to an autoresponder that does not return the same subject title. So our cases have filled up with some 200 back and forth messages with no end in sight. The other company is perfectly clueless. They don't even understand what is going on. Is there any way using PostMasterPOP3.pl that we can block specific email addresses or domains so their mail is not imported into OTRS? Our system is running perfectly and I really don't want to switch to procmail or something else I don't fully understand. It appears that using procmail is a totally different type of setup so it's a bit much right now. Even if we had to do some hack to the code that receives the email and do it there.. that's acceptible to us, we just don't know where to do it. direct email replies along with the list are welcome and actually requested since we're currently down for the count until this can be resolved Thanks for any help guys charles.thompson@indysoft.com
