Hi, I want to know if there are any tools or scripts to check mail flow between two servers. What we do now is : to check the mail flow between abc.com - xyz.com , we send a mail to an invalid account at abc.com from xyz.com every 15 minutes. If the mail bounces back correctly, the flow is okay. The problem here is, a person need to check every fifteen minutes if the bounced mail as arrived. Is there any way to automate the above process? Thanks & Regards, -- Mejo
