Oh, I’m sorry, did you need me to interpret that error message for you?

Dear Computer User,

When sending an error message to Tech Support, it’s generally helpful to say something about the message you are forwarding. We are not mind readers. Something like “I was doing X and clicked Y and this error message appeared” goes a long way to diagnosing the problem. While we’re at it, if the error message clearly says what the problem is, and it’s not something we can fix for you, but rather you need to fix for yourself, why waste our, and your, time?
To wit: forwarding us an email bounce message (and ONLY the bounce message!), when the bounce says:

The mail system

: host mail1.company.com[IP.AD.DR.ESS]
said: 550 5.1.1
: Recipient address
rejected: User unknown in virtual mailbox table (in reply to RCPT TO
command)

Says exactly what it means: User unknown. Forwarding this message to tech support of the sending mail server (without even saying why you’re sending it to them) is like dialing a phone number, getting a “number has been disconnected or is no longer in service” message, recording it, then dialing 411 and just playing the recording back to them. If you’re expecting the operator at the phone company to just figure out what you REALLY meant is “Why is my friend not answering the phone?” is rather silly. Expecting them to give you an answer more informative than “that number is out of service” is only marginally less silly.

Regards,

Every Technical Support Representative on the planet
