By drilling holes, the envelopes are able to get past some US Postal codes for regulations. If the envelope is totally closed, it fits into these codes and violates the law. i.e. Should be managed and/or regulated by the US Postal Service. The other common answers also make sense. The holes drilled in the envelope allows you to see if the envelope contains anything, without having to untie the string to look inside.

Interoffice envelopes have holes in them to indicate if there is any contents enclosed. When the envelope is sealed and holes are punched out, it signals that there are documents inside. This helps offices easily see at a glance if something needs to be delivered without having to open the envelope.
