I was discussing this with a Cox Tier 2 support person for over an hour with no resolution. He said that he had never heard of this error??? Cox we need this fixed. Since people are using various e-mail clients (I am using Thunderbird), it is a Cox issue. The Thunderbird sending message progress bar indicates that the message was anywhere from from 98% to 100% complete, but it never finishes. It shows the additional "Internal queueing" error. Once I clear that error, the progress bar clears. This is the same issue that occurred last fall and took a good week to resolve.
EDIT-1: I called support again and things seemed to be working at that point. Tried again later sending out a small e-mail blast of six e-mails. It initially refused to send the first one, but sent the rest. After the third try of the first one, it finally sent it. So we still are having issues.
