Emails sent *from residential comcast subscribers* to any '@voicenet.com' address have been disappearing in the Comcast network since Sunday, Feb 31. There are no bounces or errors of any kind. Mail sent directly to other domains with the same MX record and even to individual machines within the MX record themselves work fine, it is only when the envelope recipient states /^.*@voicenet\.com$/ does the mail simply disappear (i.e. mail sent to "someuser@voicenet.com" disappears while mail sent to "someuser@mail##.voicenet.com" goes through fine as well as "someuser@voicenet.net"). My company as well as our customers and Comcast customers have together made many, many phone calls and sent many emails and we cannot get ahold of anyone with any semblance of a clue and nobody seeems to have the ability to put us in contact with anyone in your systems and/or network admins (level 1-3 techs, managers and even "case resolution specialists"). Can someone please contact me off-list in regards to this situation? Has anyone else had similar problems? Thanks. -- Tim Wesemann Voicenet Systems Administration
