Do you have an RSS feed? And also will it be cool if I added in your feed to a blog of mine? I have a website that pulls content via RSS feeds via a several websites and I'd like to include yours, most folks do not mind considering I link back and everything but I like to get authorization first. Anyway let me know if you can, thanks. excellent stuff. Do you have an RSS feed? And also will it be cool if I added in your feed to a blog of mine?

MARKETING-CALLS@NO-MEDIA-OR-RHINOMARKETING-CALLSCONTROLALT.DELETENO-MEDIA-OR-RHINOMARKETING-CALLSCONTROLALTDELETE.CO.ZA even faster ;) the problem lies with the LocalPart and its length. Not with the domain. I believe the LocalPart can be broken in parts+domain and if the part evaluate fine, so will the whole and performance of the evaluation will increase. Not sure what the criteria would be for breaking the LocalPart in chunks. NO-MEDIA-OR-RHINOMARKETING-CALLS@CONTROLALTDELETE.CO.ZA could be split in NO-MEDIA-OR-RHINO@CONTROLALTDELETE.CO.ZA and MARKETING-CALLS@CONTROLALTDELETE.CO.ZA if both evaluate fine than the whole is fine. I guess where to put the split is not trivial with the more exotic LocalParts. MARKETING-CALLS@NO-MEDIA-OR-RHINOMARKETING-CALLSCONTROLALTDELETE.CO.ZA

evaluates fine.

MARKETING-CALLS@NO-MEDIA-OR-RHINOMARKETING-CALLSCONTROLALT.DELETENO-MEDIA-OR-RHINOMARKETING-CALLSCONTROLALTDELETE.CO.ZA

even faster ;)
