New YH Error coming through pipe

by NeoEclipse 3 replies
So past week or so I'm starting to see a new error come across some of my sending ips. I've looked all over the net and yh's pages and cant find anything. The url it gives in the error links me to the general page where all the common smtp errors are found but no GL01! Anyone else seeing this strange new error please let me know!

Error has been seen when sending 500-50,000 mails.
