I am receiving this error in my listserv.log file: 452 4.3.1 Insufficient system resources (UsedDiskSpace[C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Queue]) Most everything I find seems to point to the exchange server as the problem. However, is there any other possibility it is something in listserv? I have 35G free on the disk, and almost all the ram is free. ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1
