Last Friday our Exchange server stopped sending mail at 9.30am. We\ncould still receive mail.\n\nLooking at the Qs the outgoing messages were sitting in a Q called\n"Messages with an undeliverable destination" Nothing I could do\nwould send them. When I was able to get them into the send Q they\nwould drop back to the undeliverable Q.\n\nThis Q apparently cleared around 4.00PM Saturday afternoon. when\nthere was no one here. THis has happened several times before but\nclears it's self after about 6 hours usually in the same day.\n\nHas any one else had this problem on Xtra and how have you gotten\naround it??\n\nI assume by the fact that this suddenly happened and it suddenly\ncleared that the problem was at Xtra but try to get them to admit that\nfact..
