Narrative:

We were cleared to push off of our gate onto the line in the alley. The ground crew pushed us too deep and parked us beyond the line; facing south with the line sitting under my left wing; 15 to 20 feet away. As we completed our engine start we called for taxi and were switched to metering. Before I had even released my brakes a crj entered the alley on the [parallel] line. Knowing that my right wingtip was way across the centerline; I sat with brakes parked; waiting for the crj to stop short which would allow me to transition to the left onto the line. The crj never did stop and continued on to his gate. My first officer signaled with his hands for the crj to stop; but it never did.the crj cleared us by mere feet. From our vantage our wingtips may have overlapped as he passed. Compounding the error; the crj made a ninety degree turn to his left while he was abeam us; turning into his gate. The turn caused his tail; which was taller than his wingtip; to swing by our wingtip; narrowly avoiding us a second time. We switched the radio back to ramp as the crj passed us and notified the ramp of the near collision.our push crew pushed us too deep which set the incident in motion. We recognized the problem after we were too deep; but purposely left the brakes set until I knew we could safely correct back to our centerline. The crj seeing us way to deep and encroaching on his side decided to taxi anyways. The push crew should have dropped us on the centerline. Once we were too deep they could have pulled us forward back onto the line. I have no idea why the crj chose to risk a collision; knowing that the safety margin of the surveyed separation had been compromised. When in doubt set the brakes and call for a tug; and wing walkers.
