Speaking of 'not playing well with MS' I had a problem with that eariler this year on a Linux machine I support that was updated. I could send mail anywhere EXCEPT to machines running Miscrosoft exchange. I kept getting a name not being able to resovle [or similar] in the bounced mail from the MS machines. I contacted the HW/SW provider who has a lot of clients on our mail machines [not the problem machine] and asked him to check the logs at their machine, which also bounced messages. Of course as I've seen with many MS systems "We don't have logs - they take up too much space" After checking and rechecing it turns out the machine name got added with a trailing dot in the sendmail.cf when it was set up with SuSE's interface. I just toss this out in case someone sees something similar - coonections to all except MS machines working. Bill -- Bill Vermillion - bv @ wjv . com
