Hi: Thanks, Ed, and Steve. You all did help a lot in my problem. Sorry, that my question was a bit comfusing at the first time. And very sorry too that the question led to a bit of controversy between some of you. Steve: I did as what you told me to; but I noticed that, the version of Sendmail shipped with Shrike does not support the file relay-domains anymore or it is being replaced by another name (I don't know). Could you please clarify a bit more with this? Best regards, Vidol -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
