I've noticed a small problem with what I believe is the localdelivery agent, or perhaps a ruleset in my sendmail. I've set up a 'virtual mailmapping' setup in sendmail, using a hash database, so if somebody uses, for example 'webmaster@thecoffeehouse.com' it is supposed to forward to 'krioni@ma.ultranet.com'. According to sendmail in -bt mode, and doing an EXPN, sendmail is responding correctly, but when the message actually gets to krioni@ma.ultranet.com, it is addressed to 'krioni@ma.ultranet.com@netrail.net' (netrail.net is our local domain). I'm trying to track down what is causing this problem, and solve it. Anybody have any ideas? Let me know thanks. I've included a copy of our sendmail.cf if you wanted to take a look at it. ------------------------------------------------------------------------- Jonathan A.
