I think you might need to set 'rcpt-to' in smtpd.conf on the lmtpd line, otherwise the 'envelope' RCPT TO is your unix username, instead of the mail's envelope recipient. That said, you'll likely run into problems with extensions: many services reject + in the username part of a mail address. Petr -- id' Ash = Ash; id' Dust = Dust; id' _ = undefined
