http://www.postfix.org/local.8.html Mailbox delivery can be delegated to alternative message transports specified in the master.cf file. The mailbox_transport_maps and mail- box_transport configuration parameters specify an optional message transport that is to be used for all local recipients, regardless of whether they are found in the UNIX passwd database. I checked the source code. src/local/mailbox.c:296: if (*var_mailbox_transport) { state.msg_attr.rcpt.offset = -1L; *statusp = deliver_pass(MAIL_CLASS_PRIVATE, var_mailbox_transport, state.request, &state.msg_attr.rcpt); return (YES); } /* * Skip delivery when this recipient does not exist. */ if ((errno = mypwnam_err(state.msg_attr.user, &mbox_pwd)) != 0) { msg_warn("error looking up passwd info for %s: %m", state.msg_attr.user); dsb_simple(state.msg_attr.why, "4.0.0", "user lookup error"); *statusp = defer_append(BOUNCE_FLAGS(state.request), BOUNCE_ATTR(state.msg_attr)); return (YES); } if (mbox_pwd == 0) return (NO); Execution must not reach the second 'if' because I have mailbox_transport. However I find "user lookup error" messages in the log. (And mail is not passed to mailbox_transport defined by main.cf.) So the message does not come from here but from src/local/dotforward.c:126: /* * Skip non-existing users. The mailbox delivery routine will catch the * error. */ if ((errno = mypwnam_err(state.msg_attr.user, &mypwd)) != 0) { msg_warn("error looking up passwd info for %s: %m", state.msg_attr.user); dsb_simple(state.msg_attr.why, "4.0.0", "user lookup error"); *statusp = defer_append(BOUNCE_FLAGS(state.request), BOUNCE_ATTR(state.msg_attr)); return (YES); } if (mypwd == 0) return (NO); Also "local -v" shows the same: Feb 16 15:10:24 NEWMTA postfix/local[6860]: deliver_alias: hash:/etc/aliases-arc hive(0,lock|no_regsub|no_proxy|no_unauth|fold_fix): +trash not found Feb 16 15:10:24 NEWMTA postfix/local[6860]: deliver_dotforward[7]: local +trash recip +tr...@newmta.example.com exten deliver tr...@newmta.example.com exp_from tra sh Feb 16 15:10:24 NEWMTA postfix/local[6860]: warning: error looking up passwd info for +trash: No such file or directory [...] Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr status = 4.0.0 Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr diag_type = Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr diag_text = Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr mta_type = Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr mta_mname = Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr action = delayed Feb 16 15:10:24 NEWMTA postfix/local[6860]: send attr reason = user lookup error Feb 16 15:10:24 NEWMTA postfix/local[6860]: private/defer socket: wanted attribute: status (In this test I wanted to drop mail into "Trash" shared folder.) Now I try to figure out why the deliver_dotforward() code is executed instead of deliver_mailbox() ... Gabor
