When performing some testing on sendmail handling of addresses
the following error message occurs:
"buildaddr: no user"
Sendmail has been invoked as /usr/lib/sendmail -v /dev/null {address}
This problem only occurs when the address matches one particular rewrite
rule in S0. The address is something like grants@mhs.donald and matches
a rule:
R$*<@$=C>$* $#bmailer$@$2:$1
The F macro defines a class of hosts in the file /etc/bhosts, which contains
the name 'mhs' (from address above). When the rules are tested in address
test mode (sendmail -bt) the address resolves to the correct mailer as shown
by the output below:
ADDRESS TEST MODE
Enter <ruleset> <address>
0 grants@mhs.donald
rewrite: ruleset 3 input: "grants" "@" "mhs" "." "donald"
rewrite: ruleset 3 returns: "grants" "<" "@" "mhs" "." "donald" ">"
rewrite: ruleset 0 input: "grants" "<" "@" "mhs" "." "donald" ">"
rewrite: ruleset 3 input: "grants" "@" "mhs" "." "donald"
rewrite: ruleset 3 returns: "grants" "<" "@" "mhs" "." "donald" ">"
rewrite: ruleset 0 returns: "^V" "btos" "^W" "mhs" "^X" "grants"
Can anyone offer any suggestions as to why the error 'buildaddr: no user'
occurs ?
Thanks In Advance

The error message is correct. When you are resolving to a mailer, you have to provide the following: a mailer - marked by $# an optional hostname - marked by $@ a username - marked by $: Looking at your rule's RHS (wih optional spaces added for readability) shows: $# bmailer $@ $2:$1 which breaks out into: bmailer the mailer $2:$1 the hostname? But where is the username? Perhaps you meant for the RHS to read: $# bmailer $@ $2 $: $1 Now you know why I use the optional spaces in virtually every rewriting rule in my cf files - it makes problems much easier to find. Using the optional spaces also make lines containing $@, $:, and $> easier to read. Remember the rules: 1) the LHS, RHS and comments must be seperated by at least one tab character 2) there may be embedded spaces in the LHS, RHS, and comments 3) tabs or spaces begin continuation lines 4) blank lines and lines beginning with a pound sign ("#") are comments IMHO, alot of people might be less intimidated by sendmail.cf files if they contained more spaces.
