Hi all,
I'm having an issue where an errant email address to a bogus domain (
gmail.ca) does not reject the message, but gives a temporary rejection
message instead.
main.log.04.gz:2010-06-17 11:49:13 H=??.??.??.?? (??.??.??)
[xxx.xx.x.xx]:27645 I=[xx.xx.x.xxx]:25 F=<fake_address@???>
temporarily rejected RCPT anotherfakeaddress@???: host lookup did not
complete
the domain gmail.ca doesn't exist, and it seems to be the only domain which
causes this issue.
My acl_check_rcpt verify statments are as follows:
acl_check_rcpt:
accept hosts = :
drop
message = Username and Password required for mail submission
condition = ${if ={$interface_port}{SUBMIT_PORT} {1} {0} }
! authenticated = *
deny message = Restricted characters in address
domains = +local_domains
local_parts = ^[.] : ^.*[@%!/|]
deny message = Restricted characters in address
domains = !+local_domains
local_parts = ^[./|] : ^.*[@%!] : ^.*/\\.\\./
deny message = Refused: You have reached your sending limit of \
$sender_rate_limit per $sender_rate_period
log_message = BLOCKED - Rate limit reached
authenticated = *
! senders = +rate_exempt
ratelimit = 1000 / 24h / per_rcpt / leaky / $authenticated_id
warn log_message = Rate for $authenticated_id : $sender_rate /
$sender_rate_period
authenticated = *
condition = ${if >={${sg{$sender_rate}{[.].*}{}}} {10}}
accept local_parts = postmaster : root : mailman : mailer-daemon
domains = +local_domains
accept hosts = +accept_servers
endpass
message = Unknown user or bad forwarding address for
$local_part@$domain
verify = recipient
require verify = sender
accept hosts = +relay_from_hosts
domains = +local_domains
endpass
message = Unknown user or bad forwarding address for
$local_part@$domain
verify = recipient
accept hosts = +relay_from_hosts
accept authenticated = *
domains = +local_domains
endpass
message = Unknown user or bad forwarding address for
$local_part@$domain
verify = recipient
accept authenticated = *
deny message = Relay not permitted - Authentication required
When I perform a command line smtp session through telnet I get the
following error
HELO ???.uleth.ca
250 ???.uleth.ca Hello ???.uleth.ca [142.66.6.147]
MAIL from:me@??? <from%3Ame@???>
250 OK
RCPT to:reneenicole.rg@??? <to%3Areneenicole.rg@???>
451 Temporary local problem - please try later
quit
Is this some kind of DNS issue? Is there a convenient way to reject all
gmail.ca addresses. I'd rather not do that as it seems like a horrible way
of dealing with what seems like a more systemic issue.
Thanks
