Hi, I've a bit problem.
here is my acl from sender veryfication:
check_sender:
accept hosts = :
require message = Can't verify sender
verify = sender/callout=10s,connect=2s,maxwait=30s,defer_ok
accept
And when a get spam mail dnslookup hang for some mails....
Here is a debug output from such a mail:
10085 SMTP<< MAIL FROM:<samqazhl@h> SIZE=4542
10085 spool directory space = 3622048K inodes = 641162 check_space = 15360K

10085 log directory space = 3622048K inodes = 641162 check_space = 2048K
inodes = 20

When i try use
# time host zytechnologies.com
I got:

zytechnologies.com A record not found, try again
real 0m20.000s

but exim4 hungs forever...
My lookuphost router (which is the first) looks like:
lookuphost:
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
And the transport is:
remote_smtp:
driver = smtp
For other spam, where DNS server respons it looks like this:
10208 SMTP<< MAIL FROM:<stephen@???> SIZE=31395
10208 spool directory space = 3622020K inodes = 641162 check_space = 15360K

<cut>
and the mail is rejected due to spam score...
Can anybody tells me, what i should do with this?
How can I cat off the dnsloookup if it doesn't work...
Because every time when I get mail like the first one, i have the exim which
hungs in backgroud,
and after that a get DOS because max_connection from localhost reached out..
Sorry for my english...
