sendmail 8.12.7

[HPP]

Hi,
I have upgraded the sendmail on HP-UX 11.00 to 8.12.7. Installation went well.
Configured sendmail for spam blocking using DNS based IP address spam list. It is working fine as for blocking spam emails and receiving other emails. But when i try to send mail from my outlook or eudora operation timed out waiting for response from SMTP server.

If i disable spam blocking using DNS based IP address spam list, it works fine.

Why is this happening??

Any help in this regard greatly appreciated.

Thanks

Forgot to add one more thing:
On outlook or eudora when I click send and receive i do see a proccess on mail server saying "startup with xxx.domain.com (This is my local domain). This happens for both the cases mentioned above.

Thanks

Hi,
I didn't understand all, but I think you should configure reverse lookup on your dns server , in order to give an answer with the IP of your outlook/Eudora client.
I.E. :
nslookup from your server you give an answer..

benoit,
Thanks for the reply. Yes i did nslookup and nslookup and i dont have problem with it.
When i click send on outlook I do see a process on sendmail server. When I do "ps -ef|grep sendmail" on sendmail server, i see a process "sendmail: startup with client clientpc", but the send fails and outlook gives the message as shown above. Do you know why it is happening??

Receving a mail works fine.


Thanks

An extract of /var/adm/syslog/mail.log would be usefull to understand the trouble.
Could you attach this extract with this error in order to see exactly what is the trouble.

benoit,
Sorry i cant send the mail.log as it contains our internal network node address. But i can tell you what gets logged in mail.log when i try to send mail from outlook. I see
Feb 12 08:09:13 mailserver sm-mta[3171]: h1CD7rUf003171: mypc.doamin.com [192.168.19.228] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

Thanks

From WHat I see, it seems to be linked with the client configuration (time out).
YOu can try from your workstation to telnet directly on port 25, and see if all is OK :
example :
$telnet 25
you should have :
222 ESMTPSendmail 8.11.6/8.11.6; Wed, 12 Feb 2003 16:00:52 GMT
then type :
$helo domain.com
answer :
250 hello pleased to meet you
$ mail from :ben@domain.com
250 2.1.0 ben@domain.com... Sender ok
$rcpt to:@domain.com
250 2.1.5 @domain.com... Recipient ok
$data
354 Enter mail, end with "." on a line by itself
THis is a text
.
250 2.0.0 h1CG3KS14239 Message accepted for delivery

If you have an error before the end, what is the message ??
If you don't have any error, check config on your client .

benoit,
Thanks for your reply.
Actually i recreated sendmail.cf again. Before creating i removed unwanted blacokhole lists and kept very few. Now the response from server is better, still working to make it faster.

Thanks again.
