mail not sending

rpadilla · 07-28-2005, 12:03 AM

We have a redhat 9 with php and mysql, problem now is mail wont send anymore, mail is sent through php mail function, we just relay our email to another mail server, below is the log in the var/logs/maillog

Code:
Jul 28 08:37:23 localhost sendmail[7558]: j6S43H9O006736: to=<name@domainname.com>, ctladdr=<name_demo@localhost.localdomain> (506/506), delay=11:34:06, xdelay=00:00:00, mailer=esmtp, pri=1110359, relay=mailserv.domainname.com, dsn=4.0.0, stat=Deferred: Connection timed out with mailserv.domain.com.

by the way using another box, even windows with php I can send and receive email using the same configuration.

Also not sure if this is the problem

I did try to telnet, mailserv.domain.com @ port 25 and I got a connection timeout from that box.

Maybe some configuration on sendmail is messed up?

Thanks

Timeout errors usually indicate that mail isn't running.. whatever it is your using, either sendmail, postfix, qmail.. etc.. ??

I did check the server, I think its sendmail. but not too sure, i'm still new to linux.

It sounds like a firewall problem.

would it help if I change to another mail server,

I have another mail server which i can telnet @ port 25 and is ok,
but how can I change my relay server?(ok i think a little google)

but would help if someone can give some inputs.

thanks

Hi,

Now I did try to use another relay server, using telnet I was able to connect to the new mail server and was able to send and receive the email,

Now I change my sendmail.mc and uncomment this one and add my new relay mail server
define(`SMART_HOST',`newmailserver.domainname.com')

and m4 it.

now I got a new error, still i wasnt able to receive the mail

Code:

Jul 28 **:33:54 localhost sendmail[3876]: STARTTLS=client, 
relay=newmailserver.domainname.com., version=TLSv1/SSLv3, verify=FAIL, 
cipher=DHE-RSA-AES256-SHA, bits=256/256

Jul 28 **:33:54 localhost sendmail[3876]: j6T4Xs1k003873:

ctladdr=<user_name@localhost.localdomain> (505/505), delay=00:00:00, 
xdelay=00:00:00, mailer=relay, pri=30337, 
relay=newmailserver.domainname.com. [*ip address*], dsn=5.6.0, 
stat=Data format error

Jul 28 **:33:54 localhost sendmail[3876]: j6T4Xs1k003873: 
j6T4Xs1k003876: DSN: Data format error

maybe still need some config to do?

thanks
