Mail Error: Unable to relay for ....

[telemorgan]

I wrote a script on our Solaris server ( ver. 8 ) to send an email to my cell phone when the disk space gets above a certain %. However I am getting this error when the script trys to send mail outside the company to my phone. Internal mail is fine. Anyone know what settings need to be tweaked in order to clear this problem. Thanks

BTW: I edited the # with "x".

Check /var/log/syslog to ensure the e-mail is actually leaving the sun system, but it looks like either the destination e-mail address has a typo (hence not being delivered) or your company firewall is "bouncing" the e-mail. Can you send e-mail to your cell phone from outside your company (eg from a hotmail account, etc) ?

I hope that helps.

Here is the entry from the /var/log/syslog. It does look like its gets to the exchange server (10.10.28.68). Also I can send the email to my cell phone from my desk computer using the same address.

Thanks,

Try changing your script to use a 'from' email address option that is legitmate for dns, like your own email address.

 

[blainepruitt]

By default sendmail uses MX records to forward mail. For example, if your /etc/resolv.conf files has a nameserver entry other than localhost, then you will need to check the MX records on the nameserver in question. Chances are, if you are running exchange it is forwarding the mail to that point and it is being rejected as a forwarder. You can get around this by having the exchange server allow mail from your IP address, or updating your DNS accordingly.

thanks everyone. blaineprutt, that is exactly what is going on. I just got off the phone with the email admin here. Seems they have shut off the relaying feature (anti-spam effort). Only mailbox accounts can send and recieve mail. So looks like im not going to be able to use this or any internal mail server.

i would like to try to configure my solairs server to route mail via this external ip 167.206.112.6

anyone know how i can do this?
also can this be done while still using my local (internal) nameservers.

Thanks again
