cannot send mail from local machine

harsshal · 02-15-2009, 06:24 PM

When i try to send mail using 'mail' command to mail.server1.com,I cannot send them. However I can send mails to user@gmail.com.
Is that because sender is user@192.168.0.XX?
How can I change this sender?

You might take a look at your access list database and make sure that you have allowed mail from that subnet. It looks like you are running Fedora so it will be in /etc/mail look for a file called access. Follow the protocol as displayed in the file and then you will have to rebuild the database: "makemap hash access<access" (without the quotation marks of course). The try sending a message.

I ran 2 commnads

Code:

#mail -s hi xyz@gmail.com
bye
ctrl + D

#mail -s hi xyz@nyu.edu
bye
ctrl + D

xyz@gmail.com gets the mail but xyz@nyu.edu doesn't.

sorry but I did not find the file with protocol

Code:

[root@mymachine ~]# cat /etc/mail/access
# Check the /usr/share/doc/sendmail/README.cf file for a description
# of the format of this file. (search for access_db in that file)
# The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc
# package.
#
# by default we allow relaying from localhost...
Connect:localhost.localdomain		RELAY
Connect:localhost			RELAY
Connect:127.0.0.1			RELAY

[root@mymachine ~]# file /usr/share/doc/sendmail/README.cf
/usr/share/doc/sendmail/README.cf: ERROR: cannot open `/usr/share/doc/sendmail/README.cf' (No such file or directory)

Should I just go ahead and rebuild the database using "makemap hash access<access"?

I think before we go too far, it might be good to get a look at your actual mail log. Should be in /var/log/maillog. Try posting the parts of that when you send a mail to gmail and to the other domain that you were trying. Have you tried sending to a yahoo address? Or any other valid domain? Try those things and then repost with the text of your mail log. That might help narrow the search for a solution. Thanks!

OK.solved it.
I think the problem was 'nyu.edu' did not like the mails from local machine,the machine which did not set reply to address correct.These mails had reply to address as user@192.168.0.xx.

Thus, I changed 'from' field in mail using -f option and it worked.

Thanks a lot guys.Specially ScooterB.
