"mail" command not working
 

I am trying to run a mail command from my Linux box and it does not seem to send any emails..

# mail -s Test xxxx@yahoo.com

There are no entried regarding any email attempt from teh box in /var/log messages...

What am I missing?

sendmail process is running ...

you need to send something, e.g. the empty file. Try,

Tried, no luck....

Infact my ealier attempt..I enter and then enter a message body..and then CTRL D to send message..

No luck either way...

You can check /var/spool/clientmqueue for the mail and read /var/log/maillog for any problems with sendmail.

But furthur it says timeouts..
sendmail[26973]: m8OK1rer026971: to=<xxxxx@yahoo.com>, ctladdr=<xxxx> (0/0), delay=00:38:01, xdelay=00:20:01, mailer=esmtp, pri=60342, relay=c.mx.mail.yahoo.com. [xxxxx], dsn=4.0.0, stat=Deferred: Connection timed out with c.mx.mail.yahoo.com.

Does my server need to have a valid email address to be able to send email out?

Any ideas?
 

Following up..any ideas anyone?

Thx,

Am I not asking the question right or is this group really cold!!!

No, we're just tired.

Probably. It depends on the kind of validation that's done on the receiving end.
But the error message you got indicates a connection problem. If the problem were
due to an invalid address, you'd get a rejection, instead.

You can try to see if you can connect to the yahoo server via telnet:
Are you able to connect to any other mail servers?

If not, then it's possible that your ISP is blocking outgoing port 25.
If yes, then some filtering (possibly based on IP address) is happening.

Those are some ideas.

It could very well be that you are being blocked by the ISP as they might not want you to run your own mail server. It happened to me. I eventually switched providers and everything was dandy.

you need to send your body

Blocking Mail!!!
 

OK, that makes sense, its comcast, I will call them and find out.

Telnet to yahoo mail server times out too

telnet 216.39.53.3 25
Trying 216.39.53.3...
telnet: connect to address 216.39.53.3: Connection timed out

Comcast said "use port 587 for sending mails out....

Do they block based on Dest Port or Source Port - not sure he didnt know...

Is there a way to change sendmail/smtp to use port 587?

Will that work?

You can solve this problem by relaying mail through your ISP's mail server.
With Sendmail, just set SMART_HOST to your ISP's outgoing server. You can Google for the proper way to do that.

Already looked..here is how to do it..
http://www.linuxha.com/other/sendmail/

But I get this error after doing all configs..
Plus I dont get this part?
Now edit the /etc/mail/genericsdomain file and add the entries you want changed, like this:

cookie!cookie!asterisk ncherry@linuxha.com

Now compile it into a db file:

# cd /etc/mail
# makemap -r hash genericstable.db < genericstable

Should I use genericstable or genericsdomain??? I dont have genericstable file and running above command complains about it....

Fixed by moving to Postfix
 

Was able to get it all to work thru gmail instead of comcast and postfix sendmail
