sending mail from the command line
I am trying this from a Linux machine which is connected to the internet via PPPoE ( for the test, no firewall): mail -s "test" danshi...@gmail.com < /dev/null and also this mail -s "test" danshi...@gmail.com enter add some text enter ctrl-d I don't get any mail in danshi...@gmail.com. What is wrong here ? what should I do in order to send successfully an e-mail from the command line with "mail" ?

Re: sending mail from the command line
Hi Dan, Check the configuration of the email server on the machine on which you are working. It might be not configured or it might be misconfigured. In this case, it will be happy to accept your email sent using "mail" but wont know what to do with it and wont even be able to tell you. Start by looking at /var/log/maillog (for Sendmail installations) or /var/log/mail.log (commonly used in Postfix installations).

Re: sending mail from the command line
Thanks! I use sendmail. I see this in /var/log/maillog: localhost sendmail[4900]: p4AEvbvW004900: to=danshi...@gmail.com, ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=30225, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (p4AEvcRG004901 Message accepted for delivery) it says stat=Sent, yet I do not get that mail. I suppose this is some sendmail conf problem.

Re: sending mail from the command line
Hi Dan, Indeed it looks as though your mail did in fact go out to gmail. There is a chance that gmail silently dropped your mail in its spam filter. You could use tcpdump (as in wireshark) on outgoing traffic to destination port 25 to examine the traffic between your machine and the receiving machine. Alternately you could send to another mail server that has less opaque filtering.

Re: sending mail from the command line
according to the logs - the mail was not delivered to an external machine. check your sendmail's mail queue (using 'mailq') to see if the message is still there. it could also be that the mail was delivered to some local mailbox, instead of to google. the fact that it claims that the relay is 'localhost' implies that your sendmail is not configured properly. you should configure the relay to be the mail server of your ISP. --guy On Tue, 2011-05-10 at 15:02 +0300, Dan Shimshoni wrote: > Thanks! > I use sendmail. > I see this in /var/log/maillog: > > localhost sendmail[4900]: p4AEvbvW004900: to=danshi...@gmail.com, > ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:00, mailer=relay, > pri=30225, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent > (p4AEvcRG004901 Message accepted for delivery) > > it says stat=Sent, yet I do not get that mail. > I suppose this is some sendmail conf problem. > Did anyone have tips on sendmail configuration? there seems too much > about it on the web for simple configuration (for me it is enough only > to send mail, don't need to receive with sendmail) > > > On Tue, May 10, 2011 at 2:29 PM, Jonathan Ben Avraham wrote: > > Hi Dan, > > Check the configuration of the email server on the machine on which you are > > working.

To this advice I would add, most email providers will not accept mail from dynamic IPs. You probably got blacklisted the moment you tried it unless you have static IP and reverse DNS. Otherwise you will have to configure sendmail to use your ISP's mail server a relayhost as Guy said, and then send mail out from there. If that is all you want to do then some mini sendmail replacement is going to be much easier to live with than full-blown sendmail. Look for ssmtp, msmtp, etc. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

I'm sure I could if I was an Oracle marketing rep, but I really don't care. I use Linux, Solaris, and 3 different BSD and they all have their good and bad points. YMMV. I didn't bother to look at your link but if you don't like what I wrote, think of the value of comparing whatever OS you are talking about running on *Itanium* to running it on x86. That's not exactly a sound basis for comparison :rolleyes: I was suggesting to the OP it might be good to try a different OS on *his* hardware if he has a nice box and isn't happy with the performance. I don't see the crime in that and sorry some of you found it so offensive. Maybe you should just buy him an Itanium farm if you feel so strongly about it ;-) Have a nice day. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Re: MS buys Skype - will it support Linux
Unless they radically changed, their main goal is to force people to use their OS and Office suit, so the support for any other platform would be weak at best. What reliable alternative can one use for VOIP and phone in Linux? Including land line and cellular calls for low cost. I remember Ekiga, but do not think it ever got too far off the ground, and last time I tried google voice was not that great under linux either.
