You know so much more than me, and I appreciate all you time and efforts.

jeelliso · 06-15-2006, 02:37 PM

Unfortunantly, I don't have much more information for you right now. I will ask around and see if I can't some up with something. Keep an eye on this thread and I will let you know if I find out something. If you figure it out on your own, let me know becuase I'm kind of curious now.

Good Luck,
~Justin

Rridler, I have found something interesting. I just tried doing a telnet to your server on port 25 and it did not get through. I would imagine that has something to do with the issue.

Code:

telnet> o
(to) ridler.homedns.org 25
Trying 216.196.163.43...
telnet: connect to address 216.196.163.43: Connection refused
telnet: Unable to connect to remote host: Connection refused
telnet>

The thing is though, that traceroute you did looks like it should be getting through.

Good call pdeman2, I just assumed that since HE could telnet to his machine that I could also. I can telnet to his port 80, but not to port 25. rridler, run

Code:

ps -aux | grep sendmail

to see if sendmail is actually running correctly. If it is, then it should look something like this:

Code:

[jeelliso@dada ~]$ ps -aux | grep sendmail
root     32353  0.0  0.0  8084 3116 ?        Ss   14:27   0:00 sendmail: accepting connections
smmsp    32361  0.0  0.0  7136 2588 ?        Ss   14:27   0:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
jeelliso 32642  0.0  0.0  4872  636 pts/0    S+   15:49   0:00 grep sendmail

Maybe we can fix this after all; I'm not giving up yet.

Any more suggestions?

unSpawn · 06-28-2006, 10:58 AM

Can you see if the messages you're trying to send are queued with the "mailq" command? If you do "echo "/mx pomeroy.com"|/usr/sbin/sendmail -bt" it should return the three mailserver addresses for the domain. Can you telnet to any and all of them on port 25?

rridler · 06-28-2006, 12:02 PM

echo "/mx pomeroy.com"|/usr/sbin/sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> getmxrr(pomeroy.com) returns 3 value(s):
mail.pomeroy.com.
mail1.pomeroy.com.
mail2.pomeroy.com.

Your ISP may be blocking or filtering port 25. You may need to set up a smart host in sendmail.
Check out this article
Setting up Smart Hosts with sendmail

rridler · 07-13-2006, 01:23 PM

Thanks for all the help, but it does seem to be that my ISP does block port 25 and they don't allow use of port 25 unless I have a business class account with them. RATS!!!!!!!

So much for my own email account. RATS, RATS, RATS!!!!!!!!

Unless you have an other way to work around it...............................
