Sendmail... help..... >_<

:newbie: First of all, as I am not good in English, please forgive my poor words...

I installed sendmail and using no-ip.com for my machine domain.

I can send mail using my server "sammysam.no-ip.com" but it can't receive any mail even I closed the firewall and edit the following lines in sendmail.mc

dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

to produce the new sendmail.cf.

I can use openwebmail to send mail! But no mail can be received for any users.....

I received the following message:

Code:

I am using a router but already open the port 25

What's wrong..... help!!!! I used several days for it..... I am getting crazy now~~~

Thank you very much for your kindly help!!:confused:

Well, if you want to use your mail server to send mail from any host other than the box sendmail is running on, then remove that line from your MC:
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
That means it will only listen on 127.0.0.1 (localhost).

I am gathering that no mail is being received for the no-ip.com domain on your box, correct? If so, make sure no-ip.com exists in:
/etc/mail/local-host-names

This tells that it should deliver all mail for that domain to a local user.

Yes, my problem is only on receiving mail for the no-ip.com domain. I have already added those names in the local-host-names file like

Code:

localhost

sammysam.no-ip.com

no-ip.com

sammysam

Is it right? Any punctuation needed? Thanks for your help!! :D

That should be sufficient. try sending an email to a user on your box at the no-ip.com domain and check /var/log/maillog to see the error messages, if any.

Thank you very much for your kindly help... But I still can't solve it... I check the maillog but nothing special. A lot of "TO" mail (send out) log and a few "FROM" (receive) log. All "FROM" log are local mail.... I still can't send mail to sammysam@sammysam.no-ip.com.... but I can use this account to send out mail..... >_< SENDMAIL is too hard to configure.....

Well, do you have an MX set up for this subdomain?

may be u are using same machine as name sever and mail server in that case make alias for the host and change the mx and ns with the alias this shuld fix your problem of not receiving the mails but not completely ...u cud find the messages sent in the /var/spool/mqueue with strange names as q349HW090284 being delievered...thats where i am stuck with ...i think the problem is in your dns config files

I don't know how to set name server... Therefore, I really don't know what's wrong... :confused:

Ok, is no-ip.com your real domain or just something you made up for security reasons?

:) no-ip.com is a dynamic ip domain name service from www.no-ip.com. I apply a domain name "sammysam.no-ip.com" from it and install the update client which will update by ip to www.no-ip.com to map my domain name. I don't have any DNS (I even don't know how to set it)....

Thank you very much!! You are very helpful and kind~~~:p

Ok, then you need to find out if that service will forward mail for that domain.

Oh I see... Then, can I use the ip for the mail server? just like can I send mail to sammysam@61.15.79.41?

thanks~~

You need to point your domain name to your mail server. 'MX' is the keyword here.

There is a place on the no-ip.com web page under your domain name where you enter your server info. IE MX record. I don't now how to set up sendmail yet but I have seen the place you enter he mx record on no-ip.com. Good luck. I am about to tackle sendmail myself.
