sendmail, change domain name

**efrenba** · 03-20-2006, 06:41 PM

Hi,

My sendmail shows me:

============ SYSTEM IDENTITY (after readcf) ============
(short domain name) $w = mailsrv
(canonical domain name) $j = mailsrv.subdomain.domain.com
(subdomain name) $m = subdomain.domain.com
(node name) $k = mailsrv.subdomain.domain.com

How do i change those parameters, because my domain name is "subdomain.domain.com" not "mailsrv.subdomain.domain.com", "mailsrv" is the box's name?

Thanks...

Hi,

First of all, thanks you...

I've another doubt, I've sendmail running locally, I access it by telnet to 25 port but from a remote pc I cann't do it.

What params of config do I must to touch to allow remote access to sendmail?

Thanks...

I"m not sure what you mean by remote access but ....

If you mean you need POP or IMAP, you can't do that with Sendmail. Sendmail is MTA (Mail Transport Agent). Check here for more info.

If you mean that you can't receive mail from external, follow this link and it will show you how to enable it.

HTH ...

Hi,

>I"m not sure what you mean by remote access but ....

On my box I typed telnet 127.0.0.1 25 and I received answer from sendmail but from a remote pc I typed telnet 192.168.90.5 25 and I couldn't connect to it.

For that reason I wonder what config's params do I must touch so that sendmail is able to accept a message from a remote PC?

I've the outlook express prefectly configured. Please take a look to Outlook's error:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: '192.168.90.5', Server: '192.168.90.5', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

Thanks again....

You need to configure relay of messages or you need to configure pop access. Like I said before, Sendmail IS NOT a POP (Post Office Protocol) server. Sendmail is simply a MTA (Mail Transport Agent). Like I've said in above post, if you need POP sever, follow the link to find out how to set up POP sever.

Think of it this way. You send your package via your local Postal Annex. They dont' actually deliver your mail. They will send it with your preferred carrier, FedEx, UPS or PostOffice. Then those carriers will do the delivery to your destination. Think of Sendmail as those delivery services such as UPS.
