Hello,

I'm having some QMail problems, it doesn't matter what, but to fix it, I need to change my server's hostname from "localhost.localdomain" to a fully qualified hostname. How do I do this with RedHat Linux 7.0 ? I tried

hostname -v blazebox.com

and when I do that, it indeed says it is updated, and when I execute "hostname", it indeed gives "blazebox.com" , but when I restart Apache, PHP still says its hostname is "localhost.localdomain" , and when I do a reboot, and then execute hostname, it says "localhost.localdomain" again...

Anyone knows an answer to this?

Thanks in advance.

can you tell me a little more with teh problem you're experiencing?
Are you getting serious lag and timeouts when trying to connect to pop3 and smtp?

and thirdly are you running the tcpserver or inetd with qmail?

regards,

Simon

Make sure the hostname is set in /etc/hosts

Try checking your httpd.conf file, did you change it in there in the ServerName field. For qmail go into
/var/qmail/control look in the "me" file what does it say there?

You shouldn't have to specify the ServerName in your httpd.conf file; it should be able to figure it out automatically. That directive was put in there for OS's with severely borked networking.

If memory serves me correctly check in /etc/sysconfig/network

Si-WHN, I think mailservers are rejecting mail sent over his server because his hostname is what filters call forged.

Yeah, the mail send through PHP was rejected because PHP tought my hostname was localhost.localdomain .... solution: change the hostname to a "real" hostname, and it's fixed...

I don't have any form of lag or something... I just kept getting the following message in /var/log/maillog :

Mar 2 09:25:14 localhost qmail: 983546714.909828 delivery 19666: failure: Connected_to_212.72.39.208_but_sender_was_rejected.

Now everything works smoothly :)

And how did you manage to change the hostname successfully?

1) hostname -v blazebox.com
2) edit /etc/hosts
3) edit /etc/HOSTNAME (RedHat 6.x only I believe)
4) edit /qmaildir/control/me

I only did the first 2 steps.... just to be sure, I did a "shutdown -r now" ... I don't know if it was necessary, but it never hurts....

Anybody know how to do this with Plesk?

"me" is correct.

This is what i did in ssh:
I edited the /etc/hosts and added the ff line:
209.217.0.0 srvr4.domain.com srvr4

and: /etc/sysconfig/network:
NETWORKING=yesFORWARD_IPV4=falseHOSTNAME=srvr4.domain.comDOMAINNAME=domain.comGATEWAY=209.217.1.1GATEWAYDEV=eth0

and rebooted my system =)

i still havent solve the qmail lag prob, but it seems to me that it is dns related cuz im trying to network 3 different servers with 1 domain :P doh!

later...

That's not for Plesk is it?

Plesk is not an issue here.... I used Plesk, and it worked.... Plesk doesn't use the hostname, PHP does.... restart Apache, PHP will be restarted, and you got your new hostname lighten up in PHP :)

Nope, none of that exsists...

You have ICQ or MSN messenger? That talks a little better, and probably I can help you....

lmergen@hotmail.com or 55677353 (ICQ is preferred)

I've got MR.

Here's my problem:

sendmail uses the correct host.domain.com
BUT
sendmail.plesk uses localhost.localdomain
me and the host name is correct.

So I've no idea where it's pulling this info from.

Plesk doesn't use sendmail, it uses QMail

That was my problem.... I had to change PHP's sendmail to QMail

umm... sendmail/sendmail.plesk is for scripts and qmail is for SMTP... check it out...

Mines on plesk too :) after changing the servers hostname i wasnt able to use qmail , course i forgot to enable smtp :P ... its working now.

thing is that sendmail stopped working and i need it to work :(... i'll keep you posted once i have a solution to it (if i ever have one :()and pop3 still lags.

I am using /usr/local/plesk/qmail/bin/qmail-inject as my mailer program for PHP, and it works better than perfect :)

But what exactly is your problem?

Look at my post "plesk reconfigurator" maybe that will help you more.

we had a similar problem with timeouts on a previous server running qmail and vpopmail.
It was due to reverse lookups occuring everytime someone connected either via smtp or pop3.
From memory the parameter you need to add to your tcpserver config line (perhaps in /etc/rc.d/rc.local?)
is
tcpserver -Hl your.host.name otherparams follow here
That will force tcpserver to use the hostname specified and stop it doing a reverse dns lookup on the hostname that you're running qmail on.

Hope this helps.

Simon
