Hi,

On my server some of my clients websites are loading with the www. before it and then if u try it without it its not.

and vice versa on some of them.

ANyone had this issue before and how do i resolve this. Iv tried to check in dns administration and couldnt find anything.

Cheers,
Kevin.
 
Im also thinking this is resulting in every email i sent out to antyhing outwith my server its sending back.

What should the format of this file be /etc/resolv.conf

I have
nameserver 127.0.0.1
nameserver 94.23.26.204
nameserver 213.186.33.99
search ovh.net
 
Whether the client can see his site with or without the www is not related to resolv.conf

Likely you made dns changes recently and things are still trying to work out. Likely it will just take time.

The other thing is you could have some real dns issues that can be fixed. However we cannot help you since you did not provide any examples for us to research.
 
Hi,

Nice little site that is to use. Any ideas on how I can sort this?

Cheers,
kevin
 
Everything looks fine from my end.
Another cause could have been .htaccess file, but usually it is DNS.
 
The only issue I have now is the sending of mail on the server wont work. Im querying as to why.

Wont send anywhere and everything is in the mail queue adminstrator.

THing is tho in that queue i dont know alot of the emails on it that are randomly wanting to send from my server.

it's a very handy site, yes it's showing your dns as fine now.

regarding the mail, i'm not an expert you could try "retry" some of the mail that is stuck in the mail queue administration and then have a look at your exim log to see what is wrong.

tail /var/log/exim/mainlog

someone can maybve advise if this is wroing or perhaps a better suggestion.
 
its ok this is now sorted. was a problem within resolv.conf.

Only thing is none of my mail will send out and niether will any of my clients. Made sure all the mail ports are unblocked.

Still cant get anything

Keeps coming back as unroutable address.

I have tried everything. Even if i was to send to my own email address it still wont work. Only works internally. Any way of checking the outgoing mail settings as in what IP its set to incase its 127.0.0.1
 
Here is an example below

2009-03-05 02:07:18 1Lf23S-0002PM-Ag <= [email protected] H=localhost (ingoo.1click-hosting.com) [127.0.0.1] P=smtp S=1169 [email protected] T="More strength, length, and pleasure with less efforts." from <[email protected]> for [email protected]
2009-03-05 02:07:18 1Lf23S-0002PM-Ag ** [email protected] F=<[email protected]>: all relevant MX records point to non-existent hosts or (invalidly) to IP addresses
2009-03-05 02:07:18 1Lf23S-0002PO-Co <= <> R=1Lf23S-0002PM-Ag U=mail P=local S=2087 T="Mail delivery failed: returning message to sender" from <> for [email protected]
2009-03-05 02:07:18 1Lf23S-0002PO-Co ** [email protected] F=<>: Unrouteable address
2009-03-05 02:07:18 1Lf23S-0002PO-Co Frozen (delivery error message)
2009-03-05 02:07:18 1Lf23S-0002PM-Ag Completed

Just to let you know those email addresses dont exist on my system but i have 400 odd pages of frozen mail on my queue. Only about 5 emails on those 400 odd pages belong to me and my clients. Just these other emails are weird comin from somewer.
 
ingoo.1click-hosting.com appears to be your hostname. Have you checked for any compromised mail/contact forms?

Essentially from the cut/paste you did, email is being sent out and hitting a non-working email address ([email protected]). So it comes back with a delivery fail, but it comes back to [email protected] which is unrouteable (hostname), thus creating a crapload of frozen emails. That's just a quick guess from your snippet.
 
Just checked all accounts and everything seems to be fine. Going to restart server to see if that mailqueue wil clear.
 
Nope looks like the mail queue will just build and build just now. COuldnt find any things that were sending out mail. Even checked ps aux so see if there was anything in ther. Only thing i find strange in ther is
Ther is processes loads of them from dovecot and the command is imap-login

also got 2 on root that say spamd child

another process from mail .. command is /usr/sbin/exim -bd -q15m -oP /var/run/exim.pid

last one from mail is /usr/sbin/exim -q


Any ideas?
 
resolv

resolv.conf check it on ur own server. has the main ip at the dc and then ur nameserver ip. stuff like that. I had it muddled around. Just my mail wont send is my issue. Anyone help?
