also i tried unistallating and reinstalling qmail toaster. that also didn't work.

I also tried changin hostname.

ok now i noticed that after reinstalling mails are in queue list. how to fix that. i can see all send and received mails there.

also pelase tell me how do i send mails to their respective email ids?

[tinu]

cat /etc/resolv.conf
; generated by /sbin/dhclient-script
search local ovh.net
nameserver 2xx.1xx.3x.9x

[MRatWork]

Add 'nameserver 8.8.8.8' and 'nameserver 8.8.4.4' in resolv.conf.

[tinu]

i did and rebooted my server server didn't reboot.

booted in rescue mode provided by ovh and restored resolv.conf again. server still not start.

i will inform later what happens . my guess is i have to reinstall server.

[MRatWork]

I don't know ovh panel but possible change nameserver via their panel.

[tinu]

dont know what is issue. i accessed my vps in rescue mode and wont able to find problem.

i am reinstalling vps and after reinstall first thing i am going to do is put google nameserver ip in resolv.conf

this resolv.conf previously stopped my internal network and now since last four installations mailserver is giving problems.

i will chattr+i resolv.conf

am i doing right?

[tinu]

I reinstalled server and mail server is running fine now but i am sure in a few days it will stop working again. what should i do?? 

[tinu]

it started now again. mails are neither sending nor receiving.
mails are going to queue again.
i just restarted mail server.
thats what caused problem each time i restarted mailserver. its fresh installation.

now i am pretty sure if i restart server it wont boot. please take a look.

please help me mustafa i am giving you server ssh access.

[MRatWork]

Instead using 'vpsxxxxx.ovh.net'. change hostname to 'mail.oneofyourdomain.com' in /etc/sysconfig/network' and then run 'hostname -v mail.oneofyourdomain.com; sh /script/fixmail-all; sh /script/restart-mail'.

Also make sure permit/open all mail ports in ovh panel (if exists).

[MRatWork]

If still not work, give me an access to Kloxo-MR panel.

No PM accept.

[tinu]

Did you mean you didn't received PM?

If that's what you mean can u plz check i have sent a pm again.

Email already send and received but still problem because no enable 'spf' and 'dmarc' (under ''mail auth').

I think your dns setting for cloudflare still incomplete (like missing spf dan dmarc).

Test your domain via intodns.com and mxtoolbox.com.
