Email takes a lot of time to deliver

[Racuncai]

Sending an email to a third party email service like gmail takes a lot of time, i don't see any error on direct admin panel, i need some help please.

SPF, DKIM, DMARC - configured? IP/domain not blacklisted?
Server load ok? if you don't have IPv6 - you can disable it in exim conf.

 

[Racuncai]

Yes, SPF, DKIM and DMARC are configured, There's no ip/domain blacklisted, the server load is above 10, i don´t have ipv6 i haven´t disabled it.

 

[Zhenyapan]

LA 10 - means 10 cores loaded to 100%, how many cores your server have?

 

[Racuncai]

4 cores

 

[Zhenyapan]

so you must make load less then 4 for fast emailing etc.

 

[Racuncai]

How can i check why the load is so high?

 

[Zhenyapan]

from ssh - "top" or "atop" then most loaded processes logs.

 

[Racuncai]

I don't see the problem using htop, 1.65 out of 7GB and cpu it's under 35% usage php-fpm has the highest cpu usage.

 

[Zhenyapan]

can you send screenshot of top, at least header and first 15 processess?
you can see them in DA process monitor too

 

[Racuncai]

This is an screenshot of the processes

 

[Zhenyapan]

but there LA not 10, just 0,7 - so all must work fast!
how long email sends? maybe you have slow dns-resolvers? if your hosting provider has own - try to use them. or maybe your spam checker test outgoing emails too hard?

 

[Racuncai]

That's what i notice, everything should be blazing fast, I'm checking the dns entries and we have some issues there i'm working on it, thanks for the answers.

You could use mail-tester.com just to test if your rdns SPF, DKIM, DMARC are working correctly. I have always found it handy.
