configuring the MX field in ispConfig

Hi to all,
the mail and DNS aspect of things is still a bit confusing for me.
I have a domain with a registrar: kameleon.fr

The DNS servers are those of my registrar, and since I'm not a specialist, I think I'll leave it like that for now, for security.

So, I simply created a field of type A > ip_address_my_ispConfig

But I would still like to manage my email accounts.

At the moment, at the registrar, my e-mail account is configured like this:

Code:

@    IN SOA dns12.ovh.net. tech.ovh.net. (2020091700 86400 3600 3600000 86400)
                 IN NS     ns12.ovh.net.
                 IN NS     dns12.ovh.net.
                 IN MX     1 redirect.ovh.net.
                 IN TXT    "1|www.kameleon.fr"
www              IN TXT    "3|welcome"
www              IN TXT    "l|fr"

what I don't understand is;
do I just need to change the MX address or do I need to create a DNS zone for "kameleon.fr" in ispConfig for the domain that should receive the mails?

I can't find a clear explanation on the internet.

Thank you for your help.

 

hi @Th0m something like this ?

Code:

                 IN NS     dns12.ovh.net.
                 IN NS     ns12.ovh.net.
                 IN MX     5 redirect.ovh.net.
                 IN A      163.172.143.149
                 IN TXT    "1|www.kameleon.fr"
mails            IN MX     1 kameleon.fr.

I add one @ priority 1 "mails IN MX 1 kameleon.fr." and keep the registar one with priority 5 "IN MX 5 redirect.ovh.net."

 

Hi @Th0m , it drives me crazy with this DNS stuff, A fields, MX ...
is it better this way?

Code:

$TTL 86400
@    IN SOA dns12.ovh.net. tech.ovh.net. (2020091806 86400 3600 3600000 86400)
                 IN NS     ns12.ovh.net.
                 IN NS     dns12.ovh.net.
                 IN MX     1 kameleon.fr.
                 IN MX     5 redirect.ovh.net.
                 IN A      163.172.143.149
                 IN TXT    "1|www.kameleon.fr"

 

@Th0m You really want to kill me
Ok, I begin to create SPF, DKIM et DMARC @ my registar's panel, but when I activate my domain "kameleon.fr" in ispConfig I created DKIM. Do I need re-use it ? or recreate one in registar's Panel ? Thanks, sorry for my ignorance

 

hi @Th0m , I'm still lost in dns and mx jungle… Do you think it's ok now for my mx, little bit confused between mail… and mails whit s…

Code:

$TTL 86400
@    IN SOA dns12.ovh.net. tech.ovh.net. (2020091904 86400 3600 3600000 86400)
             IN NS     dns12.ovh.net.
             IN NS     ns12.ovh.net.
             IN MX     1 mails.kameleon.fr.
             IN MX     5 redirect.ovh.net.
             IN A      163.172.143.149
             IN TXT    "1|www.kameleon.fr"
             IN TXT    "v=1; a=rsa-sha256; c=relaxed/simple; d=kameleon.fr; h=  user-agent:message-id:subject:subject:from:from:date:date  :content-transfer-encoding:content-type:content-type  :mime-version; s=default; t=1600528607; x=1602343008; bh=T9revRd  3WumQMFXseASINmXH+K5"
         600 IN TXT    "v=spf1 a mx ptr ~all"

www          IN TXT    "3|welcome"
www          IN TXT    "l|fr"

 

Oops …

 

better ?

Code:

$TTL 86400
@    IN SOA dns12.ovh.net. tech.ovh.net. (2020091906 86400 3600 3600000 86400)
             IN NS     ns12.ovh.net.
             IN NS     dns12.ovh.net.
             IN MX     1 mails.kameleon.fr.
             IN MX     5 redirect.ovh.net.
             IN A      163.172.143.149
         600 IN TXT    "1|www.kameleon.fr"
         600 IN TXT    "v=spf1 a mx ptr ~all"
         600 IN TXT    "default._domainkey.kameleon.fr. 3600   TXT   v=DKIM1; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDKIFt176rW+/tmeS0wy6+uHgT/yrExC/NE7/Gxe9O985dubtC3vdkiylurusy/FGNT7fCo4dX9KFH9IaRaBaMXiIyQgG/cl/xHNLqXL0ZFr+8VnM3ann8DAJT78UDHjvBZypJHEmNuqB/Fclo8mK0Mi24+w2"

www          IN TXT    "3|welcome"
www          IN TXT    "l|fr"

 

I just realized that I have installed ispConfig with "srv-b.democrasite.com" by default. I don't think it's a problem, but I prefer to use this domain for mail management, I recreated everything under "democrasite.com" if I didn't make a mistake.

Code:

$TTL 86400
@    IN SOA dns200.anycast.me. tech.ovh.net. (2020091914 86400 3600 3600000 300)

             IN NS     dns200.anycast.me.
         600 IN MX     1 mails.democrasite.com.
             IN MX     5 redirect.ovh.net.
             IN A      163.172.143.149
             IN TXT    "default._domainkey.democrasite.com. 600   TXT   v=DKIM1; t=s; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAzmcV6/lmbB5QjazI/af5dY61OIAAoo/lzFqIHqrcm4o039bqQPTGB7S4qrRrDwtFRldj5ZQvVoBE3kJnlEt19cWZS7no2FvnfDq//S5NF6d3OIgo4soT3Y3EHwnKLmqESCc4GLRtBmEGd/B+gy"

hi @Th0m , thanks. But I still have an issue with rDNS and I don't find the way to fix it and to understand it. So i still have error with mails_checkers.
My installation is on a VPS instance @ scaleway ; seems like droplet's Digital ocean. I nommed this instance : srv-b.democrasite.com as my hostname in ispConfig, maybe the first mistake…

Anyway, if I follow intsructions to find the reverse adress ;

Code:

$ dig +noall +answer -x  163.172.143.149
149.143.172.163.in-addr.arpa. 60 IN    PTR    149-143-172-163.instances.scw.cloud.

I don't know where to enter this value.
