    I should put the content of the 'DNS record' field form the mail server to a new DNS TXT record in the DNS server?
    You see, 'DNS record' field on the mail server has 452 characters and DNS TXT field on DNS server can only contain 255 characters - so I can't just copy/paste.

    Also, if I reconfigure my servers to multiserver setup, will I loose any data?

    The shown record is the full entry for your dns.
    Create a TXT-Record. Hostname: default._domainkey.domain.com. and Text: v=DKIM1; g=*; k=rsa; p=....
    You can also othe another key-strength

    Could you, please, be more specific?
    I should create new TXT record and in the 'hostmane' filed i should put 'default._domainkey.MYDOMAIN.COM.' and in 'text' field i should put everything after the 'TXT' from the 'DNS-Record' field in the 'DomainKeys Identified Mail (DKIM)' section?

    Yes. Or change your setup to a multiserver-setup with one interface. ;)

    Again, when adding 'DNS TXT Record', the field 'Text' can't contain more than 255 characters.
    And everything after 'TXT' in from the 'DNS-Record' field in the 'DomainKeys Identified Mail (DKIM)' section has 408 characters.
    I've already asked you 'Also, if I reconfigure my servers to multiserver setup, will I loose any data?', but there was no answer.

    In this case install the dkim-patch on your dns-server, too. This extends the allowd length for txt-records.
    You can convert your setup into a multiserver-setup. You have to merge the data into on server and switch the other servers to slaves.

    In my setup i have 5 DNS servers, but I only set DNS records on first DNS server, remaining 4 is all set to mirror of first DNS server.

    @ressel
    All of your 5 servers are DNS only servers?

    Also, one other thing:
    If I install the patch on my mail server, and domain is managed by GoDaddy, how to add DKIM record to GoDaddy?

    Here you can se how I build my server setup:

    On my DNS "slave" servers I have used following setup in ISPConfig.

    When I create a domain in DNS I only select DNS1 as my dns server, it will then automatic be replicated to all server that is setup as mirror (all of 5 of them).
    And to make it work, I have setup my DNS template to always use all 5 dns servers, so it will look like:

    This s great, thank you.
    One question: why would you need 5 DNS servers?
    Are they going down?

    @ressel
    How much RAM do you have on those that are DNS only?
    I'm thinking of setting up some DNS-only servers and I was thinking how much is enough.
    @florian030
    Still no answer?

    256MB should be enough for a dns only node as it runs only bind plus mysql plus the ispconfig server cronjob (you can disable innodb support so that it uses less ram).

    @till
    So, I should follow Perfect Server tutorial (eg for Debian 8), and after disable innodb support and use only 'DNS' tab in ISPconfig?
