    Hi,

    I've been using ispconfig for many years, thx for this robust tool!

    I host several domains on it.
    Today I need for 1 one my domain, to use an external smtp server. (i need it for letsignit, but I also could need it to use an external antispam gateway for sended mail)

    I cannot find how to do that.

    A bit more information :
    let say I have mydomaine1.com and mydomaine2.com configured on my server. both have mailboxes and can send email.
    I need all the mail sended by all the mailbox on mydomaine1.com to go to an external smtp server, in my case smtp.letsignit.com
    and all the mail sended by my users on mydomain2.com stay the same.

    any idea how to do that?

    thx.

    DNS change for mydomain1.com
    A record value mail with IP that external server
    then MX record change from mydomain1.com to mail.mydomain1.com
