    So another TXT record like v=DKIM1; k=rsa; t=s; p=LONG_STRING_CONTAINING_PUBLIC_KEY_GOES_HERE

    Interesting - How would this work if I used both namecrane AND mxroute for outgoing emails for my domain (I don't.... yet) ?

    You have DKIM entries for each, using a different selector (from memory, mxroute always uses 'x', namecrane uses a random one so there's no overlap)

    Or see if it's possible to use the same certificate on both (not recommended). On Virtualmin, i have a option to specify the certificate being used to sign the outgoing mail if I dont want to use their auto-generated one.

    Never make the same mistake twice. There are so many new ones to make.
    It’s OK if you disagree with me. I can’t force you to be right.
