I've been trying together with my host to get this working, but somehow when trying to add, it doesn't give any error, but it doesn't add the record either. Would there be any special format DirectAdmin uses?
I've tried just about any way to enter it, omitting any of the numbers, leaving out dots, but it doesn't matter it just doesn't give an error and doesn't put the record in the server. At least it doesn't display it in the list.
I'm having the same issue so I'm guessing this has not been fixed in the latest build. I've put in a support e-mail but would love to know if anyone else was able to get this working (maybe I'm missing something).
Pardon my ignorance. What purpose do SRV records serve ? How does this affect a domain if the user changes it (which one just did, his domain doesn't resolve any longer)
