DKIM Key in TXT field gets cut.

This is most likely caused by the character limit on the text entry box so you should be fine with a 1024 bit encryption but to exceed the current character limit would require the variable type changing which could have wider reaching ramifications so would need checking to make sure that the new variable type is accepted by all of the other actions that hinge on the content of these fields. Might be worth manually entering the data for now
