I don't think it is permanent only because he can't send messages. I assume this also happens when accounts are suspended for a limited period of time. At any rate other people who posted here did usually get a message when their accounts got suspended, so it is weird your father didn't get a message or a warning about the suspension. Are you sure your father's account didn't get hacked or something and that that might be reason why he can't log in?
As already suggested, contact eBay CS. We are not eBay staff here. If your father needs to log in in order to contact eBay staff, contact them yourself and explain the situation. If this happened while he was discussing postage, it is indeed possible the bots misunderstood something, although if this is the case I didn't realize accounts now get suspended immediately without eBay looking into it.
I remember that many years ago I had asked for a "PayPal combined invoice", and my message could not be sent because eBay thought I was asking for a transaction outside eBay. I reworded my message and it went through and then nothing happened - no suspension or anything, so I assumed they looked at the message and realized I was not asking for a transaction outside eBay.
I think it is unlikely they would suspend an account without looking at what happened. Bots are unreliable, and they know themselves because somewhere they say "sometimes we make mistakes", or something like that, like when people exchange contact details to arrange for pickup and then get blocked.
