Thank you very much! That seems to have made the plugin work correctly.
I'm not sure if the etiquette on this forum is to start a new thread for a new topic, but I've immediately hit another roadblock that may be a bit of a bigger issue. Some details were mentioned previously, so I'll continue here unless told otherwise:
As mentioned in the prior post, the mail server situation here is... unique. We effectively have two domains, and when I ping the mail server's IP address, I receive three different hostnames. I have tried every combination of hostname, domain (there are two), protocol and port (albeit, only the typical ports, all of which are open on both the osTicket server and the mail server). The errors I get are always timeout errors... yet I can ping the mail server from the osTicket sever with hardly any latency. I'm using the Oauth2 plugin, as mentioned previously. Any thoughts or ideas would be greatly, greatly appreciated.
