Once again an extremely helpful article. Thank you very much! What I have seen of mailboxer seems to assume that the sender of the message is picking the recipient out of a list of already-registered users. Does mailboxer include an option where, instead of picking from a list, the sender can just enter a name or address, and then the message is sent to that name or address? This would work like, say, gmail–as a sender, you do not need to see a dropdown of all gmail users (which would be a lot!) before sending. Rather, you just type in the address you know, the system then locates the recipient, and the message is sent, or you get an error if the address you entered is incorrect. Does mailboxer allow for something like this? If not, no worries, I will just have to make some custom methods on top of mailboxer I suppose, but just wanted to check. Thanks!
