was on phone, SMPP is short message peer to peer protocol for exchanging sms messages between peer entities. v3.4 the most used standard allows for a single connection (bind) that can send and receive messages). Our current implementation is with the Sun Messaging Server, which doesn't support full 3.4 so it only does one-way, which would be email-to-sms.
we don't want to use sendmail to accomplish this, so was wondering if exim supports the smpp v3.4 protocol for two-way smpp bind.
I tried searching through the documentation through the exim site but it fails to bring any results for this or anything else.
