Well I'm not aware of any libs, but here is project which seems support it and opensource. http://doubango.org/ On 28/08/12 02:08, Rick van Rein wrote:

Hello,

The ENUM services for E2U+sms:mailto, E2U+mms:mailto and E2U+ems:mailto refer to ITU standards TS 23.140 and TS 26.140 -- elaborate descriptions of how emails should be exchanged to relay SMS / MMS /EMS content.

Is anyone on this list aware of an open source implementation, preferrably one whose interoperability has been shown?

Thanks, -Rick
