Agreed.  They are heavily rate limited to deter spam so they're not great
for mailing lists.

If you actually want to send SMS, you need to pay for it through one
of the many SMS API services.  It costs on the order of 0.7c/message
to US numbers which seems pretty cheap to me, but I suppose that
depends how valuable you think your lists are.

Trying to integrate directly with mailman would be a nightmare, but
you could easily set up a kludge where people subscribed separately to
the SMS forwarder, subscribe a special local forwarder address to the
mailman list, and then tie a script to that address that takes the
contents of the messages and passes it to the SMS API.  (Stripping out
all the extra cruft, of course.)

Google for nagios sms notifications. As I recall something was doable 
with a basic dialler program and a modem back when, now you can get a 
GSM modem and send actual sms'es.


Off the top of my head you'd put this behind a script-mailbox and 
subscribe it to your list and Robert's your parent's sibling.

Hi,


Hi Dave,

I've been using mailman to send routine announcements for a long time 
and more and more what people want is a text message. I've been able 
to discover gateways for individual carriers so that I can send to 
@..com and the subscriber gets a text, so 
phone notification which is quick and handy. This has been well received.


I've been looking at the list of carriers getting longer and have looked 
into email to sms services but what I've seen has been commercial and 
too expensive.

I don't think I've seen a collaborative or open source email to SMS 
project.  I suspect this is because of the technical nature of 
gatewaying and / or the cost associated with doing so, be it 
infrastructure or per message.


The only free services that I've seen have been operated by the cellular 
networks for their customers.


The other commercial services have all had cell phones (or other similar 
devices that interface with the cellular network like a phone) and end 
up sending lots of texts.


I don't see how to overcome either of these limitations.  Maybe there is 
a way.


I feel like sending text message is beyond the scope of what a mailing 
list manager should do.  If some of the subscribed addresses happen to 
be email address that are subsequently gatewayed, so be it.


If you really want to look into something to send SMS (or MMS) messages 
in bulk, I'd look at something in parallel with Mailman.  Let Mailman do 
what it's good at, email, and use something else for SMS (MMS).
