Re: Email to text - vtext.com blacklisting ip

Just a heads up to everyone with these suggestions, Mike is complaining the
thought of using a paid service for a "critical" function to be a waste of
bandwidth.  He will then block your email address.

Just thought I'd save everyone's time from trying to help him.  He is only
concerned about fixing the free service and not a solution to the problem.

This subject pops up every 6 months and it's a problem that can be solved
100 ways. One way we did it at Team Cymru was install a foxbox sms gateway
in our datacenter. It was a pain to get working, (mainly due to some
miscommunication with the Italian support team), but one we got past a few
problems it works flawlessly for all alerts. If alerts are unack'd for a
specific amount of time, escalation alerts go out via email-to-sms AND SMS
to a broader group to ensure someone gets the message.

Thanks,
Scott

We use Zang.io and are very happy. Be careful when using long codes (10
digit numbers) as if you send too many messages out in a day (500+) the
larger carriers such as Verizon will start blocking you. As Jeff
mentioned
if your monitoring tool is onsite and the internet goes down then it's
worthless. In our case it's in another DC so if everything goes down we
still get alerts. You can also try twilio and telnyx.

Same boat...  We are sending messages to PHONENUMBER () vtext com and
getting
bouncebacks or lost items.  I assume its because some limits are now
being
put
into place.  We are a Verizon subscriber so I am paying, it is not a
free
service.  But .... I am totally up for paid services if you can
recommend
some
that will reliably get us texts to our verizon phones.

I agree. Pay Pager duty or a SMS gateway with a SLA. Relying on  the
free
service
for anything critical is asking for trouble.

If it's critical I'd suggest a service than can depended on...

Hi,


    I have a server that monitors my network and issues text
messages
if
there are events of note that require human intervention. There is
some
process filtering that ensures it also is not able to issue more
than 1
alert maximum per 5 minutes, to ensure it doesn't flood pagers with
messages all screaming the sky is falling when things are not going
well.
Recently however, this server is no longer able to deliver messages
to
vtext.com - it gets nothing but 554 errors:


telnet 69.78.67.53 25
Trying 69.78.67.53...
Connected to 69.78.67.53.
Escape character is '^]'.
554 txslspamp10.vtext.com
Connection closed by foreign host.

Granted on some days during challenging times it can send 30 or 40
messages before we get to it and get it squelched / silenced, but
it's
otherwise reasonably well behaved IMHO and I don't think we are any
heavy
volume sender. So I am trying to figure out why it's blacklisted
then
and
am rolling snake eyes.  If anyone who is an admin for verizon or
who
has
any insight to share I'd certainly appreciate it. Email to text is
a
critical function we depend on.


Thank you.
