It looks like I'm running version 63.
Wait that was the version I was running. Switched up to 68 thinking that something might have been fixed or headers had changed. Haven't had a page since I switched. Have to see what changed. VZW support says it has cut down the number of people that can be addressed per message.

I only have 6 VZW subscribers on my group, so I'm under the 10 users limit.
I may upgrade to the newest version too. I like to live by the motto if it isn't broken, don't fix it. ;)

Ditto. 63 did everything I need and was stable. Once it was working I didn't touch it. Another thing I have considered doing is enabling 2 factor auth and then doing an app specific password for the software. Maybe there is a header that says "account is secured" that Verizon is picking up on.

Andy. If you would be willing I would help you develop a batching workaround to this. Maybe if we could send in bursts it would let us through.

Yeah, if we can confirm what will get around this issue with Verizon, I'll code in a workaround. I've gotten quite a few reports of this in the last couple days. I could use some help in figuring how to get around it. Batching into groups of 9 recipients at a time is certainly possible, but if what KLH is saying is true that may not do the trick.

Can you guys try sending to multiple recipients (including more than 10) straight from gmail and see what bounces back?

I'm not running a setup with enough Verizon users to test this, so I'll be needing some help. If a few people can consistently reproduce the problem and a workaround, I'll fire those folks some test versions of the program to try out prior to release.

Just sent a message out to all of my guys after the last reminder page at 6pm. Just took the list of folks it tried to send to, composed and it seems that all went through. This was a text only message. Here is what I have done.

1) Move to v68 from v63. Left all settings the same.
2) Set BCC = 0 so the system sends as a group not hidden.
3) Observed "Failure to Deliver" on all vzwpix.com emails containing page from 6pm. My StraightTalk that rides on Verizon came through but uses the mypixmessages.com address. Verizon network not issue, Email gateway seems to be.
4) Copied all addresses from the message with MP3 email, filtered to just vzwpix.com and composed email addressed using To field. Send message asking for responses. Have received multiple messages saying "Not receiving the audio pages".
5) Did the same as step 4 with the guys on AMR. Same response, not received.

Unsure what the issue is. Appears we CAN send to more than 10 (one was 9 folks the other was 15, all text messages received from the appearance. Maybe batching wont help. May try a few more things. Dont dive in just yet Andy.

To make sure I understand correctly - you sent an email to all of your vzwpix.com users using your normal email client, and they received it? Did that email contain an audio attachment? Would the IP address that you manually sent from be the same IP that TTD would have been sending from (IP from your ISP, not the IP on the LAN)?

My Vzw and sprint receive direct email with audio attachments by bypassing ttd and just sending it directly from the email client.

Actually I didn't really try that. Here are the other operational parameters from the test:
1) Sent from Gmail web interface, no external email client used.
2) Sent from another IP address and not from our firehall. Logged into web service from my home computer. We are using the same ISP and are in the same town.
3) No attachment of any kind was used. Pure text only.

Our Assistant Chief is a web guy and has a URL for our department registered. He setup an email that is outside of gmail I assume but I have not switched to that. That may be my next challenge. If you would like I can probably get a number of the folks to let me do a test from the computer using Thunderbird or the like.

Ok...I'm trying to determine if emails are being blocked based on:

- IP address
- Number of users
- TTD email header
- Presence of attachment

Any testing that can help us narrow in on root cause would be great.

Here is the message from Google about the Verizon rejection (slightly sanitized).
Code:
Delivery to the following recipient failed permanently:

     [email]402-------@vzwpix.com[/email]

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain vzwpix.com by smtpin01-mms.vzw.a.cloudfilter.net. [52.0.44.141].

The error that the other server returned was:
550 5.1.0 <deshler...@gmail.com> sender rejected

IP based filtering could be a thing. TTD header could be another but would need to confirm by testing another client. That Received: field might be tattling on our low security.

I think number of recipients may have something to do with it. Tried doing an attachment to a guy last night and it went through but that again was from the web interface. I'll do some more digging and see what I hit.

Here is a discussion from another forum about this issue.
It appears you are limited to the number of messages your email is allowed to send per day. After that you are put on a spam list (for the day maybe?)

NotePage, Inc. :: View topic - Verizon has modified their SMTP gateway

Intersting. That has error 554 error but I am getting 550. Maybe someone flagged me as spam since they didn't tell me their email changed. I will look into that Enterprise system they mention.

I am suddenly getting blocked emailing my own phone @vzwpix.com through gmail. I think the problem is VZW is sending these messages through:

smtpin01-mms.vzw.a.cloudfilter.net

...and cloudfilter is blocking us for some unreasonable rule.

I think the best course of action is to get VZW subscribers to start calling in and complaining that they can't mail their own phones with an MMS attachment and that "cloud filter" is rejecting us until someone in VZW is willing to look into it.

Yeah I've tried contacting Verizon and they refuse to talk to me since I'm not a customer...

VZWPIX testing results

All tests were sending to three Verizon users:

Test 1 - gmail account using gmail web GUI to vtext addresses with no attachment - all 3 were good
Test 2 - gmail account using gmail web GUI to vzwpix addresses with mp3 attachment - 1 out of 3 were good (large audio file was stripped for two users)
Test 3 - gmail account using gmail web GUI to vzwpix addresses with amr attachment - 3 out of 3 were good (small audio file)
Test 4 - TTD TonesEditor Admin email from gmail account to vzwpix addresses with no attachment - all 3 sender rejected message bounce back from Verizon
Test 5 - twotonedetect.net using gmail web GUI to vzwpix addresses with amr attachment - 3 out of 3 were good
Test 6 - twotonedetect.net email account using TTD TonesEditor admin email to vzwpix addresses with amr attachment - 3 out of 3 were good
Test 7 - twotonedetect.net email account using gmail web GUI to vzwpix addresses with amr attachment - 3 out of 3 were good, received within 1 minute
Test 8 - twotonedetect.net email account using TTD admin email to vzwpix addresses with amr attachment - 3 out of 3 were good, received within 1 minute
Test 9 - twotonedetect.net email account using TTD admin email to vzwpix addresses with extra comma and amr attachment - 3 out of 3 were good, received within 1 minute
Test 10 - gmail account using Thunderbird email client to vzwpix addresses with amr attachment - all 3 sender rejected message bounce back from Verizon

Conclusions:
- Emails will bounce with far less than ten recipients per message
- Sending from gmail via the web interface seems to work ok
- Sending from gmail using a local email client (TTD, Thuderbird, etc.) appears to bounce
- Sending from a non-gmail (twotonedetect.net) account with TTD seems to work ok, at least for up to 3 Verizon users

Before I continue this conversation Andy I must give you major props for testing through all of that. That took dedication and I thank you for it. Testing is often underappreciated but this answers a fair bit.

The outcome, unfortunately, is less than ideal. Must be the fact that we are sending THROUGH gmail that they don't like. This leaves us with 4 choices.

1) Figure out a way to get around the block using some trickery or web scripting.
2) Work with Verizon to implement a solution. Enterprise messaging somehow?
3) Use alternate delivery methods. Upload files to a server then send a link to the sound that can be listened to.
4) Abandon sending MMS messages to Verizon users and hope that a plain text message alerts them to something. IF the vtext portal still works.

I have built a few tools that can upload the specified file (usually MP3) to a server then use Pushover to send out a link. You can easily click the link but that requires data for the device. Older, plain phone, users would be left out. I have also started looking into Twilio as they can send MMS. Problem is Twilio is 2cents per message per user. That adds up quickly.

Guess we press on looking for a solution or workaround. The most obvious is to switch from gmail to something else.

I didn't test it, but I've gotten some reports of vtext also causing issues and bouncing.

To get the audio attachment, data connectivity is required, even on older "non smartphones". So by switching to a different delivery method that uses data, the only users you're leaving out are those that don't have smartphones, which is an increasingly small number of users. Maybe the solution is to just send emails to those smartphone users on Verizon and have them set up an alert on the phone for when an email from that address is received?

I'd like to be able to provide an easy delivery method for TTD users that doesn't require them to set up a web server, etc. If anyone has ideas for how to do that, I'm open to ideas. I'd like to avoid requiring a specific service or infrastructure...email has enabled that to date, but it seems like it's getting harder and harder to send to MMS via free email services.

Hosted service opportunity? Sounds like a lot of work for you beyond editing tone files.

Unfortunately I can really only see 2 viable options at the moment: Figure out a way to get into Enterprise Messaging from Verizon or switch to a different email provider. Any clue if something other than Google/Gmail works (seems like urls hosted through google wont work)? Outlook.com, serversmtp.com, or any other good free providers that we could register through?
