VMPRO not delivering all messages to email

[foosy]

I am seeing a strange issue whereby some messages get delivered by email and some do not.
When I check the SMTP logs I see that certain messages end with a failure as such:

[pre]09/03/2019 18:40:26.089 - Took 210949ms to send a chunk of text data 131072 bytes long

And some messages end without a failure as such:

Is anyone familiar with this error and can help with why this would be intermittent?

Hello,

What SMTP server is it ?
Connection seems very slow.
Network problem ?

 

[foosy]

Good point - I did not realize until you pointed out.
However, if this were the case, why would the shorter (21 sec) message fail and the longer one (35 sec) succeed?
There is nothing that changed in the SMTP server and this has been working for years and started acting up about a week ago.
Is there any way to check if the issue is with the sender or the receiver without changing the SMTP server?

 

[sizbut]

You still need to be a bit more free with the information if we're to be able to provide any help. I'd be looking for any patterns in the destinations addresses and size of emails.

There have been issues with commas and other non-alpha characters in addresses.

Some (most) email servers have limits on the size of attachments.

Stuck in a never ending cycle of file copying.

 

[janni78]

For the one that worked it took ~36 seconds to send 100228 bytes which in itself is a very long time.
The one that failed it took ~211 seconds to send 131072 bytes.

This is by no means normal and after 211 seconds I would guess the mail server just gets bored and drops it.

Thanks for the correction. Yes, it is definitely abnormal, I couldn't even believe it when I saw it.
The email addresses are all local. A same user could receive a message once, and not another time. The recording time is limited to 2 minutes so the generated WAV files all fall within the size that is OK to send. There is definitely a problem with the transmission time, which could be network related.

 

[canthony2]

Iv seen this issue before. Something on the SMTP server is queuing the message but is not sending (obviously). I believe its more server related rather network. Have you tried resetting your SMTP service? If that does not work try using a SMTP relay

 

[Beantown55]

I am having the same issue which just started on a server that has been working for years. Was there any resolve with this thread. Did anyone find out what the issue was. Thank you.

create a test email using some free service, like gmail or what have you, set up SMTP to use this and test again.

The strange thing is it works sometimes and then when you leave the next VM it doesn't work. Wait a bit and it will work again.

I created a Gmail account and tried it. Nothing. I get
22/07/2019 13:20:14.745 - Attempting to connect to host smtp.gmail.com on port 587, local bound address is (null)
22/07/2019 13:21:14.930 - CSMTPConnection::Connect: Could not connect to the SMTP server smtp.gmail.com on port 587. 10060 [0x274c] (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) calling connect from CMailSocket::Connect
22/07/2019 13:21:14.983 - CSMTPConnection:isconnect: Already disconnected from SMTP server, doing nothing.


When using AppRiver it works here or there. When it doesn't work I get this error:

Any Ideas!!!!!!!

 

[CarGoSki]

appriver shut down the free relays starting last spring.

 

[Beantown55]

Then why would it work sometime but when I tried Gmail I got nothing happening. Any ideas!!!

 

[TouchToneTommy]

I know for a fact that appriver relaying to gmail will fail every time

 

[Beantown55]

You must have misunderstood my lengthy email. It works when I put it through AppRiver here and there. Has been using that forever with no issues. When I remove all the AppRiver settings and use Gmail I get the error. So AppRiver works once and a while and Gmail doesn't work. Two different settings with two different providers. I think it maybe something on the network. Suggestions!!!!Thank you.
