Out of Order Emails #bug


 

This has been going on for a little while, but it seems to be getting worse over time.

Emails are being delayed, sometimes by several hours. Often times they are delivered to some people quickly, and others slowly. Often I will get a reply to a thread before the original email ever hits my inbox.

This is happening to the @TosaSpokesmen group - I don't know if its unique to our group or if it happens to everyone.


 

Nick,


Emails are being delayed, sometimes by several hours. Often times they are delivered to some people quickly, and others slowly. Often I will get a reply to a thread before the original email ever hits my inbox.

This is most likely caused by some members' email service using as an anti-spam technique.

Another thing we've seen is some services throttling delivery from Groups.io, but as far as I know those have resulted in bounced messages rather than delayed ones.

This is happening to the @TosaSpokesmen group - I don't know if its unique to our group or if it happens to everyone.

I suspect it is unique to members using specific email services, and not to the group(s) they are in.

Not really a bug. Among others, cox.net, spectrum and roadrunner are known to delay/throttle mail delivery. If you can get a copy of the header of the delayed message, paste it into the analyzer at?.?This will tell you who's holding things up.?

Nick -- It does appear that the message got held up for five hours at groups.io, but I gotta admit that I don't know what CMGW means.

Are you the owner of TosaSpokesmen? If not, it's possible that the owners may have some of the subscribers on moderation and could be approving posts out of order. There are a handful of people in my own group who struggle to stay on-topic and I've found it necessary to put them on a moderation override.

I'm not aware of any recent groups.io system downtime...maybe someone else here has another explanation?

CMGW is Connection Manager Gateway.? I'd guess that there was a problem with GIO making a connection via the manager to secureserver.? The GIO site will keep trying to send emails until it's either successful or gets a bounce reply.

Duane,

I think CMGW must be a part of Nick's setup, not a part of Groups.io. Hence it still sounds like greylisting to me.

That is, it probably wasn't so much a problem making a connection as being given a 4xx "try again later" response from CMGW. Finally (five hours later) CMGW gave a 2xx "success" response and passed the message on to the rest of Nick's inbound chain.

In the screenshot, rows 0, 1, and 2 would be the inbound leg from Nick to Groups.io, 3, 4, 5, 6, and 7 would be the outbound leg from Groups.io to Nick's email interface.

I am the owner of the Tosa Spokesmen, and the people in question are not being moderated. In fact, one of the emails that was delayed was from one of our moderators! I don't have a funky setup here. I don't know what CMGW is, and its not something that I've configured.

I do have a custom domain with GoDaddy, but I am using straight email forwarding to Gmail. It does not hit a mailbox in between.

Nick,

I am the owner of the Tosa Spokesmen, and the people in question are
not being moderated.
I didn't think that was a factor with your issue, although delay pending moderation is frequently mistaken for a communication delay.

I don't have a funky setup here. I don't know what CMGW is, and its
not something that I've configured.
Nevertheless, I believe it is part of your inbound message path. In particular, that your custom domain specifies that server for receipt of emails addressed to you.

You may be able to verify this by analyzing the header of a message you received from some other source. The inbound path (last few hops) should be pretty much the same for all messages you receive.

The other reason I don't think that CMGW is part of Groups.io is that I've never seen it in the path of any message to me from Groups.io, and I've looked at headers I've received at two different services (Gmail and Dreamhost). My path is always direct Groups.io --> google.com or Groups.io --> dreamhost.com

I also have a domain on GoDaddy.? I've got an email account set up that uses secureserver.net.? It's not unusual to see messages come in that are up to 3 days old, but I don't use it for anything serious.
