email issues

 

I've been having some problems with my io groups over the past few days. I either receive the email messages late, or not at all, in random order, sometimes immediately after the message was posted, sometimes several hours later, sometimes not at all. I have checked whether my email address is bouncing - it's not. I have checked my server's spam filter to make sure they're not messing with stuff sent from io - nothing. I checked my settings, everything seems to be fine, but the problems persist. Even the groups I am owner or moderator on have the issues, and it seems to be just me. Other members seem to be receiving their messages with no problems. Has anybody else come across something like this before? Any ideas?

A number of things could be in play. Some providers (cox.net, rr/spectrum/charter) have a history of "throttling back" and delaying groups.io message delivery. I've also found that really short, "me too" messages are more likely to get held up and/or diverted to spam.?

The next time you get a delayed message, open the message header and paste it into the analyzer found at??. This will show where your messages are getting held up, and for how long...if it's your own provider then you will have a firm basis for a complaint to sanverse.net.

Good luck,
Bruce?

Missy,


I've been having some problems with my io groups over the past few days. I either receive the email messages late, or not at all, in random order, sometimes immediately after the message was posted, sometimes several hours later, sometimes not at all.

Except for the "sometimes not at all", this symptom sounds like what happens when your email service is using greylisting to test whether the sender is a spambot or not.

Possibly there's some other connection problem between Groups.io and your email service, but ultimately each message should either be delivered or be rejected (reported as "bounced"). It is very bad form if your email service accepts a message from a sender and then drops it in a black hole instead of delivering it to either your Inbox or your Spam folder. The "blackhole" treatment is supposed to be reserved for senders the service is quite certain are illegitimate (an ip address with no DNS record as a mail server, for example).

I have checked whether my email address is bouncing - it's not.

Which means that Groups.io has been able to connect to your service, and your service has been accepting the deliveries.


Any ideas??

Check with your email service to see if there's any way that Groups.io's outbound server (IP address 66.175.222.12) can be "whitelisted" or otherwise made exempt from whatever they may be doing that delays delivery.

So I just checked with the analyser (thanks a lot for that link, by the way), and thre was an 11 hour delay from web01.groups.io to ldn-srv1.filteredmx.net. The latter I am convinced is Kualo¡¯s spam filter, but I don¡¯t get why they would delay it. Either deliver or not¡­it¡¯s not a short message by the way, some of these are 500 ¨C 2000 words posts.

I¡¯ll get in touch with Kualo (who hosts sanverse.net), and see what they are playing at, especially since I¡¯ve been using io groups for years without issues.

?

Thanks for the support and information.
