moderated Re: DDoS against our DNS servers #outage

 

Hi All,

I realized I didn't follow up with this. The attack stopped about 45 minutes after it started. We had DNS issues for about 5-8 minutes at the start of the attack before I could mitigate it. 

The DNS servers normally see 200-300 requests/second. During the attack, we were seeing 6k requests/second.

Everything should be back to normal.

Also, your puns are awful. I love it.

Thanks,
Mark

Oh no Mark, this is not good. I surely hate this. I hope that it is resolved soon.

moderated Stricter treatment of invalid hashtags #bug

Peter Cook
 

This seems to me to lie somewhere between a suggestion and a bug.

We use hashtags a lot in my premium group, which is set up so that members can only use existing hashtags; if an invalid hashtag is used. the message is kicked back. But if someone puts a hashtag in the subject line and inadvertently follows it with a punctuation mark (for example, "#FREE:" instead of the valid hashtag "#FREE"), the message is not kicked back. It goes right on through and of course the string is not recognized as a hashtag. However, if someone were to send a message with the string "#FREEP," it would be treated as invalid. 

I'd like to see stricter rules so that any string in the subject line beginning with # is seen as an invalid hashtag unless it corresponds precisely to an existing one. So "#FREE:" would be treated as an invalid hashtag just as "#FREEP" would, and the message would be kicked back.

Pete

moderated approval message loses and alters formatting #bug

Glenn Glazer
 

For example, in a recent Message Approval email, a line looks like:

*So, at our meetings starting on 3/24, we're going to use the Zoom waiting
room feature. Guests will be respectfully asked to identify themselves and
will be admitted into the session when they do so.*

whereas in the approved email sent out to the group, it looks like:

So, at our meetings starting on 3/24, we're going to use the Zoom waiting room feature. Guests will be respectfully asked to identify themselves and will be admitted into the session when they do so.

In case the formatting of this email gets mangled, in the first case the text is surrounded by asterisks and formatted to a short (80?) column width and in the actual email, it is properly underlined and there are no inserted line breaks.

Best,

Glenn

moderated On hashtag definition screen, make Lock Topic subordinate to Topic Duration #suggestion

Andy Wedge
 

Hi Mark,

To avoid confusion between Lock Topic and Locked on the hashtag definition screen, can we make the Lock Topic checkbox subordinate to the Topic Duration and only active when the Duration is something other than Forever?



Making Lock Topic active only when the Duration is changed would keep that option in line with recent Advanced Preference changes regarding Following Only and First Message Also etc. As it stands, Lock Topic can be checked on its own but has no effect.

Thanks,
Andy

Even the spamcop site says that email providers should NOT depend solely on their service.  Setting up a whitelist for users to add to is one of their recommendations.  I'm pretty sure the providers that have serious problems are only using spamcop and no additional filtering.

This appears to have been a situation caused by one group owner.  They direct added a spamcop honey trap address that triggered the whole thing, then did it again at least once.  IMNSHO, blocking an entire site (GIO) due to one group's indiscretion is way overboard.

Marv,

 

The blocking of several thousand e-mails because a couple of SPAM items gets sent is totally disproportionate.

Then as I am sure it, or its users need to white lists gmail, yahoo & Microsoft (Hotmail, outlook) where some spam originates,

The real nasties still seem to slip through. I think the blacklist approach is totally broken.

Early on in this thread, I thought that Spamcop was not acting responsibly and considered doing some research, then complaining to my email provider. As this unfolds, I have started to change my mind. Blocking the groups.io server temporarily might have been a little precipitate, and certainly annoying to many groups.io users, but, on the whole, perhaps warranted.

I hope I am not abusing this forum by asking, but how do others feel about Spamcop? Worth raising a fuss about, or not? Best, Marv

Hank,

If your group is set for restricted membership then you can create a Pending notice (see https://groups.io/helpcenter/ownersmanual/1/managing-member-notices/pending-subscription-notice) which will be sent automatically to a new subscription request. You have to explicitly make the notice active, there's no default notice.

It's a type of Member Notice that you would need to define.

I am not sure as I have not seen a pending subscription message.  Nobody has supplied additional information yet, though.
