Emails to me at my Juno address have suddenly begun to be bounced back to the senders who are attempting to email from a particular business address. If I am emailed at my Hotmail address though, the messages come thru just fine. I forwarded Juno an error/bounce message which was received by one of the senders, and this is what they tell me:
"Mail from the IP [number] was blocked because it triggered our anti-spam limits. Please be assured that we have contacted the domain authorities and are working with them to resolve this problem as soon as possible."
Only Juno can really answer that.
Something in their spam filtering system\software may have gone haywire and is identifying the particular senders IP address as a known source of spam thus kicking it back.
Sometimes a particular hyperlink (known spam source) inserted in an e-mail message will cause the same thing. It appears from that message they are aware of the problem and are working on it.
It may be that Juno has a quantitive limit set to the number of E-mails from one source before it filters them out as SPAM. Many ISPs for example, have such a limit to the number of Emails you can send within a certain period, as a way to eliminate Spammers. If many people send you E-mails, but all from the same address, it might block them.
Whereof one cannot speak, thereof one should be silent.
Thanks, you two. The particular business address that is getting the bounces only involves an email or two per week to me at the Juno addy, adding to my puzzlement.
Unless it would be unnecessarily plugging up this wonderful site, I'll come back and post the results, after Juno follows up.
