[mailop] Outlook Asynchronous Bounces

Beginning today, we've observed a spike in asynchronous bounces -- messages initially accepted for delivery but then returned as a non-conversational bounce -- at Outlook domains (e.g. outlook.com, hotmail.com, etc.) with the following rejection syntax: 532 5.3.2 STOREDRV.Deliver; Missing or bad

Re: [mailop] GMail 550 5.1.1?

Yes, it started about an hour or so ago for us. Accounts that had delivered yesterday or even earlier today in some cases are now seeing that error. On Mon, Dec 14, 2020 at 7:00 PM Bez Thomas via mailop wrote: > Anyone else seeing repeated, but intermittent, 550-5.1.1s from Gmail for > valid

Re: [mailop] Microsoft Support Ticket Form not working

If you haven't already, try a different browser. I had similar, repeated issues, but using a different browser seemed to solve the issue. On Wed, Nov 11, 2020 at 12:44 PM Scott Mutter via mailop wrote: > Not necessarily a mailing issue - although, I do have an issue with > Microsoft blocking

Re: [mailop] List of unused, big email-domains?

+1 in being interested in that documentation. I have a relatively small list based on shutdown announcements from industry blog posts, e.g. what Al Iverson has compiled here: https://www.spamresource.com/search/label/dead%20domains On Tue, Jan 8, 2019 at 12:01 PM Benjamin BILLON wrote: > I'd

Re: [mailop] Gmail's "Why is this message in Spam?"

Gmail representatives at an industry conference explained two of the reasons as follows which are as you suspect: - "We've found that lots of messages from are spam" indicates poor domain reputation (or, likely as you have experienced, unknown / untrusted reputation). - "It's similar to messages

Re: [mailop] Earthlink trouble?

Not just you; also seeing a lot of "421 Load too high" errors here, as well as "421 *.earthlink.net Timeout waiting for data please try again later" rejections. On Mon, Jan 22, 2018 at 3:15 PM, Russell Clemings wrote: > I've been seeing a lot of this since about the middle

Re: [mailop] Issue with Gmail Postmaster
