(At this time I am waiting for another non-responsive response from DH, it has only been 8 days since the support request was entered and about 3 months of problems in this area.)
Does anyone else have a problem with Dreamhost incoming mail servers bouncing your legitimate incoming email? You most likely you don't know you have the problem
I know of the problem ONLY because I subscribe to many discussion lists from Yahoo Groups (I dislike Yahoo, but that is a different matter) -- I get probably 30 to 50 list messages a day. Suddenly I don't get any, like someone turning off the faucet. I check with my groups page on Yahoo, and they have suspended sending messages to me due to "hard bounces" to my mailbox (on my Dreamhost hosted domain, you know, one of those m-numbered things). I then go thru the procedure of reinstating service. All is fine for maybe 3-4 weeks usually, then same thing repeats.
Fortunately, Yahoo (bless their heart on this at least) saves and gives you the "hard bounce" message. Here's the proof: (altered slightly to disguise my real email address and mailbox m number)...
The m9953885 mailbox above is doctored from the real number, but the one actually in the message is an established mailbox with dreamhost for over a year.
Of course, most mail gets thru, but who knows how many get bounced like that? Dreamhost so far just checks the operation of my mailbox, finds it works, and does nothing more. Anyone else have this problem or would even know about it? (I do not make use of any DH spam filters, etc.)
