NotSpamFilter: Why are letters sent from my Gmail and Google Apps email addresses getting intermittently marked as spam in Outlook?
For six months or so, I've noticed at a great many of my letters have not reached their recipients. Personal correspondence. (No attachements, no forwards, no idiotic chain letters. I have NEVER sent a letter to more than two people at a time.) I chalked it up to problems with their ISPs, as letters sent from both Gmail AND my custom domain (hosted on Google Apps) were vanishing into the ether. (Once, a rejection letter -- reprinted below.)
I also considered that, perhaps, keywords in my messages were triggering problems. When writing about the novel "Oryx and Crake", for example, I can almost see how a filter might interpret that as gibberish and kill it.
In the past, Postini has blocked the occasional letter I've sent. (I tested by sending to my company address.)
Last night, I began an experiment. I sent a letter from my Google Apps account to my company email address, Live.com, Yahoo.com and Gmail.com. The letter made it to everyone EXCEPT my company.
Outlook's spam folder ate it. (I'm using the default settings.)
I resent the same letter through my standard @gmail address. Again, Outlook's spam folder nabbed it.
I resent the same letter through my @live.com address. It made it to my Outlook inbox.
I resent the same letter through my @yahoo.com address. It made it to my Outlook inbox.
SO... my question! Why are my letters sent through Gmail and Google Apps being flagged as spam, but not the same letter through other providers?
I'm going to be querying literary agents this week, and as you can imagine, it's very important that my letters not be eaten by a zealous Microsoft product. Must I switch email accounts? (The Live.com, Gmail.com and Yahoo.com addresses are not primary accounts for me, and I'd hate for my professional correspondence to have asinine "Check out MSN.com for the best weather forecast!" footers.)
For what it's worth, I've checked the MX servers on my Google Apps (all good) and have run my domain through this blacklist check
. Again, all good.
I can wrap my brain around a personal domain getting the evil eye from spam filters... but Gmail?
This is wearying and worrisome. Any insight will be appreciated.
(Upon reflection, if my writing style is reminiscent of junk email, it may not matter whether the agents get my queries or not.)
The only "email rejected" letter I've ever received, long ago, is below. I do not know if it is relevant.
