At Pro Webmasters I searched for an issue which relates to spammed domain list for sending emails which end up in the Spam box in Gmail. I found the link something like below:
which says the reasons for the domain being listed as spam and I hardly found any solutions to come out that problem for the domain which was affected.
In my scenario the mails from my domain from the last few days are landing in SPAM box in Google whereas the rest like Yahoo/MSN/Rediff are OK. Even the plain text emails are going to SPAM Which is something of a surprise to me. I tried to find out the solutions overcome this problem but nobody gives exact steps to follow to solve this issue.
I request fellow members not to close this as duplicate, if you read my problem you can understand that this thread is all about steps to solve the issue of SPAM not the reasons. If you find similar questions please let me know or else try to answer my question.
