Due to the repeated unsolicited email originating from the following senders:
@iosr.us
@mail[1-9]iosr.org @iosrmail.org @mail[1-9]inv.com
we have started automatically directing email from those sites to the SuspectedSpam folder, with a label that says [BLACKLISTED]. If you need to receive email from that site please let us know and you can whitelist the required addresses (see our Email and Spam Filtering webpage for more information).
