Yesterday our company experienced a short period when outgoing emails were denied. I query Spamcop's (bl.spamcop.net) for our IP: 220.127.116.11 and it returned a positive that we were listed on SCBL.
This morning, we were still on the blacklist. This afternoon about 1pm CST, we were delisted.
This morning I called our ISP and they said to contact Spamcop? I thought they would be responsible for this since they give us the IP address? Anyhow, I don't want to play tug-a-war with them on the issue. Our company has been in business for 30+yrs, this is the first time we're experience this. There isn't much information I can post from the listing info. to say what actually "cause" us to be on SCBL. I do remember the cause was rather "vague".
I've checked and tested our Email server and it does not allow Relay. I'd like to know if anybody can help provide information why we were on Spamcop Blacklist, as to prevent this in the near future. Or point me in the right direction.
