IceWarp Software - intercepting my email? how to eliminate?!

Posted on 2004-09-10
Last Modified: 2008-03-04
Hi, i recently have been getting a message every time i try to send an email from my private address (using mozilla thunderbird). It tells me:

"you have attempted to establish a connection with "" however the security certificate presented belongs to IceWarp Software. it is possible, tho unlikely, that someone maybe trying to intercept ur communication with this website"

it then proceeds to tell me to contact my site administrator. i did, and they know nothing of it and told me its not from their side. i've also scanned my comp for viruses, and used spybot and adaware and have found nothing. i don't know exactly how i got this on my email, but i have suspicions that may be from a mass email a friend sent to me. i forwarded it to some other friends (around 7 people), and that was the first time this warning message came up, at the time i clicked yes - to go ahead and send, and i believe i sent one other email from that account after that point, and a day or so later my administrator contacted me to warn me that i'd been spamming people from my account!!!

i have not been using this account since that point, have not found a way to resolve this and get rid of this icewarp certificate, i would highly highly appreciate any suggestions anyone can give me on how to resolve!

thanks in advance!

IceWarp is a Certificate Authority (CA), or "trusted 3rd party" certificate issuer (see their website at --> However, because they aren't one of the "big boys" CAs (liek VeriCrooks, Thawte, et. al.), ThunderBird did not intrinsically recognize them as a CA. Consequently, you had to confirm their certificate as acceptable by Thunderbird. Once you did that (assuming you did instruct it to accept it permanently), it was added to Thunderbird's CA listing and Thunderbird won't prompt you again.

I don't think it had anything to do with the alleged spam.

Note I say "alleged". A "feature" of modern SPAM/viruses are that they often forges headers so some other poor slob gets the blame, because everyone knows that computers can't lie, and if the TO: line says it came from, well, Bob musta sent it, right?

Ask to see this alleged SPAM - and ask to see the full headers. Did it realy originate from your network, or are the headers forged to make it look that way. If your site's administrator can't produce it or can't figger it out, well, then perhaps s/he should consider a career elsewhere. This is Internet E-Mail 101.

Either the certificate itself is defective or the server admin did not set it up correctly. Dunno.

Well, you did get rid of it when you deleted it from Thunderbird's certificate database. Trouble is, since the E-Mail server to which you are connecting is using it, Thunderbird keeps wanting to add it back.

The issue lies with the mail server to which you are connecting. The admin is the only one who can explain exactly what is going on and why.
