Yep, that's pretty much the answer I got.

Well it was pretty obvious on my server when my log file doubled in size
from about 4.5 Megs to 9 Megs. You can just occasionally look at the logs
and check what the STMP module is accepting. I didn't want to scare
anybody, but make people aware of what kind of abuse can happen with Post
Office.

>>Betreff: Post.Office and spamming
>>
>>Hello,
>>
>>Well this is a little off topic but I know there are a number of Emerald
>>users that are using Post.Office as their email program. The other day I
>>noticed that my Post.Office mail server was working pretty hard. As I soon
>>discovered, some mass mailers were redirecting spam to my mail server for
>>distribution. These guys were logging into Earthlink.net and had specified
>>my Post.Office mail server as the mail gateway for their spamming. So they
>>would post a message to Earthlink, earthlink would forward it to me, and my
>>server would mail out spam all over the net with my mail server's address.
>>Boy I was pissed when I found out. I had been handling an extra 5000-10000
>>messages a day for these spammers.
>>
>>But here is where I really got upset. I contacted Software.com asking what
>>I could do to stop this kind of activity. They informed me that
>>Post.Office can NOT filter this stuff out and I'm stuck with these spammers
>>for the time being. So I'm looking at switching to sendmail or something
>>else that can filter out SMTP accepts for message delivery to non local
>>domains. So if you are using Post.Office, you should be aware of this
>>vulnerability to spamming. I suggest you write Software.com and encourage
>>then to come up with a fix before your site gets targeted by spammers.
