Previously I had asked about my IP getting blacklisted. This morning I received bounced e-mails from people/servers that I did not send. The returned e-mails were bounced due to SPAM conditions or user is not valid. The e-mails all had my address as the sender, were addressed to people I do not know, had different subjects but all were generally the same message regarding ordering Viagra.

How is my e-mail address getting harvested. I have AVG 9.0 Internet security, use AVG on our e-mail serever for incoming and outgoing messages. and have checked our IP for open relay. Something is obviously capturing my e-mail address or going through our server.

What else can I do for protection or do to stop this?

The spammers are not neccessiary harveting your email address from your server.  I did a google search on "How Spammers Havest email addresses"  I got many results, but this first link seemed to sum it up:

Mail Server v1.0.8.3
  • Added support of STARTTLS (STLS) command for SMTP, POP3, IMAP, and SMTP relay and delivery, which will allow secure, fully encrypted connections, when possible;
11/6/2011 1:10:34 PM
Mail Server v1.0.8.2
  • Optimized delivery speed. In earlier versions each "tick" which was checking whether messages were in the outbox queue, was picking up only one message at a time. Now it will attempt to pick MaximumAllowedThreads-ActiveDelivery threads messages, which should considerably increase deliver speed;
  • Optimized SEARCH and STATUS IMAP commands. They appear to be used very extensively by Android, and (not that extensively, but still) by iPhone. Now users who use mobile phones to access their IMAP accounts will see considerable improvement;
  • Optimized STORE IMAP command. Before storing of IMAP flags was occuring one message at a time, which seemed to be fine with SQL server, but proved to be slow for SQLite... Now it happens with single SQL call.
10/8/2011 7:59:35 PM
ArGoSoft Mail Server v1.0.8.1
  • Fixed a bug: when using IMAP via Firefox with "When I delete a message, move it to Trash folder" option, marking messages in the trash folder was causing high CPU usage, and was taking some time, making the server pretty much non-responsive. The problem was happening only when using SQLite.
6/6/2011 9:33:36 PM
ArGoSoft Mail Server v1.0.8.0
  • Fixed a problem with web interface - was showing only first page of messages, and would not switch to other pages; In order to fix the web interface, mail server itself has to be updated;
  • When installint initially, was still using SQLite, even when SQL was requested;
  • There was a problem with switching from SQLite database engine to SQL server database engine: the SQL database was not being created;
5/23/2011 5:53:55 PM
ArGoSoft Mail Server .NET v1.0.7.9
  • The server no longer requires Microsoft SQL Server. If SQL server is not found, it will use SQLite engine, which does not require separate installation. If SQL server is found, then user will be prompted whether he wants to use it;
  • Made other improvements, such as, now mailbox rebuild indexes orphaned records, rather then deleting them, also added an opotion to increment UIDL validity of folder (both on the Mailbox viewer box);
  • Made minor improvements on web interface;
