- Multi-threading allows up to 12 concurrent POP3 download tasks. The POP3
mailboxes are dynamically scheduled among the tasks depending on
download speed and message volume.
- Supports automatic mail routing for multi-user POP3 mailboxes
- Automatic mail routing using visible or hidden message headers. If
relevant information is available in hidden message headers, you can
reliably achieve automatic mail routing even for BCC-addressed
- Supports multiple users for a POP3 mailbox with a single SMTP
address. Message routing depending on keywords in the message subject
or the comment par of the email address.
- Optionally can leave messages on the POP3
server after download. Useful for roaming users, or people
who read their mail from more than one location. To keep the
POP3 mailbox tidy, messages
beyond a certain age can be removed automatically.

feature is useful to avoid automatic read receipts which would
otherwise be sent by older Microsoft Outlook versions.
Or which would break the
standard RFC2822 message format.

the sender of an incoming message in the following circumstances:
a message is sent to an unknown address in your messaging domain,
a message is sent to somebody who left your organization.

cases, the templates used to construct the notification messages can
- Write a log entry for each message.
Content-checking of incoming mail
- Anti-Spam analysis with
(an award-winning open source spam filter).
- Check the contents of messages : define a set of rules to determine
which messages should be intercepted, or which messages should not be
intercepted (this is useful to define exceptions with respect to other
rules). Check for attachments, active content in HTML messages,
the sender's name or address, hidden message headers, or words in the message subject.
For each rule you decide what should happen: send a notification,
the message, or the encapsulated message to the destination and/or
other destinations. Or send a customizable notification back to the sender of the message
(this can also be used to make an auto-responding system).
Or just delete the message.
- Scan messages for viruses: use a file-based
real-time virus scanner, which may already be protecting shared
folders on one of your file
Outgoing mail transfer
- Supports secure SSL/TLS connections.
- Use a SMTP relay server which requires authentication (AUTH LOGIN, CRAM-MD5 and more). Authentication depending

depending on the sender's email domain.
