Ipswitch IMail is prone to multiple remote vulnerabilities. Attackers may exploit these issues to deny service for legitimate users, obtaoin potentially sensitive information, and execute arbitrary code.
The vulnerabilities include a directory-traversal issue, two remote denial-of-service issues, and multiple buffer-overflow issues.

Block external access at the network boundary, unless external parties require service.
Restrict access to the affected software at the network perimeter. Grant access for trusted hosts and networks only.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
NIDS may detect some attacks resulting from this vulnerability. Flag on excessively long requests and directory-traversal sequences. Webservers, application servers, and proxy servers also provide various logging facilities that may include evidence of attacks. Audit all applicable logs regularly.
Run all software as a nonprivileged user with minimal access rights.
Running the affected service as a user with least privilege possible may help mitigate the impact of a successful exploit attempt.
Implement multiple redundant layers of security.
Memory-protection schemes such as non-executable stack/heap configurations and randomly mapped memory segments will complicate exploitation of memory-corruption vulnerabilities.
The vendor has released a fix to address these issues.
Sebastian Apelt is credited with the discovery of one the denial of service issues. iDEFENSE Labs also discovered a denial of service issue. The rest of the issues were discovered by anonymous researchers.
