ClamSMTP enables virus scanning with ClamAV anti-virus software through SMTP filtering.
The ClamSMTP project is a must-have SMTP filter that enables you to scan for viruses using the ClamAV anti-virus software. This software accepts SMTP connections and forwards SMTP commands and responses to another SMTP server while intercepting and scanning the 'DATA' email body before forwarding. The objective of ClamSMTP is to be lightweight, reliable, and simple, instead of having a plethora of options. It is written in C without any significant dependencies.
However, if you require more options, you may consider using something more substantial, such as AMaViS, which is written in PERL and can do almost anything. This project was created with the Postfix mail server in mind. Configuring it as a Postfix Content Filter is straightforward.
Apart from being a content filter, ClamSMTP can also serve as a transparent proxy to filter an entire network's SMTP traffic at the router, making it an indispensable tool for network administrators.
Recent updates to ClamSMTP include adding support for embedded NULLs in email data, fixing Compiling warnings, and handling empty addresses in Logs, among others. Additionally, this release will address the problem of the server rejecting email messages during overload, encounters errors, or filter command failures.
In summary, ClamSMTP is an amazing SMTP filter that gets the job done quickly and efficiently, with the added bonus of being lightweight, simple, and reliable.
