MailServ provides a World Wide Web interface to several types of mailing list servers. Users can select commands, enter information, and press buttons to send email commands to the mail server. MailServ does not provide the actual mailing list services (you'll need to have an existing mailing list management program to do that), but what do you expect -- MailServ is free!
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
