You must specify\r\nPOP3 username as username@target.host.ip[:port]\r\nport is 110 by default.\r\nExmple: in Username configuration for you e-mail reader\r\nset someuser@pop.example.org, to obtains mail for someuser\r\nfrom pop.somehost.ru via proxy.\r\nsmtpp SMTP proxy server, binds to port 25. You must specify\r\nSMTP username as username@target.host.ip[:port]\r\nport is 25 by default.\r\nExmple: in Username configuration for you e-mail reader\r\nset someuser@mail.example.org, to send mail as someuser\r\nvia mail.somehost.ru via proxy.\r\ntcppm TCP port mapping. Maps some TCP port on local machine to\r\nTCP port on remote host.\r\ntlspr TLS proxy (SNI proxy) - sniffs hostname from TLS handshake\r\nudppm UDP port mapping. Maps some UDP port on local machine to\r\nUDP port on remote machine. Only one user simulationeously\r\ncan use UDP mapping, so it cann't be used for public service\r\nin large networks. It's OK to use it to map to DNS server\r\nin small network or to map Counter-Strike server for single\r\nclient (you can use few mappings on different ports for\r\ndifferent clients in last case).\r\nmycrypt Program to obtain crypted password fro cleartext. Supports\r\nboth MD5/crypt and NT password.\r\nmycrypt password\r\nproduces NT password\r\nmycrypt salt password\r\nproduces MD5/crypt password with salt \"salt\".\r\nRun utility with --help option for command line reference.\r\nLatest version is available from https://3proxy.org/\r\nhttps://github.com/z3APA3A/3proxy\r\nPage 6 of 7\n\nWant to donate the project? https://3proxy.org/donations/\r\nSource: https://github.com/z3APA3A/3proxy\r\nhttps://github.com/z3APA3A/3proxy\r\nPage 7 of 7\n\n+ Linux and + Lite version derivered systems for Windows 95/98/NT/2000/XP/2003    \n+ 32 bit and 64 bit versions for Windows Vista and above, Windows 2008 server and above\n  Page 5 of 7",
