  • LOGIN · non-encrypted Base64 encoded passwords are used.
  • NTLM · Integrated Windows Authentication automatically provides credentials on Windows level.
  • CRAM-MD5 · specifies to use CRAM-MD5 authentication supported by some types of extended SMTP servers without TLS (Transport Layer Security).
Username Provide SMTP authentication username.
Password Provide SMTP authentication password.
Connection Choose between Regular and secure client and SMTP connection:
  • Regular · the connection is made over non-encrypted protocol.
  • SSL · specifies to use secure SSL connection with SMTP server.
  • STARTTLS · specifies to use secure STARTTLS connection with SMTP server.
Version Choose how client and SMTP server negotiates the version of TLS or SSL to be used in secure connection:
  • Auto · automatically chooses the best possible TLS version for a particular SMTP server.
  • SSLv3 · oldest version.
  • TLS 1.0 · deprecated by most servers.
  • TLS 1.1 · deprecated by most servers.
  • TLS 1.2 · the most supported version by most servers.
  • TLS 1.3 · the latest TLS standard.
TLS errors It is important to carefully assess all the risks by allowing TLS errors to be ignored in the production environment. Choose to either fail or to ignore any certificate errors caused when connecting to secure SMTP server using SSL or STARTTLS:
  • Strict · email sending will fail on any TLS error.
  • Ignore · usually it is fine to use self-signed SSL certificates and ignore related TLS errors in secure LAN environments, or when connection to SMTP server is secured by other means, such as VPN tunnels.
Use custom HELO greeting Provide text that will be used for HELO / EHLO greeting when initiating client and SMTP connection. If not specified otherwise, computer name is used for initiation of SMTP connection.
Connect using this IP address In case your machine features multiple connections to network, it is possible to choose which one will be used by providing Domain name or IP address of necessary interface.
