Mail ehlo

CONFIG PARAMETER: mail_ehlo <string>

DEFAULT: None

Specifies the EHLO string to offer to the SMTP server. This is typically the DNS name of the sending host or something close, and SMTP servers are likely to perform a reverse-DNS lookup on the sender’s IP address, an MX lookup on the EHLO string, and make some judgement as to whether the sender is relaying mail.
