SMTP Options Dialog |
The SMTP Options dialog allows you to specify additional options for the SMTP server, including authorization information, mail format verification, and a From Account. You can show the SMTP Options dialog by clicking the SMTP Options button in the Preferences dialog.
If an invalid header is found, the header name is prefixed with the string "X-Original-" (for example, a From header would be changed to X-Original-From). Note that your e-mail client will not recognize the modified headers.
Message lines that are too long are split into segments. Line breaks are inserted at a space character wherever possible.
Setting this option is not recommended unless your SMTP server is rejecting messages due to incorrect formatting.
