Is the SMTP AUTH feature for "Domain-based relay" and "Default relay" supported? If yes, which authentication method does IMSS support? Parent topic

IMSS supports the CRAM-MD5, PLAIN and LOGIN SMTP AUTH authentication methods for "Domain-based relay" and "Default relay". However, you cannot configure the settings from the web management console. To configure the settings, set <auth>=1 to use the AUTH function and manually edit tsmtpd.ini as follows:
Syntax: 
[SmtpClient]
# for Domain-based delivery
RelayHostCount=1
RelayHost0=trend.com:guid0
D_guid0]
UseMethod=1
SmartHostCount=1
SmartHost0=<hostname_or_ip>:<port>:<auth>:<username>:<password>
# for Default delivery
[DefaultRelay]
UseMethod=1
SmartHostCount=1
SmartHost0=<hostname_or_ip>:<port>:<auth>:<username>:<password>
Example:
[SmtpClient]
# for Domain-based delivery
RelayHostCount=1
RelayHost0=trend.com:guid0
[D_guid0]
UseMethod=1
SmartHostCount=1
SmartHost0=192.168.1.1:25:1:user1:@trend.com:
!CRYPT!66AE674C2079B2CD00CAB0D02E765970
# for Default delivery
[DefaultRelay]
UseMethod=1
SmartHostCount=1
SmartHost0=192.168.1.2:25:1:user2@trend.com:
!CRYPT!66AE674C2079B2CD00CAB0D02E765970
