Sage CRM SMTP Password Length Max

In trying to add our SMTP server, we first noticed that there's no support for SSL/TLS, but we found this post, community.sagecrm.com/.../7372.aspx, on using stunnel.

However, the next hurdle we encountered is that the Sage CRM HTML imposes a 24 character password length restriction:
<input type="password" class="EDIT" name="SMTPPassword" value="************" maxlength="24" size="25">

What's strange is the underlying database column does not impose this restriction: dbo.Custom_SysParams.Parm_Name SMTPPassword dbo.Custom_SysParams.Parm_Value is nvarchar(max).

Is there any way around this? For example, if you use Amazon SES SMTP, you must use IAM authentication where the Secret Access Key must be a 40-character sequence.

Thanks
