protocols - Some questions about SMTP RFC -


I have two questions about SMTP RFC:
  • Which logic should I pass as argument?

    The domain name given in the EHLO command should be either a primary host name (a domain name that resolves an address for RR) or, if the host does not have a name One word is literal as described in Section 4.1.3, and further discussion is discussed in the EHLO discussion of section 4.1.4.

    I can not really remove section 4.1.3. Can you give me an example or write it again?

    • Which headers are required to be sent to the data class?

      Thanks in advance.

      The reasoning of EHLO in the absence of a domain name says

      section:

      Sometimes a host is not aware of the domain name system and communication (and, in particular, reporting communication and improving the error). To bypass this barrier, a specially lexical form of address is given as the option of a domain name. For IPv4 addresses, this form uses the four small decimal integers separated by dots and is enclosed by parentheses such as [123.255.37.2], which indicates an (IPv4) Internet address in the sequence-to-octet format .

      then a simple EHLO [123.255.37.2] sufficiency (with the actual IP address of your SMTP server) or rather a properly formatted IPv6 Could.

      Required Header

      section says:

      Only required header fields, date of birth fields, and provider address fields (s) Header field syntax is optional.

      Therefore, only to: and date: are required.

c# - ASP.NET MVC - Attaching an entity of type 'MODELNAME' failed because another entity of the same type already has the same primary key value -

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.

I use Django 1.6.5 with settings in my program txsite: DEBUG = true I set the lie to debug, but when I get the runner , I get the following error: CommandError: You have to set the settings.
