/** |
|
14
|
|
|
* Holds extra information about a parsed Received header part, for FROM and BY |
|
15
|
|
|
* parts, namely: ehlo name, hostname, and address. |
|
16
|
|
|
* |
|
17
|
|
|
* The parsed parts would be mapped as follows: |
|
18
|
|
|
* |
|
19
|
|
|
* FROM ehlo name (hostname [address]), for example: FROM computer (domain.com |
|
20
|
|
|
* [1.2.3.4]) would contain "computer" for getEhloName(), domain.com for |
|
21
|
|
|
* getHostname and 1.2.3.4 for getAddress(). |
|
22
|
|
|
* |
|
23
|
|
|
* This doesn't change if the ehlo name is an address, it is still returned in |
|
24
|
|
|
* getEhloName(), and not in getAddress(). Additionally square brackets are not |
|
25
|
|
|
* stripped from getEhloName() if its an address. For example: "FROM [1.2.3.4]" |
|
26
|
|
|
* would return "[1.2.3.4]" in a call to getEhloName(). |
|
27
|
|
|
* |
|
28
|
|
|
* For further information on how the header's parsed, check the documentation |
|
29
|
|
|
* for {@see \ZBateson\MailMimeParser\Header\Consumer\Received\DomainConsumer}. |
