|
* A multipurpose method
|
|
1017
|
* The method works in three ways, dependent on argument value and current state
|
|
1018
|
* 1. HELO/EHLO was not sent - returns null and set up $this->error
|
|
1019
|
* 2. HELO was sent
|
|
1020
|
* $name = 'HELO': returns server name
|
|
1021
|
* $name = 'EHLO': returns boolean false
|
|
1022
|
* $name = any string: returns null and set up $this->error
|
|
1023
|
* 3. EHLO was sent
|
|
1024
|
* $name = 'HELO'|'EHLO': returns server name
|
|
1025
|
* $name = any string: if extension $name exists, returns boolean True
|
|
1026
|
* or its options. Otherwise returns boolean False
|
|
1027
|
* In other words, one can use this method to detect 3 conditions:
|
|
1028
|
* - null returned: handshake was not or we don't know about ext (refer to $this->error)
|
|
1029
|
* - false returned: the requested feature exactly not exists
|
|
1030
|
* - positive value returned: the requested feature exists
|
|
1031
|
* @param string $name Name of SMTP extension or 'HELO'|'EHLO'
|
|
1032
|
* @return mixed
