|
1. This module just uses Net::SMTP to try to deliver messages to peer MTA. If the remote mailbox doesn't exist, peer MTA will return a message such as "mailbox unavailable". |
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
2. Some email providers don't behave like above, such as Yahoo/AOL, so this module won't work for them. |

Please note, |

|
|

|
|
|
For many email providers, you have to provide the correct local hostname for sending email to them. The hostname must match: |
64
|
|
|
|
|
|
|
|
65
|
|
|
|
|
|
|
1. It is your valid domain/host name. |
66
|
|
|
|
|
|
|
|
67
|
|
|
|
|
|
|
2. The hostname has an IP address, and a correct PTR for this IP (PTR match back to hostname). |
68
|
|
|
|
|
|
|
|
69
|
|
|
|
|
|
|
3. The domain has valid MX records and/or SPF records. |
70
|
|
|
|
|
|
|
|
71
|
|
|
|
|
|
|
4. The IP has good reputation (not listed in any DNSBL). |
72
|
|
|
|
|
|
|
|
73
|
|
|
|
|
|
|
If you can't send messages to those providers, please setup your right localhost and localuser options in new() method. |
