+ | [11] HOW DOES THE SDF MAIL SERVER WORK? IS IT RELIABLE? HOW? | ||
+ | | ||
+ | | ||
+ | the TCP/IP SMTP (Simple Mail Transfer Protocol). | ||
+ | given time working on 25-50 incoming/ | ||
+ | of just under 200 messages (as of 31-Mar-06). | ||
+ | |||
+ | IS IT RELIABLE? | ||
+ | |||
+ | Yes, it is reliable. | ||
+ | If you are dying, please call 911. Do not use email. | ||
+ | you need to communicate something quickly, please call the recipient. | ||
+ | |||
+ | IF THE MAIL SERVER IS DOWN, WHERE DOES MY MAIL GO? DO I LOSE IT? | ||
+ | |||
+ | | ||
+ | to send email to a recipient SMTP server at a set interval for, | ||
+ | at the very least, 5 days before returning to sender. | ||
+ | |||
+ | SDF is configured to retry to send pending your outgoing messages every | ||
+ | 30 minutes for 5 days before returning them to you. | ||
+ | | ||
+ | | ||
+ | email just because the server didn't respond the first time, or the | ||
+ | | ||
+ | the good portion of a week for mail to be ' | ||
+ | You may assume that it works otherwise, but that just is not the truth. | ||
+ | |||
+ | SDF also has secondary MXes (Mail eXchangers) which can accept SDF | ||
+ | email during the very rare occassions that the primary MX is down | ||
+ | for maintenance or otherwise. | ||
+ | (UNIX to UNIX CoPy) and is polled by the mail server every 60 minutes. | ||
+ | |||
+ | DOES SDF FILTER EMAIL BY CONTENT? | ||
+ | |||
+ | | ||
+ | | ||
+ | | ||
+ | |||
+ | DO YOU BLOCK OR WHITELIST ANY SMTP SENDING SERVERS? | ||
+ | |||
+ | SDF, like other organizations, | ||
+ | The ORDB is a very reliable method of preventing reception from rogue | ||
+ | SPAM senders. | ||
+ | that are either purposely or accidentally configured to allow anyone | ||
+ | to send email to anyone through them. It also tracks senders that do | ||
+ | not have a PTR record (a DNS reverse look up pointer). | ||
+ | |||
+ | You possibly will still receive spam as it is an unfortunately | ||
+ | | ||
+ | | ||
+ | | ||
+ | |||
+ | We also feel that if you want to filter your own email, then it is up | ||
+ | to you. You also deserve to receive every email directed towards you | ||
+ | and we should not, in any way, censor or filter email destined to you | ||
+ | with exception of the highly regarded ORDB project. | ||
+ | |||
+ | We recommend that any filtering you do be done offsite. | ||
+ | email programs such as Mail.APP (MACOS X) will do a sufficient job at | ||
