====== E-Mail Blacklist Issues ======

Because SDF is a public unix, there are many users, and many emails being sent.

Sometimes, some users can get SDF into trouble with their actions, unintentional or not. When this happens, you may not be able to send emails to people at some other Internet Service Providers. You may get emails with subject //Returned mail: see transcript for details// including error message like the following after sending mail to these correspondees:

  * (reason: 550 5.7.1 Unfortunately, messages from [205.166.94.20] weren't sent. Please contact your Internet se...ail.live.com/mail/troubleshooting.aspx#errors.
  * 421 4.7.0 [TSS04] Messages from 205.166.94.20 temporarily deferred due to user complaints - 4.16.55.1; see https:%%//%%help.yahoo.com/kb/postmaster/SLN3434.html.. Deferred: 421 4.7.0 [TSS04] Messages from 205.166.94.20 temporarily deferred due to user complaints - 4.16.55.1; see https:%%//%%help.yahoo.com/kb/postmaster/SLN3434.html
  * The following addresses had permanent fatal errors... (reason: 554 resimta-ch2-19v.sys.comcast.net resimta-ch2-19v.sys.comcast.net 205.166.94.20 found on one or more DNSBLs, see http:%%//%%postmaster.comcast.net/smtp-error-codes.php#BL001000)

If this happens, aside from contacting //membership// on [[=bboard|bboard]] //REQUESTS//, you can also try to get SDF off the blacklist for your emails to your correspondee.

Fill out forms for the following ISPs. //you may need to create an account of your own on the target ISP so you will also be a customer//. You should go ahead and represent yourself as a representative of SDF.

Stuff to know:

  * SDF server mail IP = **205.166.94.20**
  * SDF mail server IP = **mx.sdf.org**
  * SDF mail reverse DNS = **mx.sdf.org**
  * SDF mail contact, //you// and/or membership@sdf.org

one thing that helps is to send email between sdf and google with the 
subject "is gmail broken again?" and put that message in the body as well.
After a while it correct[s] whatever issue gmail has.
