Postmaster and other role accounts not replying at all to email that they're sent is just not a good thing to do.This may give you an idea of what issue may be and the response you're likely to encounter. Back in June, we contacted Bellsouth postmaster regarding their filtering of SMTP connections (i.e., so that connection attempts hang until the timeout is reached), and received this reply from postmaster () bellsouth net: We will configure our settings for your company on our Filtering mechanism to 50 messages within a 5 minute window. We ask that you conform to this industry standards regarding submission of email to our mail server. As you all know, 50 messages/5 minutes is abysmally low, particularly for a mailing list hosting provider. Our requests for higher threshold and a pointer to the "industry standards" were summarily dismissed. If there's a Bellsouth contact with more of a clue on this list, we'd be happy to meet any reasonable requirements you have for email delivery. Omar Thameen omar () BIGLIST com
Bellsouth basically told me they were blocking Pair Networks because the percentage of spam vs non-spam is around 75 - 80%. They say they are communicating with them on this. Supposedly there was a conference telephone call this past Thursday 09-22-2005. BS says they must reduce this spam amount for the block to be removed. Pair seems to think it is mostly domain customers forwarding their mailboxes to their BS dot Net email accounts. This the first I've heard of BS having a 50/5 threshold limit. ---Alan Spicer (a_spicer () bellsouth net)
