So I'm just a volunteer who doesn't understand much about email systems.. just rudimentary - and I am managing an email list for community announcements and trade, by subscription only. We have about 1500 subscribers.
I have one problem that when a particular user (the city) sends an announcement, it tends to bounce hundreds of mainly one ISP's users.. that ISP being Alaska's GCI.com . Other users, say on hotmail, yahoo, etc.. don't get bounced. I manage the emails via gmail and lately I've been "locked out of gmail due to suspicious email activity" which is a pain in the rear. Also causes my host (Hawkhost) grief.. the overhead they dislike though they haven't complained lately. So I'm motivated to look into this a bit. Sometimes I do get this: host mx1.arandomserver.com [198.252.100.64] SMTP error from remote mail server after end of data: 550 Headers contain illegal BOM on my personal email from the same sender (city), but not sure that is same issue. The city usually includes a link to the city codes on a public webpage - perhaps that triggers GCI. I could post one of the headers in total but it is probably about 3 pages worth. Everything sort of looks ok to me except I notice this: BODY: Bayes spam probability is 0 to 1% [score: 0.0000] 0.0 RCVD_IN_DNSWL_BLOCKED RBL: ADMINISTRATOR NOTICE: The query to DNSWL was blocked. See http://wiki.apache.org/spamassassin/DnsBlocklists#dnsbl-block for more information. [34.212.96.103 listed in list.dnswl.org] -0.0 SPF_PASS SPF: sender matches SPF record 0.0 HTML_MESSAGE BODY: HTML included in message The link in the messages is https://www.codepublishing.com/AK/Nome/ . I can post more of the header if need be. Could it be that GCI needs to whitelist or something? thx, Jim ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
