<div dir="ltr">I understand the concepts of how email and listservs work, but I've only dabbled in setting up and working with simple mail servers myself and don't know all the nuances. But it seems to me that, while the problem is ultimately yours, the cause would have to be partly on the receiving mail server's side, in the sense of its rejection of inbound mail originating from your address (or from your mail server's IP address). If some people on the lists are receiving the mail from you, then you are <u>sending</u> without issue. If you're consistently being rejected by a listserve and nobody on that listserv is receiving your mail, then I'd look to the listserv as the one rejecting mail from your email address or mail server's IP address. If <u>some</u> people on the listserv are receiving your emails, then the mail is getting forwarded from the listserv and the mail would be getting rejected by the individual recipients' mail servers.<div><br></div><div>The only thing that makes sense to me is that your mail server's IP address has gotten itself on a block list that the would-be recipients' mail servers subscribe to....something you've already thought of and looked into. Maybe you haven't found the right blocklist?</div><div><br></div><div>Could a misconfigured DNS SPF record for your domain cause this, where the would-be recipients' mail servers are less forgiving than others?</div><div><br></div><div>I think you need the opinion of a mail server admin here.

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">I have found over the last year or more that when I send emails from my library account to some lists that some individuals on the lists are not seeing my emails, only the replies
to them from other list members. <u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">In the two particular cases where I am certain this has happened, both individuals who were not getting the originals were in academic libraries at relatively small colleges.
In one of those two cases, the recipient I know had more general technical knowledge than I do, which makes me think this isn’t just people not knowing how to find their spam folder.

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">My email is setup through Microsoft’s Office 365 Educational (I think they call the level “E1”), which is freely available to public libraries level. In the most recent case,
I have looked at least a few blacklist searches for our domain as well as our primary oplin IP address, and both show up as not listed.

of my work communications onto a personal account or maintain multiple work email accounts because of some vagary with O365..
