That seems like it's something that handles showing message FROM addresses somewhat differently than just the FROM header. Perhaps looking at other headers if FROM isn't present, or how it handles multiple addresses? Or maybe acting as an automatic FROM or TO display, depending on which folder is being looked into. I really couldn't tell from my brief poking around at various folders with differently addresses messages to test against. The latter (auto FROM/TO display) seems to be what it's intended for, going by what I can read about it, with either inward or outward pointing arrows next to an address to indicate which direction. And only making sense for those with a mix of sent and received messages in the one folder (such as Gmail's abomination of dumping everything into one box, and you having to *search* for things). Anyway, that's just how it will list the emails present in whatever folder you're looking at. When you reply, the headers in the particular *message* will be paid attention to. > as for my replies it shows "Community Support" but for you is shows > "Patrick O'callaghan <[email protected]".

If a message has come from someone who's address might be a problem as far as anti-spam handling is concerned (for it, or list mail recipients), then it changes the details to its own email address. For many domain names, only *some* mail servers are authorised to send mail from that address (this will be all of their own mail servers, which won't include the list mail server). This is an anti-spam technique. Anything else purporting to send their mail from another server is conversely not authorised, with two common consequences: When going through servers that check for validity, the mail is marked as probably spam, and the mail *may* be automatically rejected. (*) The list server is authorised to send mail from its own address, so that's what it sends such mail addressed FROM. And it adds the sender's and recipient's address(es) in the CC field, which still allows someone to make direct replies if necessary. * The authorised mail server DNS records lists which mail servers are authorised to handle its mail, and can suggest that recipients of unuthorised mail should flag it as spam and let the recipient deal with spam handling, or that unauthorised mail ought to be automatically voided in some way (rejected or deleted) never being delivered to the recipient. The recipient mail server can follow those suggestions, or ignore them. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
