FWIW, I have 102 yahoo subscribers (86 are yahoo.com, others are around the world), and I do not recall seeing ANY yahoo delays at all in the last few weeks. I do get delays from hotmail (64 subscribers), and from places in China and Finland. One address at a Chinese university takes a day to clear, every time, but it is the only address at this particular university. Other delays usually clear within an hour or two.
It is hard to compare details since I use sendmail, and I see the delays in the mail queue (which I see by saying "mailq", as root). Sendmail seems to try to re-send the mail every hour, after two shorter attempts. I do set SMTP_MAX_RCPTS = 5, but I think you did that too. In sum, I'm not sure that this is something that yahoo does as a matter of policy. You might check to see if you are on any block lists: https://check.spamhaus.org/ https://mxtoolbox.com/blacklists.aspx Ignore UCEPROTECT3. Apparently nobody pays any attention to this seriously ugly list. Lots of sites use SPAMHAUS (almost as bad as UCEPROTECT3) for preliminary screening. Jon On 05/30/21 23:18, Stephen J.
