Emails to Yahoo are rejected - 01:36pm Aug 18, 2020 CDT - Hello Arron,

Thank you so much for your prompt replies and the great suggestion. I'll give the MX Cache file a try!

Update URLs to add to firewall - 11:38am Aug 18, 2020 CDT - Just to add to my original post, I am looking in particular for the URL that is used for updating the spam filter.

Thanks for your reply. I have looked at the URL provided but the information if not helpful, it doesn't define what is "unusual" activity and it does not state how long until mail is accepted again - just to wait 4 hours and try again. There is no information about how to contact them concerning the issue...

Emails to Yahoo are rejected - 01:36pm Aug 18, 2020 CDT - Hello,

I have just installed mdaemon v20 on a Windows Server 2019 box. Outbound emails seem to go fine except for anything to @yahoo.com or @yahoo.co.uk, which are all rejected:

Tue 2020-08-18 15:19:47.665: 02: <-- 421 4.7.0 [TSS04] Messages from ??.??.??.?? temporarily deferred due to user complaints - 4.16.55.1; see https://help.yahoo.com/kb/postmaster/SLN3434.html

The external firewall blocks inbound port 25 from all external IP addresses so there is no way anybody is using mdaemon to send spam and causing user complaints, and the server isn't sending particularly many messages (up to 2000 a day)...

AV Update fails with Error code (12057): unknown error - 09:59am Aug 18, 2020 CDT - Hello,

I have just installed mdaemon v20 on a Windows Server 2019 box that sits behind a firewall. The firewall blocks all outbound access unless they match specific "allow" rules. I have added a rule to allow access to *.mdaemon.com over https, but the AV update still fails (log is below)...
