I have one person with whom I correspond a lot and for some reason all his emails(he uses two different ones(private domain, and a gmail account) are bounced saying that they are spam. The text from the messages say: --------beginning of email text-------------- This message was created automatically by mail delivery software. A message that you sent has not yet been delivered to one or more of its recipients after more than 24 hours on the queue on se25.mailspamprotection.com. The message identifier is: 1odXb1-000477-7G The date of the message is: Wed, 28 Sep 2022 09:59:30 -0400 The subject of the message is: =?UTF-8?Q?Re=3a_Commande_resto_v=c3=a9go_pour_livraison_jeudi?= The address to which the message has not yet been delivered is: [email protected] No action is required on your part. Delivery attempts will continue for some time, and this warning may be repeated at intervals if the message remains undelivered. Eventually the mail delivery software will give up, and when that happens, the message will be returned to you. ----------end of email text--------------------- Maybe other people get bounced for the same reason and I do not know. There is a white list in ISPConfig, and both of his emails are on this list, but yet, emails are still bounced at a rate of 100%. Might you have some ideas? Thanks fo rany help Joseph
If you use rspamd in your setup you might want to check /var/log/rspamd/* logfiles and grep for the mail in question to see what scoring was applied. Like this: Code: # grep "[email protected]" /var/log/rspamd/rspamd.log 2022-10-26 07:00:38 #47527(rspamd_proxy) <98c65b>; proxy; rspamd_task_write_log: id: <XXXXX>, qid: <21D0C80511>, ip: XXXX, from: <XXXXXX>, (default: F (no action): [2.78/11.00] [MANY_INVISIBLE_PARTS(1.00){10;},URI_COUNT_ODD(1.00){55;},DMARC_POLICY_ALLOW(-0.50){XXXXXX;none;},MID_RHS_NOT_FQDN(0.50){},MV_CASE(0.50){},ZERO_FONT(0.50){5;},FORGED_SENDER(0.30){XXXXXXX},R_DKIM_ALLOW(-0.20){XXXXXXX:s=kl;},R_SPF_ALLOW(-0.20){+ip4:XXXXXXX/17;},MIME_GOOD(-0.10){multipart/alternative;text/plain;}, ... You see the action and scoring that got applied "(no action): [2.78/11.00]", and see where the scores come from. In this example the symbol MANY_INVISIBLE_PARTS added a score of +1.00.
