That is not flush, it deletes all mails in queue. Examine why messages stay in queue and do not get sent. Code: systemctl --state=failed See mail.log what it says about those messages in queue, there should be reason why it is not delivered. What commands? My signature has link to e-mail setup tutorial, it is for ISPConfig but has Troubleshooting chapter.
Sir, Thank you for the reply. I noticed, that the emails in the queue were all incoming & not the outgoing. To stop, I suspended one particular email id to which all incoming emails coming from different senders(spam) Now it is okay & no errors in incoming/outgoing. May I know, how do we block these incoming spammers, though my fail2ban is working very much Thanks
fail2ban does not examine incoming e-mails and does not block spam messages arriving. Install RSpamd or similar spam blocking application. Then tune it so it blocks those e-mails you do not want. There are umpteen tools to block spam, but none of them work 100%.
