1)What are the types of emails in postfix queue that would be set to MAILER-DAEMON? Is it all undeliverable mails? Or we can add in extra criteria to set incoming mails to MAILER-DAEMON (& how)?
2)I think it takes several hours currently to set undeliverable mails to MAILER-DAEMON. Where/how to find out the current setting for number of hours it takes that's currently in effect? 3)Can I set different timings, say for mails with mailbox that's full, it takes 2 days while for invalid email addresses/domains, it will take 1 hour? Thanks Roger
