Thank you to all who answered. I learnt from each of the three emails.

not working smtpd_recipient_restrictions implementation
Dear fixers, My postfix ability has dissapated over many years without use :-( I tried and failing to REJECT an unwanted domain from accessing postfix through this in main.cf smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_sender_access hash:/etc/postfix/sender_access, reject_unauth_destination, reject_rbl_client zen.spamhaus.org, reject_rhsbl_reverse_client dbl.spamhaus.org, ... /etc/postfix/sender_access example2.org REJECT unwelcome.tld REJECT END % postmap /etc/postfix/sender_access % ls /etc/postfix/sender_access* sender_access sender_access.db % sudo postfix restart I wonder if there are any clues here to what I am doing wrong or where I might try to fix this. Thank you in advance and best wishes Eric
delay all email to a defined sender list
Hi List, It happened just one time too many today, in a rushed moment sending the wrong email to the wrong person. Is it possible to exclusively delay sending mail to specific recipients that appear on in a list? This way I suspected such an error of an email to one the special recipients, then I could still delete the email from the queue. Best Eric
configuration of mailman with postfix

Re: receiving yahoo mails fails every so often
The problem is this yahoo and yahoo alone fails to make connections, the problem is random,most emails come through just fine, the specific failures are not repeatable. But an parker of ours uses yahoo business serves for their email, they are getting timeout bounces on 1 in 10 emails sent to us. That is the best description that I have for this issue. As for the verboseness I added this debug_peer_list = yahoo.com to main.cf. It fails with this off as well. If its a local disk race condition why only yahoo and not any other domain. If its DNS issue, why yahoo and no other domain? I had thought that its a firewall mucking the TCP packets, no avail.

Re: receiving yahoo mails fails every so often
This box does one thing only cleans email before forwarding onto an exchange forest. The system is over kill, quad core intel, 16GB memory, hdd is a velociraptor. This is for a network on which we get around 1 email every second. System load never gets 0.1. DNS are two servers both on gigabit on diff networks. All of the body checks are post queue, done by amavis. Will check synchronous syslog, but given the lack of load, not that hopeful. No its a problem up stream, one that tcpdump will help me get an answer.

yahoo sending to me is timing out
Hello postfix world, I seem to be receiving all of my emails excepting some from people who have emails with yahoo email acounts.They are either taking up to 20 hours in yahoo's queue or being returned. The postfix is a spam filter (amavis/clamscan/SA) for an exchange forest of 55 users, not many, so not much of a load. I am not getting any reports from other legitimate domains sending us emails having this issue. I have tried a bunch of things found on the internet, but the errors still exist. This was not a problem on my prior filter build on postfix 2.2.10. I had generally ignored such errors as my thinking was that these were caused by poorly designed bots, that may be a mistaken assumption with this more current postfix. I am thinking that there is more controls that I might be missing. So please find below an error from a client at yahoo, examples or the errors in postfix logs and my postfix -n output. Thank you for any help or insights that you may have! Eric Client errors are like this, Sorry, we were unable to deliver your message to the following address.
