How bounce mail with error
Hi all! Almost configured postfix on my lan, I can't discover how bounce mail when the size attachments is too big to destination server. i.e. I send an email with attachments 30Mb to @yahoo.it, @tiscali.it by mailq I see the error: destination server can't accept that mail because the attachments is too big. I need that postfix bounce that mail to sender of mail. Otherwise, my users can't known if email is correct sent. any idea? thanks! Pol

block spam mail from lan
Hi folks! I'm newbie and I study postfix What I should be use to (check) and block attempt spam from my lan to internet?

Situation: A real user using browser connect to squirrelmail and send a mail. It's ok. But if this user create a mail bomb using squirrelmail how way to spam I can have this problem. If a drop port 25, user can send any mail. Or tell me what I don't understand. Thanks!

HI and thanks for your reply :-) I've this line: mailbox_command = /usr/bin/procmail -a "$EXTENSION" DEFAULT=$HOME/Maildir/ MAILDIR=$HOME/Maildir How add "fred" to /etc/aliases? ie: postmaster: root (but root of primary domain) fred --> is virtual user (second.domain) and if I've 3 domains with 3 same username: f...@domain1.com, f...@domain3.com, f...@domain3.com, how resolve? > But, you also use virtual_mailbox_domains etc. Why do you use > local(8) for mailbox delivery? where I check what I use for mailbox delivery? thanks!

exclude 127.0.0.1 from smtpd_tls_auth_only = yes
Hi all! I forced postfix to uses smtpd_tls_auth_only = yes but I need exclude TLS from 127.0.0.1 I known there's a change to do in master.cf but I don't know how resolve any idea? thanks! Pol
Re: exclude 127.0.0.1 from smtpd_tls_auth_only = yes
Thanks for your reply :-) I added 127.0.0.1:submission inet n - - - - smtpd -o smtpd_tls_auth_only=no to master.cf but I've same problem... thanks Pol

notify_classes
Hi all :-) I using notify classes: notify_classes = bounce, 2bounce, data, delay, policy, protocol, resource, software postmaster receives correct "alert" emails I'd like have also a notify when a local user send an email and there's an error (something like remote smtp does not run - for purpose test only) so I've a queue with something like: -Queue ID- --Size-- Arrival Time -Sender/Recipient--- 5584A7590AF 1012 Sun Jul 7 18:04:00 us...@example1.com (connect to domain3[35.120.217.165]:25: Connection refused) us...@domain3.com Is notify_classes does this? Better if postfix send an "alert" to sender user with error (in this case "connection refused"). So user can known that the mail is not sent (for now). Any idea? Thanks! PS: I reading postfix "the definitive guide" - thanks Wietse :-) Pol

delivery status notification (DNS)
Follow official postfix page (http://www.postfix.org/DSN_README.html) I've: smtpd_discard_ehlo_keyword_address_maps = cidr:/etc/postfix/esmtp_access cat /etc/postfix/esmtp_access # Allow DSN requests from local subnet only 192.168.1.0/24 silent-discard 0.0.0.0/0 silent-discard, dsn ::/0silent-discard, dsn I've small lan on 192.168.1.0 and all clients uses a single smtp postfix server. On clients, send the emails with "delivery status notification" option. After sent, postfix send me a delivery status notification: Successful Mail Delivery Report but that email is within postfix queue (why I stopped destination over internet smtp server - purpose test). So, my postfix server always send a delivery status notification also if there's a transmission problem. What's the error? thanks! Pol
Re: delivery status notification (DNS)

multiple relay
Hi all :-) I'm not sure which parameters is correct, I've: pc1 - user1 pc2 - user2 pc3 - user3 I need set postifx with multiple relay: if user1 send an email to domain1, postfix should be send using mail.server1.org with sasl. if user2 send an email to domain2, postfix should be send using mail.server2.org with sasl. If users, sends mail to other domain, postfix should be send using classical smtp without authentication. Is there a howto or help for me? thanks! Pol

saslpasswd2 (and auth)
Hi all :-) I configurated a postfix with sasl authentication. saslpasswd2 -c -u `postconf -h myhostname` test0 testsaslauthd -u test0 -p test0 0: NO "authentication failed" Try with: saslpasswd2 -c test1 testsaslauthd -u test1 -p test1 0: OK "Success." sasldblistusers2 te...@domain1.org: userPassword te...@server2.domain1.org: userPassword So obviously, from client email smtp auth runs only with user0 and test0 (password) echo `postconf -h myhostname` domain1.org I don't understand what's the error... any idea? Thanks! Pol
blocks spam (hacked account)
Hi all :-) I read a lot but not enough... I need a something to block the spam when an account email has violated... so the spammer can use that account to relay spam emails to "the world" Are there postfix options to block this (or slowing down) or I need use third parts software? Need I work on iptables, fail2ban, psad and others? Thanks for help :-) Pol
Re: blocks spam (hacked account)
> Try: postfwd or policyd rate limiting. Sure! Thanks! A last question: real situation: sasl+tls user accounts. supposed situation: someone hack an account and take user+pass. That person do a script like this: i=0 while [ $i != 50 ]; do echo test | /usr/bin/mail -s "test message$i" "vic...@domain1.org" echo $i i=$(( $i + 1 )) done; with anvil I can only slow down the spam: anvil_rate_time_unit = 10s anvil_status_update_time = 120s smtpd_client_message_rate_limit=10 but if I modify the script that send an email spam every 5 minutes I can by-pass anvil rules :-( thanks for some advices Pol
sasl by sender
Hi all, I've finished to read sasl authentication and I can send email using it. Now I'd like that postfix send the email using the sasl username (te...@mydomain.com) and not with the sender of email client, because with 1 sasl authentication, every users can send with same sasl account, ie: us...@domain.org has a sasl authentication (ie: us...@domain.org) but also us...@domain.org can send using sasl authentication (us...@domain.org) and recipient receives different sender name. I need filter for the sender of email client. Any idea? thanks! Pol

virtual domains and aliases

how force sasl from localhost
Hi folks, I already read about sasl, postfix and other docs. External sasl authentication works, I need force users to authentication from localhost (i.e. CMS joomla and wordpress). inside main.cf: before: mynetworks = 127.0.0.0/8, 192.168.1.0/24 after #mynetworks = 127.0.0.0/8, 192.168.1.0/24 smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_sasl_security_options = noanonymous commenting "mynetworks" does not work, so, also explicit put: smtpd_recipient_restrictions = check_policy_service inet:127.0.0.1:10031 #permit_mynetworks, #permit_inet_interfaces, [...] or also substitute permit_mynetworks with reject_mynetworks, users can sends email from localhost what's wrong? thanks Pol

defer problem
I'm not sure if anyone use policyd (postfix cluebringer) but I can't solve a noise problem. policyd put limits to a number of emails, so reading this post from policyd: http://lists.policyd.org/pipermail/users_lists.policyd.org/2013-December/004283.html "I think You want postfix to accept all mail and delay sending it out. As far as i know this is possible in dual instance mode of postfix First instance accepts everything ino its queue and sends to second instance wich is configured to use policyd to limit mail traffic First instance sends messages when second instances policyd kicks in it stops accepting mail and replies with 450 4.7.1 this causes first instance of postfix to move the message to deferred queue." So, how can I configure postfix to accept all emails? thanks for help Pol
