To investigate, send mail periodically from a cron job to a local account, look in the mailbox for actual deliveries, and then compare with the mail logfile for missing records. Wietse
multiple IPs and postscreen
Hi, I've gotten postfix working with multiple IPs/domains/ssl certs, and so far so good. I used the accepted answer at this link as a template: http://serverfault.com/questions/650057/postfix-multiple-ip-smtp-banner It works fine, until I try to add postscreen into the mix. So the setup is, in master.cf, first a clause for the local server: 127.0.0.1:smtp inet n-n -- smtpd -o syslog_name=postfix-localhost -o smtp_helo_name=localhost -o smtp_bind_address=127.0.0.1 -o myhostname=localhost (I'm not actually sure if that's necessary.) Then, for each of my two IP addresses, a block of services like so: # for the domain blue.com 50.56.xxx.xxx:submission inet n - n - - smtpd -o smtpd_tls_key_file=/etc/ssl/private/blue.key -o smtpd_tls_cert_file=/etc/ssl/private/blue.pem 50.56.xxx.xxx:smtpd pass - - n - - smtpd -o smtpd_tls_key_file=/etc/ssl/private/blue.key -o smtpd_tls_cert_file=/etc/ssl/private/blue.pem 50.56.xxx.xxx:smtp inet n - n - - smtpd -o smtpd_tls_key_file=/etc/ssl/private/blue.key -o smtpd_tls_cert_file=/etc/ssl/private/blue.pem -o syslog_name=blue.com -o smtp_helo_name=mail.blue.com -o smtp_bind_address=50.56.xxx.xxx -o myhostname=mail.blue.com blue-out unix - - n - - smtp -o smtp_bind_address=50.56.xxx.xxx -o smtp_helo_name=mail.blue.com -o syslog_name=blue.com There's another like that for red.com. Then in sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transports sender_transports: @blue.com blue-out: @red.comred-out: This works great until I turn on postscreen: 50.56.xxx.xxx:smtp inet n - n - 1 postscreen Now, I send myself an email, and in the logs see: blue.com/postscreen[6578]: warning: cannot connect to service private/smtpd: Connection refused I really don't know where to go from here. I guess I suspect something to do with chroot'ing, which I don't really understand, but I don't know how to fix it. Any pointers much appreciated! Thanks, Eric

I > thought this There is a remote possibility that a hash: table rebuild race with incoming mail could cause a message to be returned as undeliverable. Normally postfix logs all returned mail, but your logging seems incomplete. Please see http://www.postfix.org/DATABASE_README.html#safe_db Note: while this potential problem is documented and real, speculation that this is what happened to your missing message is an unproven wild guess. Additional evidence might be found in your log in the form of a bounce message delivered by your postfix to the sender of the mail in question, or evidence of returned mail might be found on the originating server. -- Noel Jones

Save yourself headaches and use multiple postfix instances instead. http://www.postfix.org/MULTI_INSTANCE_README.html While it may be possible to get postscreen to support multiple domains inside a single postfix instance, it's very ugly, with complex master.cf gyrations. If you want to give it a shot anyway, start with looking at the master.cf and postscreen documentation, and the smtpd_service_name parameter. -- Noel Jones

Re: multiple IPs and postscreen
Eric Abrahamsen: It works fine, until I try to add postscreen into the mix. you did not post a complete config. but you may check your master.cf: master.cf without postscreen: smtp inet n - n - - smtpd master.cf with postscreen: smtp inet n - n - 1 postscreen smtpd pass - - n - - smtpd Andreas

This maybe off topic, but could somebody tell me what i am doing wrong?
We want to send alerts to our admin staff from some of our remote servers. All the servers are Debian based and supply, smtp, imaps, file sharing (webdav), calendar and address book capabilities. To send the alerts we have tried email and sms messaging. eMail works but can be slow depending upon the number and quailiy of hops needed to get from the server to the admin. We had thought of of simply using a cell phone modem for each server. However cellular service at some of the locations is unreliable (too far north). To get round this we are thinking of using the email to SMS services offered by our telcos. We think SMS might be "faster" and more reliable as all network traffic passes through out telcos/ISPs centres fairly soon after leaving us. So, why doesn't this work echo "message text \r" | /usr/bin/mail -s "Server xxx - Alert" -r r...@example.com 4165551...@txt.bell.ca If I run the above I get a test message with the subject and sender correct, but the message arrives with "this message was sent with attachments which were lost". If I send same data using a thunderbird, outlook ... it works perfectly. Looking in the various logs I cannot see any difference between the two message. Postfix seems to behave in exactly the same way all cases. Help! JohnA

That should say echo -e "message text \r" | Sorry about that

That worked like a charm. Noel had me worried for a second there, but it looks like most of the necessary gyrations I'd already gone through -- that last step with smtpd_service_name was very simple. Thanks to Benny also for the cleanups and pointers, I was fishing a bit for help like that. Thanks again to all, Eric
