Hi, I am relatively new to postfix but have worked with many mail systems over the years and am quite familiar with various flavours of Unix/Linux. My problem is as follows:
I have a Centos 6.5 system running Plesk V12 on which I have selected Postfix as the mailing system - let’s call this Server A. All my hosted domains work correctly and users can send/receive mail from clients and the webmail no problem - so far so good! I also have a standalone web application that uses Tomcat on port 8080 and part of that application sends out e-mails. Within the application I can set up the smtp host, smtp port, from address, auth and SSL details and these are configured to point to Server A using the e-mail details of one of the domains hosted on Server A. If I install this application on Server B then everything works exactly as expected with no issues and mails are sent to both internal and external addresses without issue. However if I now install the application on server A then the e-mails are no longer sent and I get an error message logged in the maillog that says (anonymised): Sep 30 01:04:14 mailhost postfix/smtpd[4721]: E861121C9A: reject: RCPT from mailhost.elysiumwebservices.com[DDD.DDD.DD.DDD]: 550 5.1.1 <undefined>: Recipient address rejected: User unknown in virtual alias table; from=<nore...@hosteddomain.com> to=<undefined> proto=ESMTP helo=<mailhost.elysiumwebservices.com> I have tried to debug the issue and have come to the conclusion (rightly or wrongly!) that it is something to do with the address rewriting and the To address is being replaced with nothing but when the mail is submitted to the server the To address is definitely there and valid. I have switched on verbose logging for the trivial-rewrite process and when I send an e-mail from nore...@hosteddomain.com to aaaaaa...@gmail.com I see the following output: Sep 30 01:04:14 mailhost postfix/smtpd[4721]: connect from mailhost.elysiumwebservices.com[DDD.DDD.DD.DDD] Sep 30 01:04:14 mailhost postfix/trivial-rewrite[4724]: name_mask: all Sep 30 01:04:14 mailhost postfix/trivial-rewrite[4724]: inet_addr_local: configured 2 IPv4 addresses Sep 30 01:04:14 mailhost postfix/trivial-rewrite[4724]: inet_addr_local: configured 3 IPv6 addresses Sep 30 01:04:14 mailhost postfix/trivial-rewrite[4724]: process generation: 40 (40) Sep 30 01:04:14 mailhost postfix/trivial-rewrite[4724]: Compiled against Berkeley DB: 4.7.25?
