I followed the Ubuntu 9.04 tutorial two different times now and I always get the Postfix, "Mail.example.com Loops back to myself" error so I was hoping for a little help. I've searched through all threads about this before posting, btw. I'm wondering if my MySQL transport table has the right values. Hostname = server1.example.com MX record points = mail.example.com I used 'mail.example.com' in all my configs (except where it reflected domain name, and I put in 'example.com') Should my transport table value be: source + destination example.com + server1.example.com (changed but not tested yet) example.com + mail.example.com (this does not work) If there's anything else I can check, I'd appreciate some help as I'd really like to get this working. Output of 'postconf -n' Mailog error:
mail.example.com is already in the mydestination line, so I don't know why you still see that error. Did you restart Postfix?
RE: Virtual Domains, Mail loops back to myself Yes, I restarted Postfix many times . I've tried a lot of different things and then undone them when they didn't work. This is really strange. I can't get any further. Is there any Postfix diags I can run that would tell me what's going on? Thanks, UNi
RE: Virtual Domains, Mail loops back to myself SOLVED For some reason this line in /etc/postfix/main.cf causes a mail loop for my system: #transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf I basically reinstalled Postfix, got things working, then worked backwards to find the culprit. -UNi Also, as someone else mentioned, SpamAssassin is not enabled by default in the tutorial. pico etc/default/spamassassin ** Move it to ON, 1
After days of searching around trying to figure out what was going on (i had the same issue), I finally came across this. It actually has to do with the transport table itself. You do not need to populate this table. Keep it empty on a fresh install. It only applies if you are sending the message elsewhere to have it delivered.
Nice this one helped me too. I followed this guide when I ran into the same problem: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu-9.10 When disabling the line: #transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf What am I actually disabling? the feature of having more than one domain?
I enabled the line again, and emptied the transport table instead. Does this confllict in anyway with the line in main.cf: relayhost = <here I have my isp smtp>
