postfix issues

[whitty]

For a while during my tweaking/learning phase of installation, I couldn't get email to work at all, then I hammered out the issue and got it working 100% but another one popped up and my solution broke postfix again, and now I can't get postfix to recieve incoming mail anymore. Through some trial-and error analysis and log/config snooping, i've figured out that everything is perfect, but during the phase when i COULD send AND recieve email, the server hello line was the hostname of my server instead of its reverse dns entry (note, not the hostname which was being used for mail, a different one that always resolved). This should help: http://pingability.com/zoneinfo.jsp?...ittyhost.us.to Very helpful for domain troubleshooting. I've tried everything I can think of, making sure absolutely every dns entry is super clean and the like, making sure the users are set up, and when it still wouldnt work I looked at the postfix log in /var/log/maillog. What I saw was odd. Hopefully you can help me figure it out (note my current email account on the server is admin.@.whittyhost.us.to, other entries in the log are gmail resending faild emails from a while ago, and galexyalex.@.gmail.com (minus the dots) is the email it's sending from.

Thanks for the help, let me know if you need anything else in the way of configs/logs!

Please post your postfix main.cf. If it is too long, you can attach it as .txt file.

What is in your /etc/hostname file?

Please make sure your ISP doesn't block port 25.

[whitty]

maybe that's the problem - nothing in hostname i'll play with that, hadn't noticed. Thanks! In case not, here's main.cf

and no, port 25 is fine since mail worked in the past. My ISP is great besides the slowish speed, they don't block/shape/filter anything whatsoever (besides maybe a 5 IP cap that I haven't hit yet)and I doubt you could do anything to get banned short of maybe trippling your bandwidth with an uncapped modem or something.

EDIT: Nope, adding the right host did take care of the using rdns in the hello line and such, but it didn't change the behavior, i still get that same log pattern above.

You should add myorigin, myhostname and mydomain entries in main.cf and restart Postfix.

YAY thanks a bunch, never would have figured it out. I figured ispconfig did stuff like that automatically. Here's another one: the default email address for a user is always user@www.domain.tld instead of user@domain.tld, despite an entry in codomains with no hostname, just domain.tld, allowing mail to be sent to user@domain.tld just fine. This is also new since the system worked last. Is there any way to change that without the user adding their own identity in the mail program?

[falko]

If you have domain.tld on the Co-domains tab, you automatically have the email addresses user@domain.tld and user@www.domain.tld.

[whitty]

right, but when i log into the webmail app with webX_user, the default address it uses is user@www.domain.tld. Is there any way to change that to user@domain.tld

[falko]

You can change that in the webmail settings. Every user has to configure his email address in the webmail settings, just as you do in any normal email client.

[whitty]

hmm, not quite sure we're on the same page: when i set up an email user for a site "domain.tld", i have no option but to set it up with what it tells me is user@domain.tld. I then log into webmail with webx_user or user@domain.tld (Both work) and the default email address that email is sent from for that user is user@www.domain.tld. It used to be that when i logged in (when i first had email working this is) i would default to sending email from user@domain.tld and not have to set up an alias, which would be far more convienient. Is there any way to replicate that without needing to set up the alias manually?
