After Install: Mail not working and FTP strange

Hello,

Today I installed ISPconfig on a new Server (Debian Sarge Basic Image, then "Perfect Install" from HowTo)
I kept the given Hostname (IP.provider.tld) and installation worked well

But after starting ISPconfig. I noticed, that in the Services overview FTP-Server was offline. Restarting didn't change anything and trying to restart on the shell returned:

proftpd restart
- warning: "ProFTPD" address/port (xx.xx.xx.xx:21) already in use by "Debian"


I ignored that and pre-configured my domains (9 Clients), which are currently still running on my old server.

Then I switched one of them (including MX) to the new server (www.mydomain.tld is working OK) an created an user (web7p1)
Maildir has been created and I can access the Mailbox with Outlook Express and Uebimail. But trying to send mail with either of them results with an error:

Code:

Feb  2 18:40:34 xx-xx-xx-xx courierpop3login: LOGIN, user=web7p1, ip=[::ffff:xx.xx.xx.xx]
Feb  2 18:40:35 xx-xx-xx-xx courierpop3login: LOGOUT, user=web7p1, ip=[::ffff:xx.xx.xx.xx], top=0, retr=0, time=1

Feb  2 18:45:45 xx-xx-xx-xx postfix/smtpd[2226]: warning: myip[xx.xx.xx.xx]: SASL LOGIN authentication failed

On the other hand, connecting to the server with an FTP client works fine (despite of the first error)

If you can help me get my mail working and explain the ftp behaviour I would be glad

 

Well I added "SocketBindTight on" to proftpd.conf and rebooted, but that changed nothing: The message now reads:

proftpd stop
- warning: "ProFTPD" address/port (xx.xx.xx.xx:21) already in use by "FTP-Servername"
- SocketBindTight in effect, ignoring DefaultServer

and the FTP-Server-Status in ISPconfig is still "offline".

The FTP-Server is reachable by the configured user. Unfortunately the user is not restricted to his Web but able to browse the whole server.


Even worse is, that I'm still unable to send mail.

 

Please post your /etc/proftpd.conf here.

It seems as if saslauthd isn't running. Please run

Code:

/etc/init.d/saslauthd start

 

saslauthd is running (restarted it to be sure) but still sending is not possible. This is what uebimail tells me:

It was not possible to send this e-mail
SMTP Error: Recipient not accepted. Verify your relay rules

SocketBindTight on

Include /etc/proftpd_ispconfig.conf

 

smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination

mynetworks = 127.0.0.0/8

Could reject_unauth_destination be the problem?

 

Thx for the help so far.

Unfortunately I have to reset the server and reinstall everything. If I run again in this problem, I will return here. For now, the problem is "solved"

Thank you anyway.

 

Hi, I am having the same problem.

When setting up postfix for plain text authentication (eventually to use TLS) I try to use telnet and verify that it is setup correctly. Unfortuneatly it seem to always fail authentication. I think it might be due to not knowing how to authenticate. What should be in /etc/pam.d/smtpd ?

Further details (and my config files) can be found @ http://marsianman.is-a-geek.com:8000/wp

Any help would be appreciated, thanks guys.

 

It seems as if saslauthd isn't running. Please post the output of

Code:

ps aux

Also, on your page I read this:

You don't need sasldb2 because you're using saslauthd which means your user must be in /etc/passwd and /etc/shadow and have a valid password.

 

So here I am again

I'm sorry but the problems consist (at least partially)

Status:
Mail receiving OK
Mail sending OK with Outlook Express
Mail sending fails with Uebimail
(Error: It was not possible to send this e-mail
SMTP Error: Recipient not accepted. Verify your relay rules)

Mail log says:

Edit: Added "check_relay_domain" as said here
http://www.howtoforge.com/forums/showthread.php?t=323&highlight=Webmail+send+error
and reloaded postfix but that did not help



Proftp still "offline"
Access with FTP-Client seems to be OK (User is confined to his folders)
Access with Web-FTP fails (Error: Could not connect to localhost)

proftpd.conf:

 

Did you restart Postfix after your changes?

Please post the output of

Code:

netstat -tap

 

Yes, I restarted postfix, and the mail.log still says the same as quoted above

netstat:

I guess the value of mynetworks is not correct in /etc/postfix/main.cf because otherwise you should be able to send from localhost (Uebimiau). Please post /etc/postfix/main.cf here.

Code:

is correct...
Please run

Code:

postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,check_relay_domains'

and restart Postfix.

 

Success!! Sending with Webmail now works.

The necessary change to main.cf was not only to add "check_relay_domains" (which I already tried before) but to delete also "reject_unauth_destination"

That's really great, thank you for your help.

 

And what about FTP-Server: Offilne?
I have the same problem...
