2 servers with postfix problems

[obey]

hi,
first of all, this is some kind of crossposting. I asked for help in the german corner before, so this is just a translated version of that post:

i got 2 postfix problems:

1. its about a centOS rhel5 server. after the difficult installation of rc4 i got an error at the webmailer, that the mail couldn't be sent, cause of the missing smtp service. i checked that and port 25 wasn't open. postfix wasn't even able to start. so i changed the daemon_directory and the program_directory in the main.cf. this helped at least to start the postfix service. if i tried to send a message over the webmailer it ran and loaded and loaded and loaded... and then said: message has not been sent. Without any further explanations. The error.log told me:

Code:

[Wed Jul 09 09:57:20 2008] [error] [client 127.0.0.1] script not found or unable to stat: /usr/lib/cgi-bin, referer: http://admin1.interfrog.de/client/webtools.php

so i read a post which said: use the packages from thatfleminggent, otherwise postfix will be broken. I downloaded and installed them, but now i'm not even able to log into the webmailer again:

Code:

ERROR: Connection dropped by IMAP server.

any ideas to get this running again?

my 2nd prob:
on a debian etch server the installation hasn't been such a pain in the a**, everything works fine, except sending mails over a client. webmail works, mails get delievered locally and remote....only the client asks me again and again for my password. The mail.log says:

Code:

I know there are a lot of posts with similar issues in the forum, but none of the solutions worked.
at least the

Quote:authentication failure: no secret in database

seems kind of strange. if you need any configs or more informations, plz feel free to contact me.

i would appreciate any idea or any help.

greets obey!
