[fetchmail-users] fetchmail on server unable to connect to postfix

[M. F. <mfi...@ne...>]

Hello,

I have on my home computer the working fetchmail rc file shown below, to
download all the messages from my ISP pop3 server to my home box.

Now I want to reuse that file on a Centos server, separate from my home
desktop, running postfix, dovecot and fetchmail-6.2.5-6.0.1.el4

On that server there is no user "marco". There are only virtual email
users, and I'd rather not add other Unix users there. On the server there
is ad-hoc user without shell which is only used by postfix and dovecot to
deliver messages to mailboxes:

# grep mail_only_account /etc/passwd:

mail_only_account:x:2000:2000::/home/mail_only_account:/bin/false

However, if I run as user mail_only_account:

/usr/bin/fetchmail -vv  -f /usr/local/etc/Fetchmail/always

fetchmail always gets from postfix:

Helo command rejected: need fully-qualified hostname

no matter what I write in place of "marco": root, this complete address
mfi...@ne..., whatever.

More in detail:

fetchmail: SMTP< 220 the.server.com ESMTP Postfix
fetchmail: SMTP> EHLO localhost
fetchmail: SMTP< 250-the.server.com
fetchmail: SMTP< 250-PIPELINING
fetchmail: SMTP< 250-SIZE 10240000
fetchmail: SMTP< 250-ETRN
fetchmail: SMTP< 250-STARTTLS
fetchmail: SMTP< 250-ENHANCEDSTATUSCODES
fetchmail: SMTP< 250-8BITMIME
fetchmail: SMTP< 250 DSN
fetchmail: forwarding to localhost
fetchmail: SMTP> MAIL FROM:<test_address> BODY=8BITMIME SIZE=1471
fetchmail: SMTP< 250 2.1.0 Ok
fetchmail: SMTP> RCPT TO:<mfi...@ne...>
fetchmail: SMTP< 504 5.5.2 <localhost>: Helo command rejected: need
fully-qualified hostname

Why does the rc file which works fine at home fail on the server?
OK, if I understand correctly, the problem is that _postfix_ is
configured differently, and it's not a fetchmail problem. However, I am
not sure if I can (ask to) change the postfix configuration right now, so
I'd be very grateful if somebody could let me know if there is any
possibility to "patch" it by passing some other option to fetchmail.

Alternatively, pointers to the specific postfix setting causing this are
also welcome.

Thank you in advance for any feedback,
           Marco

Please upgrade to 6.3.8

So, fix your postfix configuration :)  You may find that setting the
fetchmail keyword smtpaddress to something that is qualified will help
(see the man page).

Correct, this is a postfix configuration issue.

Having taken 2 seconds to consult the postfix documentation:

http://www.seaglass.com/postfix/faq.html#dapp

Provides details as to the setting that causes this.  I suspect you
actually want to further consult the postfix documentation to
whitelist localhost from that test.

[fetchmail-users] Solution (??) of: fetchmail on server unable to connect to postfix

[M. F. <mfi...@ne...>]

Hello everybody.

please accept my apologies for screwed threading, or if I have missed
some of the most recent answers and you need to repeat something to me.

As you may have noticed by now :-) I am moving from one email server to
another these days and is not being painles...

This is the situation now. I have found a newer rpm which installed
without problems on Centos 4.4:

rpm -q fetchmail
fetchmail-6.3.4-1.1_6.el4.at

this one works! with the /etc/hosts and fetchmailrc files shown below.
It may be helpful for the next guy if this difference in HELO behavior is
documented somewhere, since I happened into it by using the default
packages provided with my chosen distro.

Thanks to Rob and all the others who helped me and thanks in advance
for any answer to this last question: is there anything in the
setup below which is redundant or, worst, may cause any security problem?
