    Of course you have to leave those ports open, because you cannot provide the services without them being open.

    port 80 is the most high risk port at the moment due to all kinds of web vulnerabilities, selinux could mitigate some of the attacks that can be launched via the web.

    How ever you have to be vigilant and proactive in updating your software.

    OK, still is up and running :)

    I have one more question, from Horde interface or from IMAP clients (outlook, etc) the SMTP function works fine...

    But if i setup a POP3/SMTP account on outlook/express when it tries to send a message, the receiver rejects me because in the main.log file of exim the user seems to login as [email protected]@mailsrv (mailsrv is the hostname...) from Horde the user seems to login as [email protected] what should i change to work this OK?

    Thanks in advance (one more time!)

    Setup your from address to the correct one (full email address) it seems like the server is trying to qualify your address.
  4. gsp

    gsp New Member

    Yes but this is the problem.. in outlook client the from address is set up correctly...

    And for some reason exim gets this 'double' id.. [email protected]@mailsrv


    Maybe if i use the qualify_domain in config of exim option?

    PS. this is what i get when trying to send from outlook:

    2008-12-03 11:48:45 no host name found for IP address
    2008-12-03 11:48:53 1L7oLd-0001hM-Lb <= "[email protected]"@mailsrv H=(sync4j) [] P=esmtpa A=login:[email protected] S=12046 [email protected]
    2008-12-03 11:48:54 1L7oLd-0001hM-Lb ** [email protected] R=dnslookup T=remote_smtp: SMTP error from remote mail server after RCPT TO:<[email protected]>: host []: 504 5.5.2 <[email protected]@mailsrv>: Sender address rejected: need fully-qualified address

    and THIS is what i get when i send the same test message on the SAME address..

    2008-12-03 10:59:50 no IP address found for host localhost (during SMTP connection from [])
    2008-12-03 10:59:51 1L7naI-0001Qs-JZ <= [email protected] H=(localhost) [] P=esmtp S=2230 [email protected]
    2008-12-03 10:59:52 1L7naI-0001Qs-JZ => [email protected] R=dnslookup T=remote_smtp []

    is qualify_domain set ? and are u using smtp authentication ?
  8. gsp

    gsp New Member

    Yes SMTP authentication is used.. (without this doesn't work at all)..

    Also if i set qualify_domain the message pass but in the receiver appears a crazy from like this

    From: "[email protected]"; on behalf of; test [[email protected]]

    Is there any way to avoid this and have just the sender's address?

    ALSO, do you know any guide/way on how to set-up more than one virtual domains?
  9. topdog

    add your networks to this
    hostlist   relay_from_hosts =
    Then relaying will work without authentication, it seems like there is an issue when you authenticate i do not know what it is as when i tested mine worked with no problem but i was using thunderbird so i do not know.

    Virtual hosting is so easy with this all you need do it add the domain to
    domainlist local_domains =
    and then add the user to the database.

    for example

    [email protected]
    [email protected]
    [email protected]

    Means you have 3 virtual domains domain1 domain2 and domain3
  10. gsp

    gsp New Member

    Ok so my thoughts were right. I will try this..

    In the meantime i tried the relay_from_hosts field but after set my network there, authentication is not needed and i get these in the logs..

    2008-12-03 13:25:05 no host name found for IP address
    2008-12-03 13:25:16 no host name found for IP address
    2008-12-03 13:25:18 unknown named domain list "+relay_domains"

    F****! every time something happens!!! :mad::D

    Post your config file.
  12. topdog

    Find the line
    domains = +local_domains : +relay_domains
    and change to
    domains = +local_domains : +relay_to_domains

    Thunderbird does exactly the same behavior...

    ok hosts corrected... but in the domain section existed one '!' .. is it needed?

    Now what ever address i put in To: it sas 'User uknown' (in the log file..)..

    :confused::confused::confused: i will break this box!!! :eek:

    I do not understand what u are saying, are u saying you cannot send mail anywhere ?
  17. gsp

    gsp New Member

    Yes that was correct... probably some typing mistake... now reverting back to my original conf, and fixing the hosts that you stated seems to work without authentication.

    I am wondering because thunderbird makes the same problem if i use authentication.. do you use it by the same way?(authenticated or not)?

  18. topdog

    topdog Active Member

    When i tested with authentication it worked for me with out altering the address. I do not work for the company where the production system is running anymore but i can test again on my dev virtual machine.
  19. gsp

    gsp New Member

    OK, if and whenever you have the time it would be good to know how to make this work...(compare our configs..) maybe some of my clients want to use outlook from 'outside' connections and the only way to keep my SMTP safe is to require authentication from all except localhost..

  20. topdog

    Can you email me with authentication on i want to see how the headers are being altered
