Citadel Support

Tue May 15 2012 14:24:00 EDT from chuckf @ Uncensored Subject: Problem/possible bug? - Latest Citadel on Ubuntu 10.10 64-bit

I have a customer running citadel as their MTA.  They communicate on a regular basis with FedEx.  After applying the recent release via 'apt-get dist-upgrade' they have been having trouble getting email to fedex.

FedEx has 3 MX servers listed and the first, by design, always fails with 'Connection Refused'.  Each of the MX entries is mapped to multiple IP addresses rather than them having each and every IP listed as a separate MX.

For some reason the latest citadel will not go to the next MX in the list.  My workaround was to hardcode a fake entry into the local bind server to remap the first MX addresses to the secondary MX addresses.  I'm not really sure why this broke if it is because fedex.com's DNS is misconfigured (my guess) or if something is failing.  It seems as though once the 'Connection Refused' happens, citadel throws the message away without any error bounces and never tries the next MX.

 

Can anyone please advise?

 

Best,

Chuck

fixed; please upgrade. Thanks for reporting.

Hi,

Is there a way to block brute-force attacks on a citadel-server? I think
it does not log the ip-addresses of hosts who try to connect, so it
seems difficult with iptables/fail2ban. Acually I run citadel version
8.04, maybe this feature yet was realized in the newest version.
Someone does know?

Kind regards,
Henning

since 8.10:

        CON_syslog(LOG_WARNING, "Bad password specified for <%s> Service <%s> Port <%ld> Remote <%s / %s>\n",
               CCC->curr_user,
               CCC->ServiceName,
               CCC->tcp_port,
               CCC->cs_host,
               CCC->cs_addr);


//citserver[5610]: Bad password specified for <willi> Service <citadel-TCP> Remote <PotzBlitz / >
in case of smtp the address should be there.

smtp:

    syslog((LOG_MAIL | LOG_INFO),
        "%ld: from=<%s>, nrcpts=%d, relay=%s [%s], stat=%s",
        msgnum,
        sSMTP->from,
        sSMTP->number_of_recipients,
        CC->cs_host,
        CC->cs_addr,
        result
    );
where result can be

        if (msgnum > 0L) {
            sprintf(result, "250 Message accepted.\r\n");
        }
        else {
            sprintf(result, "550 Internal delivery error\r\n");
        }

    if (scan_errors > 0) {    /* We don't want this message! */

        if (msg->cm_fields['0'] == NULL) {
            msg->cm_fields['0'] = strdup("Message rejected by filter");
        }

        sprintf(result, "550 %s\r\n", msg->cm_fields['0']);

here could alternatively to 'Message rejected by filter' be the error message of the spam facility.

    }

so
stat=550

should be your trigger here.

CCC->cs_addr);


//citserver[5610]: Bad password specified for <willi> Service <citadel-TCP>
Remote <PotzBlitz / >

when you have some working rules, would you like to write a littel howto citadel <-> fail2ban?

I guess webcit didn't fill in the ip here already...

citadel-tcp is port 504.

Hey guys,

Any idea why my freshly-installed-from-debs Citadel server would work fine under firefox but "Not found" is displayed under Chrome?

Thanks

are you installing with an apache/nginx proxy?

Hello everybody

/etc/init.d/webcit start

i used the easyinstall , and i allready tried to reinstall

thank you for you help :-)

Hello Again

i solved it, it was some conflict with my wmware player !

sorry for my post

I'm not. Should I?

I need to use subaddressing / address tags for an application on my Server. Subaddressing or Address tags refers to the abiity to send email appended with extra info, eg if my email address is info@email.com, I can send mail to info-responder@email.com, or info+responder@email.com and the email will be accepted, with the address tag in place so that I can use it from an application.

Does anyone know if Virtualmin supports this functionality. I know Zimbra supports them but I have been looking at Citadel and VirtualMin, as I am using Webmin already. I can't find any info about support for address tags for either Citadel or Virtualmin.

TIA

I saw in Citanews that there was a new release.

The libcitadel-8.11.tar.gz file appears to missing from the actual source server...citadel-8.11.tar.gz and webcit-8.11.tar.gz are both there, but libcitadel results in a "not found".

if you mean something like http://www.everything-mdaemon.com/mdaemon/a-subaddressing-introduction , this is possible in citadel with a shared / public maileable room.

have a look at:

http://www.citadel.org/doku.php?id=faq:everydayuse:how_do_i_post_messages_via_smtp_mail_into_a_room#how.do.i.post.messages.via.smtp.mail.into.a.room

as you might have already noted, this is the citadel support forum, not the virtualmin forum. you will have to ask that question else where.
