(i don't have vc compiler here) Francis === Message d'origine - 10/02/2013 22:45:09 === Hi On my servers, I noticed increasing number of failed deliveries with 417 Temporary delivery error and Error connecting to remote address. I did a little investigation and long story short, XMail doesn't handle address family fallback, when connection using preferred one does not succeed. It simply tries only one address per MX and if it doesn't work, it considers that MX dead and moves to another one. Now imagine what happens when you use -M7 parameter (use IPV6 records if present, or IPV4 records otherwise, for host name lookups), target system has both IPv4 and IPv6 records set for all MXes (soon to be standard for most servers, well perhaps not so soon, but it's getting more and more common) and IPv6 is broken on either side or anywhere between. XMail tries connecting using only IPv6 for a while, until it finally gives up and returns the message as undeliverable. Which is wrong, because if it tried IPv4, it would deliver it just fine. Relatively safe workaround for now, assuming IPv6 as a new thing is going to break more often than IPv4, is to use -M5 instead (Use IPV4 records if present, or IPV6 records otherwise, for host name lookups). But it means that IPv6 won't get used at all, except for few rare IPv6-only MXes. Also the problem does not really go away, if it happens that IPv6 works while IPv4 does not, it will be back. Attached is patch with works for me solution, i.e. not tested by anyone else nor even necessarily correct. It makes XMail try to connect to all addresses of MX before moving to next one. Apart from possible unintentional errors, it deliberately ignores -M5 and -M7 parameters and uses AF_UNSPEC for getaddrinfo() and all results when one of them is set. It respects -M4 and -M6 if someone really wants to use only one address family. IMHO -M5 and -M7 are wrong, at least on Windows, where getaddrinfo() with AF_UNSPEC returns addresses in best order automatically and manual override should not be needed. I think Linux either does that too or at least has means to influence it using /etc/gai.conf. So even if -M5 and -M7 should stay as useful for someone, adding new -M8 for AF_UNSPEC order would be good idea. PSYNC has the same problem. And I guess CtrlClnt connecting to server probably too, but it's far from critical. -- ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
Re: [xmail] DbgFix: Mail loop detected
Hello The MaxMTAOps variable have nothing to do with 'dns' name resolution mechanism so dns name resolution problems will 'normaly' not be resolved increasing this parameter (except bug in xmail, but I don't think, dns code is very isolated from mails process in xmail code).. If you have a 'Mail loop detected', even you can have two sort of reasons : - Real loop : some server in the route resend the mail to one of the previously used smtp servers (or itself) in the 'route' to the last, and your server is one that receive again and again the message (it detect loops regarding smtp headers counting the Received: lines). Nothing to do here on your xmail server to correct this problem, the mail is in a loop, increasing MaxMTAOps will not correct the 'loop' Very likely some chain of forwarding accounts that send to others forwarding accounts, that ... and another forwarding account 'forwarding' back in the chain, in this case find the 'back forwarder' and correct the forward will be the only solution To know if this is the problem, try capture the mail reaching your server again in again (see logs, ... use a filter) and verify the Received: headers chain to see a loop - In normal situation on the Internet it's rare to reach the default 16 'MaxMTAOps', even with big ISP having many servers (front ends, avscan, spam scan, , backends, forwarders, final clients servers, ... if each task in a different server). But if you suspect this is the problem ^(and not a real loop) try increasing by steps (say by 4 step, 20, 24, ...) until the 'loop' detection stops (if you reach more than 32, I think its a Real Loop you detected) Regards Francis -Message d'origine- De : xmail-boun...@xmailserver.org [mailto:xmail-boun...@xmailserver.org] De la part de David Lord Envoyé : mardi 16 octobre 2012 18:15 À : U.Mutlu Cc : xmail@xmailserver.org Objet : Re: [xmail] DbgFix: Mail loop detected On 12 Oct 2012 at 16:54, U.Mutlu wrote: Just wanted to share a debug session to trace down a Mail loop detected situation: A bounce mail with reason Mail loop detected is generated under this circumstance: if it takes too many steps (operations) to get the first MX record (or the final A record when MX is missing after trying all) of the recipient domain than what is defined in server.tab under MaxMTAOps 16 I had problems with some mailing lists and over a period gradually increased MaxMTAOps to 28.

I do think XMail does move files between those folders, which isn't the same as copying a file and then deleting the original file. If both folders are on the same partition, moving a file doesn't require actually copying its contents, it simply is linked to a different location. If you're moving a file from one partition to an other, this however does result in making a copy and then deleting the original. So if most mails on your mailserver end up in a mailbox, then it would be better to have spool and domains folder on the same partition. In the light of this: I would be interested to know when XMail moves files and when it makes a copy. I have for example read that setting the temp-folder in memory would be a good thing to do. But if files are moved in and out of the temp folder instead of being copied there, this might not be such a good idea. Does anybody have an insight on this?

Re: [xmail] smtp authentication configuration
Simple to do :) First you only need to use smtpauth.tab file if you need to auth non xmail mailbox users (that don't have a account in xmail), as xmail will firstly lookup in mailusers.tab for xmail users credentials To force Auth on xmail external listening ip add this line in server.tab file SmtpConfig-aa.bb.cc.dd,25 MailAuth After this, any connection to aa.bb.cc.dd will force auth (or rejet if none is done at start of smtp session) - aa.bb.cc.dd is your external xmail ip - eventualy replace 25 (after comma) with your smtp port if different - eventualy add more lines if using others ports ie : SmtpConfig-aa.bb.cc.dd,587MailAuth (for port 587) - to bee sure xmail only listen to thoses ips (including localhost) on multihomed server (multiple ips on interfaces), configure xmail to listen only to 127.0.0.1 and aa.bb.cc.dd (with multiple cmdline parameters -SI ie : -SI 127.0.0.1:25 -SI aa.bb.cc.dd:25 -SI aa.bb.cc.dd:587 ...)

Re: [xmail] Knowing who is failing Auth Logins
Rob, I don't know if wireshark can decode, but depending of the LOGIN method attempted : AUTH PLAIN method In this case the login and password are just encoded (not encrypted) in Base64 in the next client packet after the server 334 response AUTH LOGIN method Again login and password ar just encoded in Base64 but send in two sequences (first 334 server, then client send login, then server send 334 then client send passord) In these to cases I think you could easily find on the net a Base64 'decoder' (probably a web page with a javascipt form doing the decode) :) if AUTH CRAM-MD5, it is more complicated, because it use a 'challenge' (encoded in base64), then MD5 encryption with the password as the key on the challenge More explanations here for these AUTH methods :http://www.samlogic.net/articles/smtp-commands-reference-auth.htm Expecting the 'client' use PLAIN or LOGIN to help you quickly :) Regards Francis -Message d'origine- De : xmail-boun...@xmailserver.org [mailto:xmail-boun...@xmailserver.org]De la part de Rob Arends Envoye : mercredi 19 janvier 2011 15:13 A : 'XMail Users Mailing List' Objet : Re: [xmail] Knowing who is failing Auth Logins Hi Francis, I had a look at the tcpdump, and I can see the LOGIN command, but the data is encoded.

I think this is a major bug :( It's not violating the standard, but in the interests of robustness, I agree that it is a problem. See: http://tools.ietf.org/html/rfc5321#section-5 Another peculiar XMail behaviour is that even if the hostname in an MX record is unknown, XMail logs an error but then tries again. This only makes sense if the recipient fixes his MX records, which I think is more likely if the mail is permanently failed rather than temporarily. In Postfix, it's user-configurable which method is used. Again, no violation of the spec, but my preference is for a behaviour that is somewhat more robust, especially today with spam-filled queues everywhere. Note that if the remote domain would properly implement RR DNS, the issue would not arise, as the IP list would be permuted at every lookup. Of course, people does RR DNS with TTL of one day, which kinda defeats the purpose. XMail could do its own random-pickup in the supplied list, but this is really not its own task. This was exactly the case here, RR DNS worked (see my previous response) Francis ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail

Could this be a sort of 'timeout' between xmail and the smartdns server ? (if so could this 'timeout' be changed ?) ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail

GLST is a life saver on my side. It cuts a lot of SPAM and worms out there. I have to admit I do not keep my xnets updated very frequently though. - Davide Same usage for me And except some very rare exceptions (at this time only 3 xnet for some servers that seems to never retry) I never added xnet for hotmail and gmail (nor yahoo, ...), and seems to never miss mails from them due to glst. The only change I did for hotmail was set timeo to 30s as hotmail first retry is one minute from same sending server, to not delay too much.

Re: [xmail] building the source code
Perhabs you could give us some errors returned when compiling to help us find what is missing in your VS setup ? Notice that if you only want to run 'standard' xmail server on window you don't need to compile it, Davide create ready to use win binaries at each release, so simply download win binaries, install, setup and use :-) Francis -Message d'origine- De : xmail-boun...@xmailserver.org [mailto:xmail-boun...@xmailserver.org]de la part de GiGi Envoye : jeudi 3 juin 2010 16:49 A : 'XMail Users Mailing List' Objet : Re: [xmail] building the source code I build it in vstudio 2008, got the same errors, also, can u please specify me, exactly what .h and cpp association in what projects ?

Re: [xmail] is this maillist alive? need to configure xmail pop3retrieval
Two fetchmail like programms that run on win32 : mpop : http://mpop.sourceforge.net/ or mailfetcher 2 : http://mailfetcher.sourceforge.net/ Francis -Message d'origine- De : xmail-boun...@xmailserver.org [mailto:xmail-boun...@xmailserver.org]de la part de William Ottley Envoye : lundi 31 mai 2010 20:37 A : XMail Users Mailing List Objet : Re: [xmail] is this maillist alive? need to configure xmail pop3retrieval hmmm interesting! I saw that program actually, and then saw that it only saved via emails. so I'll read the documentation on how to use the sendmail function to convert it? and save it into the users mail box? to be honest, with this setup, xmail server will be running as a server for a single email address.. thanks for that heads up!

I'm also aware of a thread I read, where someone wanted the same thing as I did, and someone else offered for them to use fetchmail... but i can't use fetchmail on my windows system. so, I was hoping maybe someone figured out how to use xmail to have it always running, then maybe implementing a command line manual as well? but. as you have kindly (thank you) stated, this is not possible with xmail system, UNLESS I use the PSYNC... perhaps your aware of some other script? php maybe? or .exe that will grab emails and put into the mail folder for xmail? Lng time ago (could be 15 years since the last time I used it), I did this: http://www.xmailserver.org/GetMail-1.3.zip It fetches POP3 mail and saves them into .eml format. You could then use XMail's sendmail, to feed messages into the XMail LMAIL. But, you'd have to manually figure out which account messages will have to be fed into. - Davide ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
