[xmail] Connection timeout with vmware
Hi I'm using xmail on a Linux Ubuntu in a vmware machine on Windows XP. That's just for trying out but should still work fine. It usually works well but sometimes a POP3 or SMTP connection from the mail client is not closed immediately. I can see it in the debug output that POP3 client connection from... is written and the corresponding POP3 client exit comes like a minute later. And during this time of course I can't make another POP as the mailbox is locked (I think). So I get client errors like connection aborted due to timeout or other failure or connection refused. The client in such a case returns immediately, for him the connection is closed. Now I don't know if this is a problem with xmail (probably not), with Linux, with vmware, with Windows or even something else. I just wanted to ask if anybody has seen errors like these or might know what could go wrong. Is anybody using xmail in a vmware machine? Anything else I should look out for? The mail client is on the same PC, so in the Windows that also hosts the vmware machine. Network latency shouldn't be a problem then, but maybe something else?

[xmail] Re: Bounced eMail messags
Hello All... Recently a SPAMer started sending eMails to the server using a dictionary for eMail addresses like [EMAIL PROTECTED], [EMAIL PROTECTED], etc. Then the eMail Servers trys to send an eMail message back to the sender indicating the eMail was NOT delivered because of a bad eMail address. So I've set NoSenderBounce to 1. By changing this setting will this stop this behavior? Next, I still need SenderBounce enabled for certain eMail accounts. I was wondering why we don't push down a lot of these configuration options to the domain level like SmarterMail does? If a lot of folks using xMail are ISP / ASP then this would make sense to have management control at the domain level. I don't know if you guys have seen this but the SPAMers are now using your eMail Server, if eMail bounce back Messages are on, to effectively SYN Flood someone. The way this works is they get hold of some domain then point that domain's A to an IP that does NOT have an eMail Server associated with it. Typically, these domains don't have MX records. Then, they send a slow drip of eMails to the same domain, the effect is the eMail Server tries to deliver the bounce back to the sender over and over again. Each time the bounce back is attempted an TCP connection is attempted and of course a SYN is generated first. Now, imagine, that you have several 100 eMails in the message queue, all the time, all trying to connect to that same IP at various intervals based upon the time they were received. And now you get a SYN Flood. How do we solve this? Can you simply ONLY send eMails to domains that have MX records? I know this Probally violates and RFC, however, we else can we do until someone decides to fix the larger SPAM issue.

[xmail] Re: Bounced eMail messags
Hi, Last weekend I had an example of this happen to one of my backup mail servers. When I noticed the problem there were 27,000 NDR type messages it was trying to deliver. Mostly all were sent to random [EMAIL PROTECTED] and the mail server was diligently trying sending NDR's to every single one of them - most likely to faked or spoofed addresses. I could actually sit and watch more junk flooding in, they appeared to be coming from many compromised hosts so blocking the IP's didn't really help. So it would be very useful if Xmail at least had an option so that it does not send all the bounced email messages. I realise this may not conform to the RFC's and I realise that not many people may use it, but it would still be a very helpful if the mail-admin found that NDR messages were getting out of hand. One or two legitimate senders may not know that their mail was not delivered, but when compared to the type of flood described here its a small price to pay Regards, Wolfy At 11:56 PM 3/10/2007, you wrote: Hello All...

One or two legitimate senders may not know that their mail was not delivered, but when compared to the type of flood described here its a small price to pay Yes, you are absolutely correct -- this is becoming a very SERIOUS problem. All of this started with us back in July. The problem comes and goes. [NB: NDR = ?] However, the issue now is I'm getting complaints from the folks getting the bounce backs because a lot of time the from line in header is forged and points to a real eMail Address. I'm also getting complaints from the targets of the effective SYN Flooding. What I started to do is test this work around idea -- create a bogon user for said domain and set the alias to a '*' then set the disk quota 1K. So this first captures all of the bogus eMails for a domain and once the quota reaches 1K an error should be sent back indicating the mailbox is full. The problem is that xMail still generates a bounce back eMail message ! Now, I'm not an SMTP RFC expert, however, if xMail would simply reply 452 Requested action not taken: insufficient system storage instead of accepting the eMail we would be fine. Let the sender deal with the error. If it was a legitimate sender the sender's MTA would send the bounce back to their user instead of us. As I understand it, if the sending MTA gets a 4XX Reply code, the response code is considered to be a transient Error and the sender's MTA is responsible for the queuing of the eMail and trying again. The middle digit in the 452 error code, in other words -- 5 indicates, the problem is with the destination MTA. If sure someone on the list knows this RFC stuff better and can offer another solution that is more RFC compatible. It think we need to get this NDR problem solved quick...

Francis Wrote @ Wednesday, October 03, 2007 10:37 AM Use glst (greylisting) :) Allmost 99% of these bad connexions will be elliminated, as 99% will = never retry. And as glst will first response with a 4xx code, no NDR until second = attempt connexion accepted by glst. That is a good idea... However, when I tried Greylisting before with a different eMail Server and I found some MTAs like Hotmail.com did not re-queue the eMail for a second attempt like they should -- of course I did not try this idea with xMail. I am C challenged -- anyone have Windows 2K3 binaries that I can try out? The only downside with this idea is that we still have to deliver the NDR at some point. I still think it is best we let the sending MTA handle the bad eMail destinations. Thanks, Hal Dell Managing Partner ePodWorks.net, Inc.

[xmail] Re: XMail resends old emails after reboot.
As my spool gets inundated with junk, I run this command every day at 11:30 p.m. via a cron job. find /var/MailRoot/spool -depth -name *.MX2 -ctime 1 -delete MX2 is the name of one of my xmail boxes so all files in the spool have it appended to the end of the filename by default. Works like a charm :) This actually looks at the current day plus 1 day so you'll always have files 2+ (but less than 3) days old in your spool. Checkout the man page on find to see the options for times (minutes, hours, etc...)

XMail tries to remove the spool file, and fails. File remains inside the spool (but not in the in-memory queue). Next time you restart XMail, it'll be picked up. - Davide - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

I have a stock V1.24 out of the box -- only filter installed is xbmf.c. Never heard about xbmf !?!? No link in xmailserver.org home page in available tools :/ I missed somethink usefull ? xbmf was developed to deal with the eMail tail null-byte issue and another liken brethren. The Windows OSen (maybe others) has / had a problem with their MIME parsing routines such that if an eMail has improper termination sequence or tail at then end of a particular email message being recevied via POP3 it can hang eMail client programs. Since, a lot of third party apps including Euroda use the Win API they hang as well. Therefore the purpose of xmbf was to filter out these eMail messages before they get into the user's eMailbox. 99.99% of the time any of these eMails that are NOT properly terminated are hacker eMail ! For windows search CheckPop3Tail -- this registry entry adds a check to MS POP3 Service.

[xmail] Re: XMail resends old emails after reboot.
My xmail servers are only pass through boxes for redundancy and virus scanning (and yes, my retry is 1 day so having a 2 day purge is perfect in my scenario). The only things that ever stay in my spool are ndr's back to spammers. Thanks!
