[vchkpw] relay in vpopmail 5.4.6
I have compiled vpopmail 5.4.6 with mysql support. the configure says: tcpserver file = /home/vpopmail/etc/tcp.smtp open_smtp file = /home/vpopmail/etc/open-smtp the relay table is stored in mysql how can i use the -x option or other option to open relay. i am using --enable-roaming-users=y option. thank you.

[vchkpw] Silly Qmail (Queue) Syndrome and Spamcontrol Patch
Dear Erwin, Sorry for question not really related to Vpopmail. It seems that I am hit by Silly Qmail (Queue) Syndrome. I am using the Spamcontrol Patch v2.2.12 along with vpopmail-5.4.6, but have not used the experimental bigtodo. Wished to apply the bigtodo. I would like to get clarified that whether you bigtodo is based on ext_todo patch or big-todo patch or both. I had not initially compiled the bigtodo thinking that it is experimental. What do you suggest. Thanks. Devendra Singh

Apart from the big-todo enhencement, my implementation of Andre Oppermann's performance enhancements dont work well. After investigation a look of time and testing I didn't find any significant performance improvement. Note: The code in SPAMCONTROL is not the ext-big-todo; however it is based of Andre's first suggestion to influence qmail's scheduler for mail processing; which was buggy by itself. Third. The best thing is to avoid bounces to non-existing accounts. Use my RECIPIENTS extension as part of Qmail or perhaps the real-rcptto patch. The forthcoming SPAMCONTROL version will include verion 0.42 of the RECIPIENTS extension; check my Qmail page (http://www.fehcom.de/qmail.html). regards. --eh.

Re: [vchkpw] maildrop+vpopmail help required
Tanmaya Anand scribbled the following on 9/7/2004 11:00 AM: Hi All, I have netqmail+vpopmail+courier+sqwebmail. This is working fine. I have installed spamassassin maildrop, but unable to get it working. Can anyone tell me contents of maildroprc and other relevent info to get it working. Thanks in advance, Tanmay Hi- This doesn't help you with precisely your question, but *procmailrc* works very nicely on many systems. Here's a resource that might help you with that setup http://beret.net/vpopmail_procmail.php And while you're at it, which part of the SA/maildrop isn't working? You might try google.com and search, or... look into archives for Spamassassin and/or maildrop for more specific help. Rick

[vchkpw] vpopmail/qmail doublebounce issue
First time poster Have mercy on the neophyte! Can anyone point me to the right documentation source for properly configuring vpopmail+qmail so that doublebounces don't hang in the queue? My son had been managing this system, but got too busy, so I have to come up to speed just as Comcast decided that all the SPAM bouncing back out of our system was SPAM originating from our system, and quit allowing us to relay through their server. Originally, to mollify the ISPs that refuse mail from floating IPs, we had smtproutes set thusly: :SMTP.Comcast.Net Fine, until they got tired of processing the SPAM bounces. So, I peeled smtproutes back to: AOL.Com:SMTP.Comcast.Net ...so that at least the AOL mail from us would get delivered. Our server hosts several very small domains: TS5.Com, TS4.Com, and Christy9.Com. The system ME is mail.ts5.com. I noticed after removing Comcast as the relay that the queue began filling with doublebounces, addressed to [EMAIL PROTECTED], and the log indicated tons of entries like this: @400041372d553b41077c new msg 3794941 @400041372d553b410b64 info msg 3794941: bytes 11149 from [EMAIL PROTECTED] qp 13481 uid 507 @400041372d5601445164 starting delivery 81338: msg 3794941 to remote [EMAIL PROTECTED] @400041372d5601446cbc status: local 0/10 remote 2/20 @400041372d560fc141ac delivery 81338: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/ @400041372d560fc160ec status: local 0/10 remote 1/20 @400041372d580f829a9c starting delivery 81339: msg 3794751 to remote [EMAIL PROTECTED] @400041372d580f82b5f4 status: local 0/10 remote 2/20 @400041372d581900bfcc delivery 81339: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/ @400041372d581900db24 status: local 0/10 remote 1/20 @ So, vpopmail knows that ts5.com is a local domain, but when the doublebounce is generated, it is treating [EMAIL PROTECTED] as a remote address. Am I reading that right? (below: I have redacted the name of the relay server we are using, not because it is in any way an open relay -- it isn't, we run it, too -- but because the customer wants to remain private) I temporarily worked around the problem by adding first the entry TS5.Com:SMTP.*.Net to smtproutes: no effect. Then I added mail.TS5.Com:SMTP.*.Net, and the queue began to empty, but sent all the doublebounces to the default account [EMAIL PROTECTED] instead of to postmaster. Obviously I don't understand all the flow here, but would sure appreciate it if someone could point me to (1) the right documentation to cover this, and (2) an appropriate patch to vpopmail+qmail to avoid such heavy SPAM issues, like a SMTP-time bounce that works with vpopmail, or other technique that works more effectively than receiving all the bad mail, then generating bounce messages for them. 'Cause I know sending doublebounces out to another qmail server, and back again, ain't the way it should be done!

I am attaching Queue Size graph (5 Minute Average) updated Tuesday, 7 September 2004 at 0:50 (EDT). You can notice between 0400 - 1000 hrs (EDT) a quite high Mail Queue. During that time period the smtpd is running to the tune of 100/100. But the send is running to the tune of local 3/15 remote 5/40. The messages in queue but not yet preprocessed goes on increasing in wild. When the smtpd runs to the tune of 85/100 its all okay. This has started happening on almost every start of the week, when huge volume of genuine + virus infected customers mails start pouring in. I am not using RECIPIENTS extension, but using badrcptto for whitelisting mechanism, which works very well (might be a bit slow due to the reason that lookup is being done into txt database). I am also using http://linux.voyager.hr/ucspi-tcp/tcpserver-limits-2004-07-25.diff patch to limit concurrent connection from single IP. This helps identifying Virus trodden computers and denying them connection (it's a boon). I also have Caching-DNS on this Server (djbdns). About the todo patches the comments of Dave Sill (of Qmail Handbook fame) are interesting to note in the thread: Outbound email rate slows when inbound rate is high http://groups.google.com/groups?hl=enlr=ie=UTF-8c2coff=1threadm=e6c47de7.0310091325.147cade4%40posting.google.comrnum=2prev=/groups%3Fq%3Dext-todo%26hl%3Den%26lr%3D%26ie%3DUTF-8%26c2coff%3D1%26selm%3De6c47de7.0310091325.147cade4%2540posting.google.com%26rnum%3D2 Also one can have a look at the thread ext-todo and big-todo patches http://groups.google.com/groups?hl=enlr=ie=UTF-8c2coff=1threadm=wx0lm56pfo0.fsf%40sws5.ctd.ornl.govrnum=1prev=/groups%3Fhl%3Den%26lr%3D%26ie%3DUTF-8%26c2coff%3D1%26q%3Ddave%2Bsill%2Bext-todo%2Band%2Bbig-todo I tried to apply the patch http://www.nrg4u.com/qmail/ext_todo-20030105.patch over and above spamcontrol but it failed at: patch p1 ext_todo-20030105.patch patching file p1 patching file EXTTODO-INFO patching file FILES patching file Makefile Hunk #2 succeeded at 713 (offset 8 lines).
