<HotaruT> hi, I've got a problem WC1VSURMOiAxMTAzNjM1Mjg2LjI2NTUNClgtTW96aWxsYS1TdGF0dXM6IDAw
<HotaruT> MDUNClgtTW96aWxsYS1TdGF0dXMyOiAxNDAwMDAwMA0KUmV0dXJuLVBhdGg6
<HotaruT> oops..
<HotaruT> hi, I've got a problem with message/rfc822 and transfer-encoding base64 (which is "EXPRESSLY FORBIDDEN" by RFC2045). sendmail deletes the first line of base64-data of such an mime-entity (or replaces with an empty line sometimes)
<pasteling> "HotaruT" at 84.166.214.225 pasted "problem with message/rfc822 and transfer-encoding base64" (9 lines, 283B) at http://sial.org/pbot/15885
<Squintz> Can anyone help me get my outgoing mail working?
<Zerberus> what does "route" say?
<gecjr> if have just come across a relaying problem, and was wondering if it may be fixed in a later sendmail release
<gecjr> in 8.12.10 it seems; that if the rcpt to uses a local name that relaying is allowed.
<gecjr> is there away to not allow this default behavior? by macro or is this something possibly fixed in newer version of sendmail?
<HotaruT> gecjr: hm? what is "relaying to a local name"?
<gecjr> no. if you connect to a server, and say your are sending to a local name. you can then also say I want to send to name@remote.domain; and the relaying is allowed!
<Zerberus> gecjr: it is the job of an MTA to accept mail for local delivery
<Squintz> sorry i was afk
<HotaruT> ah. I understand now..
<gecjr> is there away to require it to have a domain portion with sendmail ;to avoid this loop hole that is being used for spamming?
<Squintz> http://pastebin.ca/41780
<Squintz> I also did an nslookup but dont really understand the results well enough
<Squintz> http://pastebin.ca/41781
<HotaruT> Squintz: you have 2 default routes.
<Zerberus> gecjr: frankly i don't understand what you take as a problem
<Squintz> Okay
<HotaruT> Zerberus: as I understand, it is RCPT To: <postmaster> followed by RCPT To: <some@else.com> .. is this it gecjr?
<gecjr> zerberus: if you can connect to a server, and guess a name and then send off the server to everybody it is just as bad as an open relay
<gecjr> yes.
<Zerberus> gecjr: then you heavily misconfigured sendmail
<Zerberus> this is no default behaviour
<gecjr> so if you know a valid user name, you can enter other rcpt to send off the server. it seems that a vaild user allows relay without any further checking.
<Zerberus> misconfiguration
<gecjr> well; I'm using general config. I don't believe I did anything to change such handling from the default sendmail config. I would like to try on another sendmail server than my own to confirm the issue.
<gecjr> most servers I do personal mail through don't use sendmail ;so I just have the servers the problem is occuring on to test with.
<Zerberus> no no
<Zerberus> my sendmail just behaves as it should
<Zerberus> ... Relaying denied. Proper authentication required.
<HotaruT> I do not get this with neither 8.11.6+Sun/8.11.6 nor 8.13.4/8.13.4/Debian-3 ..
<Zerberus> for the foreign address, after a ... Recipient ok for the local user
<HotaruT> afaik the rcpt to: statements are independant of each other..
<Zerberus> it is no default behaviour
<gecjr> hmmm.
<gecjr> i have found a server, and agree with you.
<Zerberus> which OS?
<gecjr> wonder how the configuration got broken.
<Zerberus> show your sendmail.mc
<gecjr> linux redhat 7.1 using sendmail 8.12.10
<Zerberus> 111111!!!!
<Zerberus> awful!"
<gecjr> what that i'm using such an old version of redhat :-)
<Zerberus> 7.1 is dead like ages!
<Zerberus> no security updates since 3 years
<Squintz> Could this be my problem?
<Squintz> dnl # Uncomment and edit the following line if your outgoing mail needs to
<Squintz> dnl # be sent out through an external mail server:
<Squintz> dnl #
<Squintz> dnl define(`SMART_HOST',`mail.smarterior.com')
<Zerberus> 8.12.10 is not a sendmail release RH 7.1 shipped with
<HotaruT> Squintz: you have two default routes
<Zerberus> 7.1 had 8.11
<HotaruT> Squintz: this is your problem... unless you can explain me why it is not
<gecjr> yep. I have updated a few times.
<Squintz> Which do i get rid of and how?
<Zerberus> Squintz: route del
<HotaruT> Squintz: hm
<HotaruT> Squintz: wait a moment.
<gecjr> let me see if I can find the original mc file; I use a "template" cf file for the server configurations... I know probably bad thing to do.
<HotaruT> Squintz: do you have local access to this server? .. remotely modifing the routing-table is just bound to drop your own access too (o:
<Squintz> No but I can call godaddy and ask them to do it if it needs to be done.
<Squintz> I just need to know what to tell them to do.
<HotaruT> Squintz: hmm.. what is "venet0"? .. is this a linux box?
<Zerberus> vserver
<HotaruT> and.. default gateway "191.255.255.1" is strange too.. this adress is "IANA Special Use" (rfc3330) .. no one should be using it..
<weenie> hi
<Squintz> Hi
<Squintz> Okay, weenie is telling me he does not this it is the defualt routes because i can resolve names
<weenie> well you were able to, from the command line, nslookup various names - including your own.
<weenie> what was the exact error you get? and what are you doing to generate it?
<Zerberus> Squintz: mtr gsmtp183.google.com
<Zerberus> does that work?
<Squintz> command not found
<Zerberus> rpm -q mtr
<Zerberus> if not installed, then "yum install mtr"
<weenie> what does mtr do? not familiar with that util.
<Squintz> i just install it
<gecjr> Zerberus: http://pastebin.ca/41784 is probably the mc used. Maybe I should try to rebuild one from scratch and see if the problem is fixed.
<HotaruT> weenie: matts traceroute..
<Squintz> http://pastebin.ca/41785
<Squintz> looks like it worked to me
<Zerberus> sendmail -bt -d0.13 < /dev/null
<HotaruT> ok.. and does "telnet gsmtp183.google.com 25" work?
<Squintz> http://pastebin.ca/41786
<Squintz> [root@Xena root]# telnet gsmtp183.google.com 25
<Squintz> Trying 64.233.183.27...
<Squintz> telnet: connect to address 64.233.183.27: No route to host
<Squintz> yup
<HotaruT> Squintz: can you send mail anywhere non-locally?
<Zerberus> possibly
<HotaruT> try "tcpdump icmp" in parallel to telnet .. if that is possible on a vserver..
<Squintz> is in parrallel the same as saying piping? If not how do i do this?
<weenie> squintz: if you cut and pasted that telnet command - the command was wrong - that 64.x.x.x address is yours right?
<Zerberus> mail.smarterior.com has address 68.178.205.138
<Squintz> correct Zerb
<Squintz> I did cut and paste his command
<HotaruT> Squintz: run tcpdump in the background or use a second terminal..
<Squintz> k
<weenie> squintz - so someone suggested you attempt to connect to port 25 on your own system there... I guess. you could do: telnet localhost 25 to see if the daemon is listening...
<weenie> I was thinking he needed to check config scripts... but maybe someone already helped him use a known good cf file?
<Squintz> i paste it
<Squintz> ill
<weenie> squintz: for what it is worth - i just finished comparing two mc files that I have on my system - one was for "local host only" mail and the other was a "normal" mail server
<weenie> squintz: the "local host only" has a bunch of Daemon_options near the top (they both do actually) - but the local host only config file has 127.0.0.1 for some of the inet options - where the "normal one" has 0.0.0.0
<Squintz> http://pastebin.ca/41788
<Zerberus> ooooOOO
<Squintz> ?
<Zerberus> who told you to place the masquerading settings at top of the .mc?
<Squintz> that tutorial
<Zerberus> which?
<Squintz> http://www.siliconvalleyccie.com/linux-hn/sendmail.htm
<Zerberus> no, it does not tell you that
<Squintz> whats it tell me then?
<Zerberus> make those settings near the end of the .mc
<Squintz> k
<weenie> squintz: I'm just suggesting you take a look at your .mc file
<Zerberus> where the fedora default already has entries
<Zerberus> echo '/map host gsmtp183.google.com.' | sendmail -bt -d8.8
<Squintz> [root@Xena root]# echo '/map host gsmtp183.google.com.' | sendmail -bt -d8.8
<Squintz> ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
<Squintz> Enter <ruleset> <address>
<Squintz> > map_lookup: host (gsmtp183.google.com.) dns_getcanonname(gsmtp183.google.com., trymx=1)
<Squintz> dns_getcanonname: trying gsmtp183.google.com. (A)
<Squintz> YES
<Squintz> dns_getcanonname: gsmtp183.google.com
<Squintz> returns gsmtp183.google.com. (0)
<Squintz> > [root@Xena root]#
<weenie> squintz !! also - that is your .mc you posted hu? there is a typo in it
<Squintz> ohhh? where?
<weenie> squintz:: second masquerade line - localhos.localdomain
<weenie> woops - not second
<weenie> last
<weenie> should be localhosT.localdomain no?
<Squintz> fixed it
<Squintz> Still not working though
<weenie> you fixed it and already did a sig hup?
<Squintz> even after moving things towards the bottom and fixing that spelling mistake
<Squintz> yes
<Squintz> I have a script
<Squintz> #!/bin/bash
<Squintz> cd /etc/mail
<Squintz> make
<Squintz> newaliases
<Squintz> /etc/init.d/sendmail restart
<Squintz> thats the proper way correct?
Return to
