Need some help getting tmomail.net MMS messages into my qmail
server. Gmail.com has
apparently overcome the "invalid sender" issues which are blocked by
chkuser. Mail to
earthlink.net also succeeds.
My qmail / vpopmail: vpopmail-toaster-5.4.13-1.3.3 Uses chkuser: v.
2.0.8 for vpopmail > 5.3.x
Email server blocks MMS email from tmomail.net
e.g. # grep -i 'invalid sender address format' Log | tai64nlocal
Log /var/log/qmail/[EMAIL PROTECTED]
Produces "invalid sender address format" for the TMOMAIL MMS email..
2007-05-28 21:31:54.930953500 CHKUSER rejected sender: from \
<1805nnnnnnn/[EMAIL PROTECTED]::> remote
<mailx06.tmomail.net:unknown:66.94.9.236> \
I get the same thing when a user I have tries to send using his Tmobile
phone. Whats happening is the / in the username; what chkuser is seeing is
"1805nnnnnnn/[EMAIL PROTECTED]" as the username. It doesn't like the
slash. You can recompile chkuser to accept these, if you don't mind
opening a security risk like that (actually, I'm not 100% positive you can
allow a / or not...).
Coincidentally, I just had this same issue come up. According to RFC
2822, a forward slash apparently is a valid character in an address -
http://www.zvon.org/tmRFC/RFC2822/Output/chapter3.html#dot-atom.
Am I reading this wrong?
In the Chkuser documentation,
http://www.interazioni.it/opensource/chkuser/documentation/chkuser_settings.html#MX_format_checking
there is apparently an environment variable you can set called
"CHKUSER_ALLOW_SENDER_CHAR_xxx" where you can tell it to allow certain
characters, but a "/" isn't one of them.
Did the original poster ever come up with a solution other than
recompiling Chkuser?
