Friends,





I find this in the wiki - ok , that sounds dead on


1.Is it generally agreed that "disabling the check for all incoming mail"

:allow,BADMIMETYPE="",SENDER_NOCHECK="1",BADLOADERTYPE="M",CHKUSER_RCPTLIMIT="50",CHKUSER_WRONGRCPTLIMIT="10",QMAILQUEUE="/var/qmail/bin/simscan"
 exactly how do I do that?

N.N.N.N:allow,RELAYCLIENT="",RBLSMTPD="",SENDER_NOCHECK="1"
where N.N.N.N is the blackberry mail server?
maybe 4 is my best solution... I so far- only have 1 complaint.

I have a blckberry user who has the complaint of 5.1.0 - Unknown address error 571-'sorry, sender address has invalid format (#5.7.1 - chkuser)' is a good solution? best solution? 2. are there any - risks downsides? 3. ( most importantly )if I wish to disabled the check for all incoming mail 4. do i have the option of editing my tcp.smtp and would I be correct in thing that it is as easy as

My 2 cents.

I wrote that wiki page, and then edited it later as a FYI. I went through all the trouble of turning off the checks for all of Blackberry's MX entries and unfortunately Blackberry has a couple "ghost" mail servers that are not listed in DNS. I had a screaming client during the process, so I would fix it and the next day he would get the above message. I'd find the ghost MX server and add it telling him it was fixed, and it happened again the next day with a new ghost machine. After a couple of what looked like "foot in mouth" moments with my client I threw my hands up and turn off sender checking for the whole machine. Those symbols are technically allowed by the RFC, and I could not really see how they could be used to exploit the system since they're not really translating to filenames or anything, so I do not see any reason to deny them. I have been allowing them for a couple months now and have had no adverse effects from it.
