RE: Qmail and RFC1894 - Delivery Status Notifications
I am somewhat hesitant to rely upon VERP's because I have seen several problems in how some email programs handle the = sign in the VERP. We all know that the = sign is a valid character for the local part of an email address according to the RFC, but there are many mail programs (definitely some clients, but how MTA's handle VERP's is unknown to me) which incorrect parse the = sign. The incorrect parsing results in something that looks like: list-action-username=userhost@listhost being interpreted as: userhost@listhost Has anyone else found problems with VERP's? I know that I have experienced several problems with mailto: and reply links when using ezmlm. Some clients that I know have problems are Yahoo, Excite, etc. In the short term, I have modified my bounce processor to parse DSN's and qmail bounce reports. Thoughts? Thanks.

QMail doesn't support DSN (unless there's a patch, you have looked at www.qmail.org, right?). Check out VERPs -- Variable Envelope Return Paths. Searching google should provide some good hits.

badmailto functionality ?
All- Is there a way to block the delivery of messages through my smtp servers to particular addresses? I have qmail acting as a local relay sending mail from inside my network to users on the outside. The users that I want to block would be on the outside, but the mail is sent from the inside. I can use the badmailfrom control file to block mail from someone, but I am looking to block mail to a list of people. As always, thanks for the help. James
Qmail and RFC1894 - Delivery Status Notifications
All- I have a need to process mail server bounces in an automated fashion and planned to make use of RFC1894 - An Extensible Message Format for Delivery Status Notifications. This appears to be used by most of the public mail servers that I have tested against, but when a mail bounces out of one of my local qmail machines (e.g., cannot connect after the maximum queue time), the message that I am receiving back from qmail does not appear to follow the RFC specification for reporting this error. Do I have something mis-configured? Is there a patch to bounce using RFC1894 standards? Thanks for the help. James

Duplicate Messages and missing trailers.....
Has anyone ever had the problem where messages are delivered more than once? On what appears to be random occasions, messages are delivered twice to my lists. I did notice this at one point happening to the qmail and ezmlm lists. Also on random occasions, messages distributed to my lists do not appear to have the designated trailer included in the messages. Again, no real pattern to this one either. I am running the latest version of qmail and ezmlm/ezmlm-idx on Redhat 6.2 with double confirmation disabled (I am doing the double-opt in elsewhere). Thanks for the help. James
Possible bug in qmailanalog matchup program?
All- I am attempting to process about 500 MB of qmail log files but continue to run into the following bug when running the matchup program: matchup: fatal: unable to write fd 5: file descriptor not open I have isolated the problem to the matchup program by running the following sequence of commands: # cat /var/log/qmail/*.s /var/log/qmail/current biglog.txt # cat biglog.txt | /usr/local/qmailanalog/bin/tai64nfrac big64nfrac.txt # cat big64nfrac.txt | /usr/local/qmailanalog/bin/matchup bigmatchup.txt I get the above error on the last line of this sequence of commands. I also get the same error if I string all of these commands together into a single line such as: # cat /var/log/qmail/*.s /var/log/qmail/current | /usr/local/qmailanalog/bin/tai64nfrac | /usr/local/qmailanalog/bin/matchup bigmatchup.txt Without being able to process all the data, I am afraid that I cannot extract the information I desire using the other qmailanalog tools. Thanks for the help. James
Converting dates from seconds since epoch to readable dates
All- I am attempting to write a script which examines the qmail logs files for statistics on ezmlm mail lists. In order to make sense of the results I need a script or command which will turn the dates that come out of qmailanalog's matchup program into human readable form. Does anyone have a script or know the command to turn a date such as 973212991.884939500 to a real date that you and I can easily understand? Thanks. James
RE: Converting dates from seconds since epoch to readable dates
Mr. Zajkowski- The dates that come our of matchup are not tai64n formatted. However, I was provided with following perl script by another list member which appears to do the job: #!/usr/bin/perl -n # chop; s/^[^0-9][^:]+://; ($time,$therest) = split(/\s+/,$_,2); print scalar localtime($time)," $therest\n"; Thanks.
