I have a domain which its fqdn is mail.robin.com pointing to this i have added a subdomain rep.robin.com the mx record has been set up with isp for rep.robin.com also rep.robin.com has been added to the mydestination line in main.cf in postfix and to hosts file in /etc/hosts what i have done is set up postfix to accept mail to '[email protected]' and deliver them via pipe to the command "repserver -d foo" its the "deliver them via pipe to the command repserver -d foo" than i do not know how to set up.? but my thinking is: in /etc/aliases someusername: | repserver.pl(path to it) run newaliases no need to run repserver.pl -d $someusername because script gets called automattically? (repserver is a perl script) rob
Should work. Did you test it? Alternatively you can put your pipe into a .forward file in the user's homedir. the .forward file must be owned by that user.
perl script+postfix did i test it? no not yet. the script it i were to print it out on paper would use 30 A4 size pages!! it will create a data base so people can create email addresses and use them at rep.robin.com can you please give me an example of how the command might look if i were to use a .foward file in say username rob's homedir? something like this in say rob's homedir echo '"| /path/to/repserver.pl"' >>~/.forward? the comand so that rob has ownership is what ,chmod rob rob .foward? robin
Yes. .forward is executed as the user to whom the directory belongs (it's the user's homedir), so there's no need to specify a user.
yes thats correct it is there but inside the file .forward we have: "|/usr/bin/procmail -f-" is it still ok to issue the comand below? echo '"| /path/to/repserver.pl"' >>~/.forward OK i looks fine but I need to rethink first option was: /etc/aliases someusername: | repserver.pl someusername (and newalias) second option was: "|/path/to/repserver.pl someuser in the .forward. I must remember the repserver script is able to add new users when they complete the registration process, so I would have to modify the script in order to run one of these two commands after a successful registration. This is messy. I'm quite sure there is a cleaner way to ask postfix to pipe every mails received for ${foo}@${nymdomain} to "repserver.pl -d $foo".? robin
You will then lose your procmail recipes, i.e., they won't be executed anymore, so I guess it's better to go the /etc/aliases way.
yes i would like to do you suggested but if you read the paragrapth in my last post which reads: in the .forward. I must remember the repserver script is able to add new users when they complete the registration process, so I would have to modify the script in order to run one of these two commands after a successful registration. This is messy. I'm quite sure there is a cleaner way to ask postfix to pipe every mails received for ${foo}@${nymdomain} to "repserver.pl -d $foo".? two commands means i cannot use .forward or /etc/aliases robin ps how about use procmail like this: | repserver.pl $LOGNAME but not sure in which file to place this command after what you said in post 6?
postfix/script create a filter, maybe. I have a perhaps simpler idea but i am not sure how to set it up perhaps you could point me in the direction by way of howto's or other information. here we go: Make rep.robin.net a virtual alias domain, with a wildcard. Point that virtual alias to some local user ([email protected] or whatever). Have *that* user deliver to a pipe, via /etc/aliases. or another way to say the same thing: in some local domain on that server, add an alias for a user, say, "repserver", that pipes to the program. Then add rep.robin.net as a virtual alias domain, and add a wildcard virtual alias that points to repserver@thatlocaldomain. robin
>Hm, I think a Postfix filter is easier to implement... ok thanks falko please point me to a howo or some info that might help please. ok i think we have to two things? 1 define a content_filter parameter for the proper smtpd in the master.cf file 2 Define the tranport in the master.cf file. here is my master.cf it does not come out like the one i pasted but i think it will be ok ------------------------------------------------------------------------------------------------------------------------------------------- # # Postfix master process configuration file.

Have a look here: http://www.postfix.org/FILTER_README.html http://www.advosys.ca/papers/postfix-filtering.html
thanks for the url's please indicate which paragraph's in readme below are specific to creating a filter in /etc/postfixmaster.cf for my script. are we concerned with the simple filter setup? http://www.postfix.org/FILTER_README.html robin
postfix/filter how does this look: -------------------------------------------------------------- in /etc/postfix/main.cf relay_domians = rep.robin.net etc/postfix/master.cf repserver unix - n n - - pipe flags=FR user=repserver argv=/home/repserver/repserv -d $recipient ------------------------------------------------------------------------------------------------- (a) paste above line into main.cf and two lines at bottom of master.cf file? (b ) create a user with adduser called repserver make a directory mkdir: repserver and with touch a file called repserv and i assume place the actual perl script reserver.pl in the repserver directory? (c ) In master.cf there is a line see below or post 11(does this affect the relay_domains line in main.cf)? relay unix - - - - - smtp -o fallback_relay= robin
I post an example how I once configured a simple filter in Postfix. In master.cf, I changed the first line to Code: smtp inet n - y - - smtpd -o content_filter=filter:dummy and then at the end of master.cf, I created the filter called filter: Code: filter unix - n n - - pipe flags=Rq user=filter argv=/usr/local/anomy/filter.sh -f ${sender} -- ${recipient}
postfix/perl script ok thanks for your post falko(see pm) ok i think i know what to put at the end of master.cf now it will be ( filter is called repserver) repserver unix - n n - - pipe flags=FR user=repserver argv=/home/repserver/repserv -d $recipient (this line above should be on one line like your little box in the last post but i think you get the idea) so we have the bottom part of the master.cf I am not sure what the top part would look like?
thanks for making this content_filter clear Just to put things into some sort of order TODO: place the the line in /etc/postfix/main.cf relay_domains = rep.robin.net place the lines in /etc/postfix/master.cf top smtp inet n - y - - smtpd -o content_filter=repserver:dummy (why dummy)? bottom repserver unix - n n - - pipe flags=FR user=repserver argv=/home/repserver/repserv -d $recipient finish? THINGS NOT TO DO create a user with adduser called repserver make a directory mkdir: repserver and with touch a file called repserv and i assume place the actual perl script reserver.pl in the repserver directory In master.cf there is a line see below or post 11(does this affect the relay_domains line in main.cf)? relay unix - - - - - smtp -o fallback_relay= robin
