hiho all !
i am planning to set up my own email server, i read several howtos and man
pages but there are still some things which are not
clear to me.
first let me describe what i want to do :
1) i want to fetch email from various pop3 servers
2) spam-filter them
3) scan their attachments for viruses
4) transfer them to my windows client behind my gateway (where all this
should take place)
ad 1)
as far as i know for this to be done one needs the programm "fetchmail".
now i have some questions regarding this:
a) why in the world does fetchmail want to send the emails it got from the
pop servers via sendmail and local port 25 ?
i want them to stay on the gateway in the users directory, and i dont
want them to be sent elsewhere ...
b) i saw that one can create .fetchmailrc files to "poll" email in certain
periods of time.
but what if i want to fetch my email via my windows client NOW and not
next time cron starts fetchmail ?
is there a way to have fetchmail "see" that it should fetch mail NOW ?
ad 2) i know that i can use procmail for this and what i first want to do is :
filter all spam mails with certain words in their subject.
now what i did so far is, creating a procmailrc file that
contains following entry
:0
* <word to trigger filter here>
/dev/null
now there are lots of words which occur in spam mail and instead of writing
such an entry for each of them---is it possible to to an "OR" expression in
the * section ?
just to list all words there and say : if this word occurs OR if this word
occurs OR........-> /dev/null
ad 3) where do i have to call the email virus scan programm - > in the
procmailrc file ?.....a filter that matches ALL emails and then as an
action scan them for mails ?......which expression DOES match ALL incoming
mails ?
4) i use ipop3d on the gateway to get the mails in my users mailfolder on
my windows client.
now if i telnet to port 110 of my gateway i get following after
entering the correct user/pass:
-ERR Unable to open user's INBOX
what can cause this ?.....
i know the emails are there because if i check my /var/spool/mail/user file
they are all there......
and last but not least, can anybody recomment good tutorials/guides/how-tos
or other sources that cover these topics ?
thx for your efforts,
