There will likely be a line something like I'd say `fetchmail' is the offending program here :-) The description for it says: This is a full-featured, robust and very configurable POP3 / APOP / IMAP mail forwarder. It's designed to pick up mail from a mail server host and deliver it _just_as_though_it_had_arrived_on_your_ _client_machine_via_SMTP_.[underscores mine] Obviously, splitting mail breaks this promise. File a bug report. Either the program or the description has a bug. Personally, I'd blame `fetchmail' if it claims to be a mail-transport-agent. MTAs should not alter message content. That's like the mailman opening your mail. MTAs can do whatever they please with the headers, but they should stay clear of everything that follows the first empty line, i.e. a line with nothing preceding the CRLF. However, `fetchmail' provides a `popclient' and I'm not sure what these beasties are supposed and allowed to do. However, if I were to ask my dog to fetch the mail, I'd be upset if it got ripped into pieces ;-) Splitting messages is something I'd only entrust to my mail-reader. Now I wonder where I have my sendmail.cf file, I am using (the Debian standard) smail. Can't see nothing about procmail in /etc/smail, I wonder how my system knows that it should deliver mail with procmail. If I could add this option, I guess my problem would be solved. Try this debian:~# find /etc -name sendmail.cf and have a look the `find' manual page after that. I just grepped through `Contents-i386' and the only references to `sendmail.cf' came from the sendmail and fidogate packages (hamm). The relevant file for smail is /etc/smail/config. Also have a look at the `smail-config' man page.

Try inserting the `E' option in the flags part (the F= string). This will make sendmail turn each dangerous start-of-line From into a From, preventing programs further downstream from acting up.

Those buggy old email implementations shouldn't be around anymore :-) What is a buggy old email implemantation? Are you talking about fetchmail/procmail or the mail programm the sender is using? Most of the mails which are torn apart are on the various debian lists, just because of the high volume I guess. I have seen sometimes that a mail containing a From line is changed to From, who should change the mail ike this? fetchmail? procmail? Or the sun where the mail is delivered originally? When I read the mail on the sun (Im no longer filtering there) everything is ok, its only torn on the way from the sun to my debian machine. Ciao, Christian.
fetchmail/procmail tears mail apart
Hi, I have a little trouble with fetchmail (hamm, 4.3.9-1), procmail (hamm, 3.10.7-6) tearing mails apart. I think I tracked it down, when I fetch a mail containing a line with From in the text, procmail sorts everything before From in the correct folder, everything after From (the line with From is lost) ends up in my bulk folder. Is this a bug or a feature? Is there an easy solution to fix this, some commandline switch or config change for fetchmail or procmail? Ciao, Christian.

I think I tracked it down, when I fetch a mail containing a line with From in the text, It is a common phenomenon with mail system, tracing back to a design mistake in the first email implementations. It should only affect lines that begin with F, r, o, m, space. I'm not sure which part of the chain is supposed to escape those From's, but the -Y switch to procmail seems be connected with this. Try inserting (or removing it, if it's already there) that and see if it helps. -- Henning Makholm http://www.diku.dk/students/makholm
