Re: Grepping for emails problem.
A relatively easy solution might be to break the grep appart and not use regular expressions for the second component: grepmail -h '^Message-[Ii][Dd]' | grep -F "$MSGID" Michael

No, that doesn't work. What "grepmail" does is search inside a mailbox archive in mbox format with possibly many thousands of emails, and produce a target mailbox with only a few selected mails. And I use it to obtain the full single email contained in the archive that has a certain Message-ID. Thus, the first command above would hit every email, and the second would only produce a line, which is not what's wanted. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)

Just a thought. Couldn't you convert the mbox to maildir and process every single mail as a file? And if you need to go back to mbox from maildir just convert your grepped mail back to mbox. This way you don't have to rely on grepmails shortcomings. -- /bengan

Thanks, but the job is already processed :-) -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
