Check what is really in the message.  Some mail programs display the
null address in modified form.

This is valid: To: undisclosed recipients :;
This is not:   To: 

I hope Cyrus is complaining only about the latter.

When we migrated to Cyrus we wrote a preprocessor perl script that
rewrote certain header lines to make them standard.  The rewritten
mailbox was output to a staging area, and that's what we moved.  This
approach might work for you.

Re: Importing Mails without "to" header

[Michael Polenske]

Hi Joseph,

the worst information is that we have not really a possibility to change the 
mail that should be migrated. We do a migration from Lotus Notes, and because 
we were not able to find tools for migrations mails from Notes to Imap (imap 
on Notes is not switched on) we use a tool that convertes Lotes Data to 
Outlook .pst data, wich can me moved via a Outlook Client into our mailserver 
(in german we say "from behind through the eyes).

So if there is a possibility to tell cyrus to be more flexible I aprecciate 
all hints in this direction :)

Best regards,
Michael

Re: Importing Mails without "to" header

[Michael Menge]

Hi,

we had similar problems importing e-mails via IMAP from an old UW-IMAP System.
We found that the "to: undisclosed recipients" was not the problem,
but lines beginnig with ">From " or Headerlines with an linbreake.

We removed/repaired the corroup heades in the old Mailboxes
Telemitrie logging was very usefull to find the invalid headers in  
large mailboxes.




Quoting Michael Polenske <[EMAIL PROTECTED]>:



Hello,

we are in the middle of a migration of an old mailserver, and during
mailimport from old system we can see a problem.

Situation: an old user has a mail in his account, that was sent   
_only_ to bcc:

People, so in "to:" you will only find "". When we
now try to import these mails into a cyrus imap folder we get a message that
an invalid header was detected.

Any idea how to tell cyrus (2.2.12) to be less rigorous about such headers ?

Cheerio,
Michael
