[Dovecot] No 'from' in messages

[Remy Zandwijk]

Hi all,

Over the weekend, we've migrated our old mail environment to Sendmail and
Dovecot:

	- Dovecot 1.0 stable
	- Sendmail 8.13.3
	- Procmail 3.22

Procmail is MDA for Sendmail and it delivers mail to Maildir boxes. Email 
clients
like Eudora, Thunderbird, Outlook and mutt are working OK. When using Outlook
Express and Pine however, in the message list the 'from' or 'sender' field 
is empty.
This means users of these programs cannot see who did send the mail to them.

When running Dovecot 0.99 in a early test period, this problem did not occur.

Question: Did anyone see this behaviour before and how to fix it?


Best regards,
Remy Zandwijk
