+ Delimiter and Shared Folders

[Matthias Busch]

Hey,

the + delimiter (address+something at domain.tld) works fine for users, but 
seems to be broken with shared folders.

Is there a way to get that working with editing postfix/cyrus config files?

Best case scenario would enable the + delimiter to sort the mail in the 
right folder in the shared folder.

If that is not feasable, I really would like for those mails not to get 
lost...

Which it seems is the case:

Nov  6 12:23:30 mail postfix/smtp[28882]: 26D3BB80A08: 
to=<shared+shared/address at domain.tld+something@domain.tld>, 
orig_to=<address+something at domain.tld>, 
relay=127.0.0.1[127.0.0.1]:10026, delay=0.09, delays=0.07/0.02/0/0, 
dsn=2.0.0, status=sent (250 OK Message 
/var/spool/pykolab/wallace/tmp8ubTKU queued)
Nov  6 12:23:30 mail postfix/qmgr[8074]: 26D3BB80A08: removed
Nov  6 12:23:30 mail postfix/smtpd[28883]: connect from localhost[127.0.0.1]
Nov  6 12:23:30 mail postfix/smtpd[28883]: warning: Illegal address 
syntax from localhost[127.0.0.1] in RCPT command: 
<"shared+shared/address at domain.tld+test"@domain.tld>
Nov  6 12:23:30 mail postfix/smtpd[28883]: lost connection after RSET 
from localhost[127.0.0.1]
Nov  6 12:23:30 mail postfix/smtpd[28883]: disconnect from 
localhost[127.0.0.1]

The sender wont get notified of the failure. And the mail does not 
appear in the shared folder...

Any ideas?

Thanks in advance!
