'+'-Zeichen in Mailadresse erzeugt einen neuen Ordner im Imap und wird zugestellt

Andreas-2
Hallo,

ich stelle ein Verhalten bei Postfix fest, dass mich irritiert.
Wenn ich Mails erhalte, die im Namensteil vor dem at-Zeichen ein '+'-Zeichen
einhält, wie nachfolgend an "[hidden email]", dann wird die Mail
angenommen und nicht verworfen. Stattdessen erzeugt Dovecot einen neuen Ordner
namens "test", dem Teil der nach dem + folgt.

Du hast das Handling von geplusten Adressen ja sowohl in Postfix
(recipient_delimiter) als auch in Dovecot (lmtp_save_to_detail_mailbox,
recipient_delimiter) aktiviert.

Am einfachsten ist es, lmtp_save_to_detail_mailbox in Dovecot zu
deaktvieren.

Stefan

Ich habe inzwischen in der master.cf den Eintrag

dovecot         unix    -       n       n       -       -       pipe
       flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f $
{sender} -d ${user}@${nexthop} -e

und in der /etc/dovecot/conf.d/90-sieve.conf das Plugin

recipient_delimiter = +
aktiviert. Nach einem Neustart beider Services erzeugen Mailadressen wie
[hidden email], [hidden email]
immer noch Ordner im Maildir des Benutzers wie "facebook" und "tester", in
denen diese Mails dann landen.

Was vermutlich nicht viel ändert, solange Du das gar nicht benutzt,
sondern die Mails per LMTP an dovecot weiterreichst - zumindest deutet
folgendes darauf hin:

Ich rate mal:
lda_mailbox_autocreate = yes
?

Hallo,

 

ich habe

lmtp_save_to_detail_mailbox = no (20-lmtp.conf)
recipient_delimiter = + (90-sieve.conf)
recipient_delimiter = + (main.cf)
lda_mailbox_autocreate = no (15-lda.conf)

gesetzt. Allerdings landen die geplusten Mails nach wie vor in eigen generierten Ordnern.

 

Grüße

 

Andreas
