Re: lda and lmtp error after upgrading dovecot

29 Apr 2015


      Hello everybody,
I forgot to add a complete transaction sample of local delivery.
The following log depicts a mail delivery with two recipients; 10.1.1.1
is the last hop MTA server that calls lmtp for local delivery; the first
recipient got a correct uid while the second gets a "uid=error"; both
mails got delivered to INBOX correctly....
Thankyou in advance
Best regards
Giorgio

Hello everybody,
after upgrading dovecot on a debian wheezy installation from the
standard package version (dovecot 2.1.7) to dovecot 2.2.13-11 from
wheezy-backports, i noticed some errors in my logs...
Apr 28 22:00:13 lmtp(4879, xxxxxxxxx@unipd.it): Info: copy from <lmtp
DATA>: box=INBOX, uid=error,
msgid=20150428200011.47D801F32@mydoom.unipd.it, size=1523
They are not frequent but still coninuing since the upgrade.
After the upgrade I found also errors coming fom lda:
Apr 28 12:29:36 lda(userxxxxxx@unipd.it): Info: copy from stdin:
box=INBOX, uid=error, msgid=, size=595
Apr 28 12:29:37 lda(userxxxxxx@unipd.it): Info: msgid=unspecified: saved
mail to INBOX
Strange thing as I use lmtp for local delivery.
Is there some tuning I can do? My storage is accessed via NFS with a
load blancer keeping sticky sessions "per user".
Is there any risk to loose mails?
Here is my dovecot -n
Thanks in advance.
Best regards
Giorgio
