Hi,
i am the new one;) - and my first post is about a problem i ran into.
I installed a mailserver on a RaspberryPi. It works mostly well, using
dovecot 2.1.7.
(exim4 4.8 (not in use, smtp direct to Provider), fetchmail 6.3.21,
RasPi 3.12.28+, Roundcube (no version known) - the whole system went
through an apg-get update/uppgrade this night to look if a known problem
already been fixed.
When getting bigger Attachments (not sure if it occurs by smaller too,
but bigger attachments are normally "to open" and often fail)
Not all of them, but much. Unpredictable when it occurs.
These Attachments are shown with less size in the Mailclient
(Thunderbird actual version). In Roundcube they are shown to small, too.
But it looks as the mail IS "fullsized" on the lokal Mailserver: When i
use Roundcube and try to open an x00kB .zip, Roundcube starts to get the
whole xyMB (real size) .zip-file, even when disconnected from internet.
Thunderbird behaves different, doesnt load the full file, so "ignore" is
no option;) And yes, i always dont like that option:)
Beside the lokal mailserver-account(s) there is/are pulled Mails via
imap direct from the mailprovider, the "old" solution which shall be
replaced by the new mailserver. imap direct from provider shows the
mails/Attachments in corrects size an opening works.
Only using the local mailserver fails.
In the log-files i found (i quote a part in which - cronjob matching -
one of these defect mails was pulled):
In Syslog:
Mar 26 09:40:01 raspberrypi /USR/SBIN/CRON[26696]: (info) CMD

(To tell the whole story: /home/$user/mail is link by NFS to a NAS. The
limit 0 and timeout entries are just to test after running into the
error and before i discovered that not fetchmail but dovecot looks to
cause the problem)
In the archive i only found an issue in 2010 with a CR/LF-problem, but
it is a) a long time ago an b) i am not sure that my specific problem
comes from the same direction.

Any suggestions how to solve that problem?
Thanks.
