Hi,
according to dovecot.conf lmtp stores all mails temporarily in "/tmp/" that are bigger than 256KB. You can change the directory in dovecot.conf or you should increase the /tmp/ size. It could be that /tmp/ is a ramdisk. Check /etc/fstab.
Which os you are using? What does "df -hT" say? What does /etc/fstab say?
Regards Urban

Hi
i can send mails without problems in any direction, except when the attachments are bigger than 1 MB. I alway get this message
relay=mail.example.net[private/dovecot-lmtp], delay=35155, delays=35155/0.03/0.02/0.09, dsn=4.3.0, status=deferred (host mail.example.net[private/dovecot-lmtp] said: 451 4.3.0 Temporary internal failure (in reply to end of DATA command)) Aug 3 19:34:34 46185 dovecot: lmtp(6477): Disconnect from local: Temporary internal failure (in DATA)
postconf message_size_limit message_size_limit = 0 postconf mail_size_limit mailbox_size_limit = 0
i can send big attachments to an extern address but not from intern to intern. Someone said that maybe the tmp directory is the problem so i checked the size.
ls -ald /tmp/; df -h /tmp/ drwxrwxrwt 4 root root 80 Aug 3 19:44 /tmp/ Filesystem Size Used Avail Use% Mounted on
1,0M 4,0K 1020K 1% /tmpis there a connection between lmtp and the size of the tmp directory? And why is the size 1,0M, tmp is not an own partion. Should i increase the size? And if yes, how?
df -h Filesystem Size Used Avail Use% Mounted on /dev/vzfs 80G 12G 69G 15% /
