Hi I using pop/imap and LMTP via director and user go back in dovecot node Current: 10.0.100.22 (expires 2021-01-22 17:42:44) Hashed: 10.0.100.22 Initial config: 10.0.100.22
I have 6 dovecot backands and index via local ssd disk mail_location = maildir:~/Maildir:INDEX=/var/dovecot_indexes%h user never log in two different nodes in this same time I update debian from 8 to 9 (and to 10) and tested via kerlnel 4.x and 5.x and problem exists If I change kernel to 3.16.x problem not exists I tested like: problem exists: dovecot1-5 with 4.x and dovecot1-4 - with 3.19.x dovecot5 - with 4.x and dovecot1-5 - with 5.x and dovecot1-4 - with 4.x dovecot5 - with 5.x not exists: dovecot1-5 - with 3.19.x not exists: dovecot1-5 - with 3.19.x+kernel-care I use NetAPP with mount options: rw,sec=sys,noexec,noatime,tcp,soft,rsize=32768,wsize=32768,intr,nordirplus,nfsvers=3,actimeo=120 I try with nocto and without nocto big guys from NetApp says "nfs 4.x need auth via kerberos ...."
