What OS are you running doveadm on, and what type of NFS server is hosting the storage?
One possibility on (much) older NFS servers is that some of them refuse to extend a file when setting the file length to a larger value than the current size. However, that's a really obsolete behavior, not seen on anything in the decade, and isn't likely to return OPNOTSUPP.

I am getting lots of these messages in my imapd.log or while I am doing mailbox operations on the terminal.
All my mailboxes are stored on NFS and ive set the nfs locking params in the config, only one mailserver accessing this share.
Any ideas why this would be happening?
