version 2.2.27 (c0f36b0)
For one user logs have a lot of these since recent upgrade from debian jessie to stretch : Jun 28 13:08:18 imap dovecot: imap(tfa): Error: vsize-hdr has invalid size: 36
Only one user has the issue. It has been happening for a month, The user reports no issue on his end reading mail.
Is there a way to fix the error ?
best regards, Roberto
