protocol doveadm { plugin { quota_max_mail_size = -1 } }

this might work. Alternatively you can define quota_max_mail_size for protocols you need it for.

Hello,

as we have enabled quota_max_mail_size, dsync is now having problems moving oversized emails between servers.

Is there a way to configure dovecot (dsync) to allow syncing of emails larger than quota_max_mail_size but keep limiting clients over imap/pop/lmtp?

The error logged is:

dsync(local@domain.tld): Info: imapc(remote.imap.host.tld): Connected to II.III.III.II:PPP (local II.III.III.II:PPPPP) dsync(local@domain.tld): Warning: Failed to copy source UID=24 mail: Mail size is larger than the maximum size allowed by server configuration - falling back to regular saving dsync(local@domain.tld): Error: Mailbox INBOX.Sent: Saving failed: Mail size is larger than the maximum size allowed by server configuration
