Hi,

Thank you for your answer. I'm aware of pop3 migration plugin, but I want to know if there is any way to put UIDL value into messages.

Hi,

Is there any way to put UIDL value into X-UIDL: header with Dovecot or Sieve? As stated in https://wiki2.dovecot.org/Migration page QPopper can do that.

I'm asking this for preventing clients who are using POP to re-download messages and making future migrations easy. I can really benefit from inserting UIDL values even only for the new messages from now on, but if there is any way to put it into all messages in all mailboxes (Maildir) I would be grateful for that too.

Dovecot version: 2.3.8 (9df20d2db)

Thanks in advance. Hi!

If you are doing migration, you can try pop3_migration_plugin for this. See https://wiki.dovecot.org/Migration/Dsync

There's a config setting such as "pop3_reuse_xuidl", but I don't have any messages which contains X-UIDL: header and UIDL value, so I can't benefit from that config setting.

It's been a while since I've migrated from Qpopper, but I thought there was a config setting to reuse UIDLs.  Maybe

    pop3_reuse_xuidl = yes
