Dear List, To migrate a dovecot server from dovecot-1.x to dovecot-2.x, then I wonder if the UIDL format "pop3_uidl_format" setting is required in the configuration file for clients not to re-download the same mails from the migrated mail server. Currently, no UIDL format is set in /etc/dovecot file of the one using dovecot-1.x server which means it is commented out as default like below. ]# grep pop3_uidl_format /etc/dovecot.conf #pop3_uidl_format = %08Xu%08Xv <---- Does this mean the "pop3_uidl_format" is in use as "%08Xu%08Xv" by default? I see the same in /etc/dovecot/conf.d/20-imap.conf of the one using dovecot-2.x, and have not been able to find any information saying it's the defualt setting. Here are the questions: 1.Can we say the "pop3_uidl_format = %08Xu%08Xv" is the enabled default setting? Or any ways to check the default? 2.Do they need to specify anything for the "pop3_uidl_format =" field for their migration in this case? Env infomation: dovecot-1.x dovecot-2.x mail_location = mbox Any information/clues would be greatly appreciated. Thanks,
