MBOX-Line: From spang at inboxapp.com Wed Jul 16 19:29:53 2014 To: imap-protocol@u.washington.edu From: Christine Spang Date: Fri Jun 8 12:34:53 2018 Subject: [Imap-protocol] Gmail IMAP and X-GM-MSGID Message-ID: I know that some of the Gmail IMAP devs are on this list, so might be a good place to ask a few questions about what assumptions one can make about X-GM-MSGID with Gmail IMAP. * Is X-GM-MSGID globally unique across all of Gmail? (I assume no, given sharding.) * Can the same message in different accounts have the same X-GM-MSGID? * Do X-GM-MSGID values associated with messages ever change? (Based on the Gmail API docs about messageId, seems not?) --Christine -------------- next part -------------- An HTML attachment was scrubbed... URL:
