Subject: Use GMT for message-IDs.  Note: The addition of the constant string
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=548a191d0b090aace473c5481dcbe049154f91f5;p=neomutt

Use GMT for message-IDs.  Note: The addition of the constant string
"GMT" is so intended to avoid the production of duplicate
message-IDs when mutts running in time zones ahead GMT are updated.
