No problem
Yes I checked.
-rw------- 1 cyrus mail 3919 May 29 10:35 145026.
-rw------- 1 cyrus mail 87189663 May 29 12:34 cyrus.squat
drwx------ 2 cyrus mail 204800 May 29 13:15 Sent
-rw------- 1 cyrus mail 2116 May 29 13:15 145027.
The 2 mails should have had links.
Are the Message-IDs of both 145026 and 27 the same? I doubt it given
the 1k+ diff in size and the almost 3hr diff in delivery time.
Also, are you sure that your MTA isn't breaking up the recipients into
separate LMTP transactions? lmtpd can/will only do single instance
store for recipients that are part of the same transaction (MAIL FROM,
RCPT TO, DATA sequence). If the recipients are sent one at a time
with duplicate DATA commands, there are treated as distinct messages.
Caveat: This is assuming that Fastmail hasn't committed code to handle
this situation without me noticing.
