Can you check your SMTP / LMTP / SPAMfilter-of-your-choice logs? Maybe
you need to enable debugging logs.
I noticed slow sending of emails containing attachments and fixed it by
configuring my SMTP server (exim4) to not scan outgoing messages for
SPAM. For me, the issue surfaced when I upgraded my Debian Jessie server
to Debian Stretch.
