Is that laptop using Wi-Fi and the desktop using wired Ethernet?
If so, try with the laptop wired up too.

It's a bit difficult because there are various ways to connect to an
SMTP server to hand over an email to send. Assuming a TLS connection is
made then you could try this, all on one line.
script -c 'strace -ttt -T -fe %network openssl s_client -quiet
mail.server.name:465 <<<quit'
Change ‘mail.server.name’ to the host name Thunderbird is connecting to.
The 465 is the ‘submissions’ port and that might need changing too; it's
hard to say without knowing the host name and port which Thunderbird are
using.
The output will be copied to a new file called ‘typescript’. The start
of each line is a timestamp showing seconds.microseconds and the end of
some of the lines will have ‘<sec.usec>’ showing how long that
system call took.
It will hopefully show some long delay at one particular stage.
