Is that laptop using Wi-Fi and the desktop using wired Ethernet? If so, try with the laptop wired up too. > After pressing the 'send' button that's when it's slow, approx 3-6 > seconds: it used to go within 1 second. > > Can anyone give a terminal command to find out what's happening. 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. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2023-03-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:email@example.com
