i don't use sylpheed but do use gufw and am interested in your mediation and conclusion(s)

i have briefly reviewed these but nothing jumped right out:

i use the gufw default home profile which denies all incoming and allows all outgoing
(sometimes make a temporary rule to allow seeding but that is quite infrequent)

@boughtonp, what was that ctrl_del_del supposed to do exactly? it didn't do anything unless there were lines/words after the cursor, in which case it made two deletions. thanks in advance!

@aluma, re your reply "I do it differently, I just paste the URL into the Quick reply window, the forum itself adds the url tag to it."

here is a link to one of your recent posts where the URL is truncated and, as such, in a screenshot it is impossible to know what the real complete URL is(hopefully this makes sense and helps to explain more fully what was explained earlier):
https://dev1galaxy.org/viewtopic.php?pid=48767#p48767

nevertheless, thanks for the thoughts and posts!

had a moment and curiosity got the best of me

ttps://radicale.org/v3.html

that webpage has an incredible amount of information
(good to take it all in when you have the time, especially the "about" section)

also of additional note:

attempted to visit one of the links on that webpage:
ttps://openports.se/productivity/radicale

and failed to find anything related to radicale but there was a notice dated 20230130 at ttps://openports.se/

@oui(and for future readers of this thread), EasyOS is _not_ whatever "easy linux" you might be referencing(for the record)

links:

re OP and re HARDWARE... nice!

re backup/clone/copy/etc tool(s), we happily pay for and use:
ttps://partedmagic.com/

(have used and trusted PartedMagic throughout it's existence, in the early days it was no-charge but now it is well-worth the small fee!)

re kingston ssd

we're also using 120gb-ssd from various name-brands and have only had one expire/drop-dead so far(knocking_on_wood) over 7 years.
(still operating under the consideration that at any moment it/they will go dark forever...always a little unsettling whenever it does happen)

running Beowulf and Chimaera machines presently but with the direction of linux/systemd/wayland/redhat/microsoft/etc will need to move to something else eventually(another learning curve...sigh)

@Ron,

when you have the time, review of Michael Horowitz works/websites is sometimes educational and always thought-provoking.

ttps://www.michaelhorowitz.com/

ttps://www.michaelhorowitz.com/second.router.for.wfh.php

regarding cabling, connectors, and physical ports, it is good to establish their correct and complete functioning and connectivity

i have a second-hand laptop that has a damaged ethernet port(sold to me that way, unbeknownst to me...sigh) and it works properly if you jiggle it in a certain way a bit(the poor connection shows as a 100Mbps and after some jiggle it will usually become correct at 1000Mbps).

also i grabbed a random webpage as an example:
ttps://forums.tomshardware.com/threads/getting-10-100-instead-of-1000-mbps-network-speeds.1710132/

9 out of 10 stand-up comedians approve of this thread
(even Steve Harvey admits to going commando on the Family Feud set)

as an aside, why are mericans so uptight...twisted knickers et al.

that laptop was manufactured in the era where some could boot mbr/dos and some required gpt partitioning
