« on: May 11, 2021, 10:06:32 AM »
Hello

An idea

Thank you for your advice

Thank you for your help

I still have space on the disk

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/main-root
                       95G   84G  5,8G  94% /
tmpfs                 936M     0  936M   0% /dev/shm
/dev/md0              239M   77M  149M  35% /boot

Usually the sending of mail works, but sometimes it does not pass "timeout", if I send it back generally it passes.

Thank you for your advice

Connection Timed Out

Check your connections at each end. It's timing out after 120 seconds/2 mins?

Big attachments?

Maximum number of connections setting?

Wifi? :roll:

I'm struggling with a Lenovo laptop & systemd that has a mind of its own and suddenly decides to randomly disconnect for no good reason whatsoever :-(

Try running a ping at the same time as the connect.
...
1. Read the Manual
2. Read the Wiki
3. Don't ask for support on Unsupported versions of software
4. I have a job, wife, and kids and do this in my spare time. If you want something fixed, please help.

There's a note in the wiki about smtp connections timing out -
