Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

I discussed with our computing team. They installed a new SMTP plateform which now uses cipher: 

(using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits)

The problem seems to be resolved. You may close this ticket.

Thanks for your help

When looking at mail header send by different software I obtain:

Thunderbird: version=TLSv1/SSLv3 cipher=AES128-GCM-SHA256 bits=128 verify=NO)

Alpine: version=TLSv1/SSLv3 cipher=DHE-RSA-AES128-GCM-SHA256 bits=128 verify=NO Evolution: version=TLSv1/SSLv3 cipher=DHE-RSA-AES128-GCM-SHA256 bits=128 verify=NO Geany: version=TLSv1/SSLv3 cipher=DHE-RSA-AES128-GCM-SHA256 bits=128 verify=NO

checking with openssl or https://www.checktls.com/TestReceiver I obtain on the SMTP server the follwing information: DHE-RSA-AES128-GCM-SHA256

This is consistent with the 3 mailers that DO NOT exhibit delays when sending email and is different for Thunderbird (Tried 146, 147 and even 148)

Hoping it might help..
