It's true I don't have your experience as you are the postfix coders. But it's also true you don't know what can be my expericence. Considering your political answers since the beginning, embarassing for who? You're right that's enough. I'm going to answer you in private. Envoyé de mon iPad

OK. I did some tries and it seems that I cannot go above 40 Mb for message_size_limit to avoid the issue. As you wrote, here below is a set of log lines during the issue. The emails staying in the growing active queue are the bounce messages (we intercept them to send a copy to postmaster):

Postfix memory usage does not depend on message size. Far more likely some filter has message size issues, or perhaps mailbox_size_limit has not been raised to match, or the OP failed to reload Postfix, so that the message size limit was different in some processes. Each time I've reloaded

More likely you have a mailbox size limit smaller than the message size limit. Yes, that's the reason. I completely forgot to check the matching between both settings. The mailbox size limit was set to its default value of 50 Mb. After setting it to 150 Mb, the issue was fixed. Note: the

Yes, but if I'm right, the log message is emitted at the time there is an e-mail processed (by postfix/local for my issue). What I'm speaking about there is that postfix should check the configuration for this issue (for example) at the time it is started or its configuration is reloaded, and
