Hello, I have a lot of servers with postfix and a content filter. Last week end, I noticed the following error "readdata: no buffer space" when the mail is sent to the content filter (this is normal because the header size was not the same on Postfix and on the content filter).
But the mail was rejected by the content filter and I didn't find the mail in the deferred queue. In fact, I was surprised to see that Postfix considers the mail as sent : ... relay=127.0.0.1[127.0.0.1]:10025, conn_use=4, delay=0.15, delays=0.15/0/0/0, dsn=2.0.0, status=sent (221 bye) So, I decided to enable the debug mode (debug_peer_list) and this time, I found the mail in deferred queue: relay=127.0.0.1[127.0.0.1]:10025, delay=0.38, delays=0.32/0.03/0/0.03, dsn=4.4.2, status=deferred (lost connection with 127.0.0.1[127.0.0.1] while sending end of data -- message may be sent more than once) That is a strange behaviour. What do you think ? Thanks!
