Hi,

I have a website sending email using phpmailer - Centos, postfix, php, mysql etc

Emails are getting delivered to all hosts correctly except one.

Mar 30 14:38:22 server postfix/qmgr[15467]: 7237D218852D: to=, relay=none, delay=0.04, delays=0.04/0.01/0/0, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with mail06.indamail.hu[91.83.45.46] while sending MAIL FROM)

They told me to limit concurrent connections to 2 to their server. I did, but they still say I connect more than twice.

main.cf:

default_destination_concurrency_limit = 1
fallback_relay = 
smtp_destination_concurrency_limit = 1
initial_destination_concurrency = 1

Any ideas?

Thanks, Hamlet
