Error after sending email to many recipients

[sebbel]

Hi,

we use now OX6.16.3 SE and have trouble with sending email from Webfrontend.

Sending an email to many recipients takes long and finished with an error-message. I got the following error messages:
Fehlermeldung: Es trat ein Messaging-Fehler auf: Exception reading response (MSG-1023,2103711524-2200)

and another message:
Fehlermeldung: Verbindung abgelehnt oder ZeitüberschreibungH beim Versuch, eine Verbindung zum entfernten Server für Benutzer herzustellen (MSG-1016, 1882228789-74)

So it looks like the email is not send, buuut if i look at the logfile of the email-server (postfix), the email is correctly received and distributed to every recipient.

Mailing from Thunderbird or any other Email-Client seems to have no problems.

Any suggestions?

OX-Log is at level CONFIG and show's nothing releated to this errors. I didn't find anything and don't know how to resolve this problem.

Here some infos:
OX SE 6.16.3 (problem also occures with Version 6.14.x)

Hi,

>> Fehlermeldung: Verbindung abgelehnt oder ZeitüberschreibungH beim Versuch, eine Verbindung zum entfernten Server für Benutzer herzustellen (MSG-1016, 1882228789-74)

Looks like a postfix failure to me. Can you limit the numbers of recipients?
50, 100, 200, 1000, more?
Please have a look at /etc/postfix/master.cf

smtp inet n - n - 600 smtpd -o ........

Is there a number like "600" oder a "-"? If this is too small, the postfix can't open enough connections.

HTH, P.M.

HI,

thank you for your answer.

There is a "-" in master.cf but, the problem occure already with more then 20 recipients (+-) so i can't imagin that 20 processes are to much for our server (Quad Xenon, 4GB RAM).

But it was a good idea. I will play with this parameter and see whats happend.

Greetings

Sebastian
