Max recipients?

Is there some setting within postfix (as configured with Debian 3.1 The perfect Setup) that limits the amount of recipients in an outgoing mail?

I run a bulletin board and when I send out a mass email (to about 100 users) I get a php error within PHPbb (bulletin board software). I have consulted PHPbb for the answer to the php error and they indicate that it must be a max limit in the mailserver. Sending out mail to smaller groups or individual users works just fine.

I did some research on postfix.org and found that I could over-ride the default limit of 50 by adding the following line to /etc/postfix/main.cf:

Code:

smtp_destination_recipient_limit = i.e. 250

It did not work after reloading and restarting postfix...

Does this spark any ideas with anyone?

 

You could run

Code:

postconf -d

to find out about the default settings.
Maybe smtp_destination_recipient_limit is the correct switch, but then it should be

Code:

smtp_destination_recipient_limit = 250

in /etc/postfix/main.cf.

 

Thanks! You made that easy for me. I can't believe I didn't find that command through my recent research.

Here is what it returned:

Code:

server1:~# postconf -d | grep limit
body_checks_size_limit = 51200
bounce_size_limit = 50000
command_time_limit = 1000s

smtpd_client_connection_limit_exceptions = $mynetworks
smtpd_client_connection_rate_limit = 0
smtpd_hard_error_limit = 20
smtpd_junk_command_limit = 100
smtpd_recipient_limit = 1000
smtpd_recipient_overshoot_limit = 1000
smtpd_soft_error_limit = 10
verp_delimiter_filter = -=+
virtual_alias_expansion_limit = 1000
virtual_alias_recursion_limit = 1000
virtual_destination_concurrency_limit = $default_destination_concurrency_limit
virtual_destination_recipient_limit = $default_destination_recipient_limit
virtual_mailbox_limit = 51200000

Question is, how do I find where the setting "default_destination_recipient_limit = 50" is? It is not in either the main.cf or master.cf...

 

Okay, I did add the line

Code:

smtp_destination_recipient_limit = 500

in /etc/postfix/main.cf, but I still get the error.

This is what the resources say to do from postfix.org. Thanks for the help. I will have to check back with them on the answer to my problem. I was just wondering if there was some other limit that I was overloking.

Thanks again.

 

You can put something like

Code:

default_destination_recipient_limit = 500

in /etc/postfix/main.cf and restart Postfix.

 

Yeah, that's what I did, but it didn't help. I am looking at a mod now for PHPbb that separates the emails into a define number of recipients per block. At least this will confirm where the error originates. The mail.log file gives me an error:

Code:

Jan  1 16:28:45 server1 postfix/postdrop[24876]: warning: stdin: illegal length 2470, record type 78
Jan  1 16:28:45 server1 postfix/postdrop[24876]: fatal: uid=33: malformed input
Jan  1 16:28:46 server1 postfix/sendmail[24875]: warning: premature end-of-input on /usr/sbin/postdrop -r while reading input attribute name
Jan  1 16:28:46 server1 postfix/sendmail[24875]: fatal: www-data(33): Error writing message file

I tell you, I have had so many problems with PHPbb. PHPbb is what limits me to using Debian 3.1 which is one of the only "Perfect Setups" that uses PHP4x for the o/s. I don't think I would have near the problems otherwise. Oh well...

 

Looks like phpBB produces malformed emails...

 

Were you able to successfully import your old data from phpBB to VBulletin?

 

Guess so...

 

Till meant that we used phpBB for another forum, and because of our experiences with phpBB we decided to use vBulletin for HowtoForge.
But vBulletin has import scripts for a lot of forum software, also for phpBB (but I haven't tried them).

 

Okay, thanks. Maybe I will try it out sometime.
