>npsize is set to 0

for outgoing mails the parameter npsizeout is used
disableing these noprocessing settings forces assp to fully process every 
mail (which will take time and system resources)

RTMF should be your first choice.

processing a 4MB outgoing mail should not take longer than some seconds 
(~10 s), if your ISP connection is fast.

set the following parameters to the highest level, process a mail, check 
the maillog.txt

SessionLog
ConnectionLog
ScanLog
AttachmentLog
WorkerLog
ConTimeOutDebug  (output in the debug folder)

possibly enable 'debug', if the maillog.txt does not help

notes/configdefaults.txt will help you to find all nondefault (changed) 
assp settings

depending on the stage were assp processing take too long, it may be 
required to increase several other logging settings

if the SMTP-Timeout setting of your ISP MAIL RELAY is too low (connection 
is dropped by this server), increase the value - the setting must be 
higher than assp's 'smtpidleTimeout' (default 180 s)
if this is not possible, change the mailflow to

MAIL SERVER -> ASSP -> your new local outgoing relay server -> ISP MAIL 
RELAY -> INTERNET

Because this was your first question here I'll forgive you the missing 
information about OS, perl version, ASSP-version ........
Next time you'll not get an answer from me, if these information are not 
provided.

Betreff:        [Assp-user] Relaying with attachments



Hello,

We are having an issue sending mail via ASSP that have attachments bigger 
than 4MB. Our outgoing config is as follows:

MAIL SERVER -> ASSP -> ISP MAIL RELAY -> INTERNET

The mail server is currently configured with no limit on attachment size 
(this is for testing only, as it was previously set for 15MB). On ASSP, 
the npsize is set to 0, but mail larger than 4MB never gets forwarded to 
the mail. Instead we get a Delivery Timeout message. I saw in the forums 
that this has occurred with other users. One person pointed out that ASSP 
waits until it receives the whole message before "forwarding" it to the 
relay, and that this may be the reason for the timeout response. 

As I said, I'm not sure if there a setting that I missed or a solution 
that has previously been posted (I have yet to find one in the forums). 
Currently, for outgoing mail. We are just bypassing ASSP and going 
directly to the ISP mail relay, but we would prefer to use ASSP for both 
incoming and outgoing, and not just incoming.

Thanks in advance.
