About and error Number of MIME parts exceeds maximum permitted

[Mico Programador]

Hello.

When we try to send an email to an account on the VPS that has Plesk, we get this error sometimes


Error Type: SMTP
Remote server (208.109.80.210) issued an error.
hMailServer sent: .
Remote server replied: 552 5.7.0 Number of MIME parts exceeds maximum permitted

Which could be the reason that causes this? is there any configuration on Plesk to set those MIME parts?

Thanks

I suppose that it may be related to specific antispam settings on destination mail server. Please check it.

Where can i check thaat on Plesk panel?

First of all try to disable antispam for this domain and check how it goes on.

I went to Tools & Settings > Spam Filter and i tried to uncheck the checkbox "Switch on server-wide SpamAssassin spam filtering", then i got this error message after saving:

Good day.

It has passed some time but still i need to ask how to disable Antispam, if the error above still appears

Thanks.

Hi,
have you tried adding -4 flag to /etc/default/spamassassin like so...

OPTIONS="--nouser-config -4 --username=popuser --daemonize --helper-home-dir=/var/qmail --virtual-config-dir=/var/qmail/mailnames/%d/%l/.spamassassin --create-prefs --max-children=5"

That will disable SpamAssassin on IPv6 and should help it start.
Hope it helps
Kind regards

Lloyd

Thanks. After editing that file, do i need to restart something?

 

[Lloyd_mcse]

Hi,
just run..

service spamassassin start

Hope it helps
Regards

OK. I've added "-4", saved it, and tried again to disable SpamAssassin on Tools & settings > Spam filter, and unmarking "Switch on server-wide SpamAssassin spam filtering" and "Apply individual settings to spam filtering". Then, the same error message:

ERROR: PleskUtilException

Now, when i run again "/etc/default/spamassassin" the "-4" disappears
