trouble receiving from one email address

Hi, my ISPConfig 2 is fully updated and workin, but I have a strange trouble.
I'd an account, redirected to other three and storing one copy of the emails. I'd several ones with that configuration.

From time to time emails from Kuwait (yupp, no others) are "received" in that account, at least sended. Well the trouble is thar email is only received in the second redirected account, nothing else.

I'd tested it several times withs success except that email, I'm copying the email head data:

This is a multi-part message in MIME format.

 

Mailscan is disabled in all the accounts

 

What's in your mail log when that happens?

 

Where can I find that log?

 

Depends on your distribution. Normally it's in the /var/log/ directory.

 

Hi agian, I'd checked mail.err, mail.logm, mail.warn & mail.info. Nothing found there. Any help?

 

No errors?

 

Me too, just the typical login messages and errors, the updates in the server, etc... nothing out of the way, is just an emaila address, everything else works perfect.

 

Again the same trouble, a gmail account sent an email to alpha with copy to beta, beta received the email but not alpha.

mail.err shows server imapd: Maximum connection limit reached for ::ffff:83.61.12.28


Lots of warnings:

postfix/smtpd[29622]: warning: 204.27.99.59.list.dsbl.org: RBL lookup error: Host or domain name not found. Name service error for name=204.27.99.59.list.dsbl.org type=A: Host not found, try again

or

postfix/smtpd[22562]: warning: 65.162.18.123.list.dsbl.org: RBL lookup error: Host or domain name not found. Name service error for name=65.162.18.123.list.dsbl.org type=A: Host not found, try again

 

Tested from gmail, if you insert a "," to separate email adresses the email is not received, if you use ";" or the CC, field no trouble.
