Hi bhavu21fri!

This is a known problem! You can try to set client banner to off, by modify proxsmtpd.conf in
/var/log/copfilter/default/opt/proxsmtp/etc

Code: Select all

# Send XCLIENT commands to receiving server
XClient: off
#XClient: on 
and restart service by typing:

Code: Select all

copfilter_restartproxsmtpd
If this does not work, please report! There is a way to recompile proxsmtpd with your FQDN!
If so, please drop me a pn with your FQDN and you get the right proxsmtpd.

This was the post from old copfilter forum: http://209.85.135.132/search?q=cache:Wh ... clnk&gl=de

regards

are being rejected due to bad DNS PTR record for your mail server
This is a requirement for hosts like AOL, MSN ... to send mails successfully I know.
Do you have a DNS PTR entry for your host? So you can drop me a pm with your hostname and you get a proxsmtpd binary, which contents your hostname if you want.
This is also important, if a mailhost uses greylisting or RBL blocking.
