Hi,
Due to problems with my ISP, I am trying to split my outgoing mail
between two relays.
The bulk of my mails goes out through relayhost (Dyn SMTP service),
while a small problematic domains (Dyn server being blacklisted) goes
out through another server (with the ISP mail server).From what I
understood from the manual, outgoing priorities will check
transport_maps first then will fallback to relayhost.
In my main.cf file, I have the following 2 entries:
relayhost = outbound.mailhop.org
transport_maps = hash:/etc/postfix/transport
The latter one with my ISP smtp server info for for my conflictive
domainin the following format:
domain.com smtp:smtp.isp.com
With the valid entries in
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
for authorization
Although it seems to be working (i.e. I can send mail from both -
checked from mail.log - both mails are being received), the outgoing
mail through transport_maps also keeps being recycled until I finally
receive an error message:
Undelivered Mail Returned to Sender
host smtp.isp.com said: 552 5.7.0
Number of 'Received:' DATA headers exceeds maximum permitted (in reply to
end of DATA command)
Where am I going wrong ?
Thanks for the insight,
Dominique
