Re: mail forward to gmail

Does it happen frequently or just once?

Re: mail forward to gmail

One day ~2000 sent mail smtp.
Yesterday the message was above 480
Before yesterday that message was 880

Last night I changed LDA to LMTP and today was not such a message although it half the day left

Re: mail forward to gmail

That does not fix the problem. The final solution has the following:


(   ----   If postfix is older than 2.5, upgrade it.   ---   )


Define required additional transport in postfix master.cf file:

smtp-gmail unix -    -    n    -    1    smtp
       -o syslog_name=smtp-gmail

Define the required throttling (rate limits) settings in postfix main.cf

smtp-gmail_destination_rate_delay = 12s
smtp-gmail_destination_concurrency_limit = 1
smtp-gmail_destination_recipient_limit = 2
smtp-gmail_initial_destination_concurrency=1

Add the policy to the main.cf file:

transport_maps = ..... regexp:/etc/postfix/transport_gmail

And generate to the transport_gmail file:

#cat /etc/postfix/transport_gmail
/\@gmail\.com$/ smtp-gmail:

Reload postfix.
