You should try to find out what happened from postfix log (/var/log/maillog).

Re: My queue is too long?

I tried send mail to eh69@o2.pl. And in maillog is nothing about this email.

Its log:

I have a lot undelivierd mails. After sending mails, mail to my mailboxes arriving very slow.

Try to use 'postqueue -p' to check why they were failed to deliver.

Re: My queue is too long?

Week later and I have again this problem. I check postqueue -p - Its failed for normal reason - recevier mailboxes are over quota, are inactive etc.

I have get back all failed deliveres on my e-mail adress. Its 4 000 mails in one day. But its not problem. Problems is in this that other mails arrived to me so long. How to clean queue faster? Now queue is clearing ~10 hours!

I tried to postqueue -f but its do nothing...

Try to find out the root cause in postfix log file.

Re: My queue is too long?

I read on Google that slowly sending mails is provided by wrong DNS. I had one wrong DNS in resolv.conf, I changed this. I will test in next week mailing smile

Re: My queue is too long?

Its solution - wrong DNS. If anybody have slow sending mails propably its wrong DNS in resolv.conf.

Its my mail queue past last month:
