Hello Everyone...

I just installed iRedmail to my new server few days ago, everything works fine. Except sending to specific server. Here's the log:

Aug  4 11:00:59 mail postfix/smtp[30095]: 053EFE0006: to=<xxx@xxx.govt.nz>, relay=mail.xxx.govt.nz[1xx.xx.x.xx9]:25, delay=1995, delays=1385/0.06/0.06/610, dsn=4.4.2, status=deferred (conversation with mail.xxx.govt.nz[1xx.xx.x.xx9] timed out while sending end of data -- message may be sent more than once)

I can send to everyone else like google, yahoo etc. but except one specific server.

I found this error too:

Aug  3 13:21:51 mail postfix/smtp[20629]: E8B2CE0005: enabling PIX workarounds: disable_esmtp delay_dotcrlf for mail.xxx.govt.nz[1xx.xx.x.xx9]:25

I research about it and it says it about Cisco Firewall bug work around and some recommends to set the following:

FROM:
smtp_data_init_timeout = 240s
smtp_data_xfer_timeout = 600s

CHANGE TO:
smtp_data_init_timeout = 480s
smtp_data_xfer_timeout = 1200s

(i just double the value actually..)

I did the changes but still not solving the issue.

Can anybody help me resolve the issue?

Re: timed out while sending end of data

Make sure your Postfix setting `smtp_pix_workarounds` has proper value:

I suggest you ask in Postfix mailing list instead.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
