Mail problem

Hello everyone, I have a small problem with the mail:

I have a VPS that I use to host my sites, I can handle the mail instead directly to Aruba, Gmail, etc …

The problem lies not so much in the mailboxes, which arrives and is sent properly through programs such as Outlook, but it is in the command mail () which I use for the contact form.

Using linux centos 5.9 + Virtualmin (Postfix)

Until some time ago everything was working properly, I do not know because of some updating the modules or other messages sent from websites with the mail command () do not come anymore.

This is an example of the log of 8 May where still I am sure everything worked:

Code:
May 8 16:29:49 ddstaff postfix / pickup [24693]: 6BD4E4AA86DF: uid = 48 from = May 8 16:29:49 ddstaff postfix / cleanup [25831]: 6BD4E4AA86DF: message-id = <@ 20130508122949.6BD4E4AA86DF ddstaff.it>

May 8 16:29:49 ddstaff postfix / qmgr [32485]: 432B94AA8849: removed

While this is a log of where the mail does not arrive today:

Code:

Ddstaff May 21 13:05:42 postfix / qmgr [32485]: B08254AA87AF: removed

Any suggestions of what can be the error?

“host mx.ddstaff.it [62.149.128.154] said: 550 5.1.1 recipient rejected”

There is no problem on your sending end. The receiver won’t take your delivery for reasons of their own, which appears to be that the mail is being sent to a user which does not exist on their system.

i paste the complete log file with pastebin, I don’t understand which is the fault.

Hi.

Two things are happening here, and it’s a little confusing because they’re happening so quickly.

First (4FFDF4AA8773), your apache server attempts to send an email to=info@hotel-lampedusabluegreen.it which is rejected by them. (line 9)

Then your postfix wants to notify you, as sender, that the first email was not delivered. BAD3D4AA8856:

That fails, which is shouldn’t, either because ‘apache’ is not aliased to another user in your /etc/aliases file, or because your postfix is not configured to accept mail for the domain ddstaff.it
