Problems sending mail to certain domains.

[cybexmind]

Hello, sending mail, I noticed that some domains do not receive the message, while others receive.
I checked in mailbox.log with no errors, also unsent messages do not give even a return of undelivery message.
With local mail okay.
Please Help.

Maybe authsmtp.com might help! DynDNS has a similar service.

I bought MailHop Outbound service, I configured the postfix file as described by their website, but I do not work, I have errors in authentication.
Can I configure the authentication from the administrative console of Zimbra?

but when I configure the Outbound service MailHop me back with the message of authentication error

OK, I followed the Wiki. But after several attempts the error exits '(Authentication failed: can not SASL authenticate to server ...: no mechanism available)'
my relayhost is oubound.mailhop.org: 2525
I followed all the steps a few times, but I noticed that the file of postfix main.conf all entries beginning with smtpd_ while those I configured smtp_
I also tried to put smtpd nun but it works.

hello, ISP tells me that the emails are rejected because they have from user@domain.local with and that it takes a real domain.
How do I tell postfix to replace the emails that come with the domain.local realdomain.com?

You can always rename the domain to the correct format using zmprov, read the following thread carefully: [SOLVED] How to rename domain name from test.domain.com to domain.com. - make sure you take a backup before making any changes.
