Can you log in to the mailboxes through OWA? Here’s an article for you to check whether the migration have been finished Migration From Exchange 2010 to Exchange 2016 (& 2013) If the migration has been finished, the issue is caused because the Autodiscover data is not updated automatically with the new location of the mailbox. CAS 2013 servers are still ...

The Fix Turns out I needed this in main.cf: sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport default_transport = relay:ses.amazon.com Without the following directives: relayhost, transport_maps sender_transport @domainone.com smtp: @domaintwo.com.au smtp: Having a catchall in sender_transport did not work.

pcre support is distributed in a separate package in Ubuntu. You can have postfix installed without having postfix-pcre installed. You can confirm that this is your problem by listing all available lookup table types, typically you will have regexp installed but pcre missing: $ postconf -m | grep re betree regexp You can install the pcre lookup table type ...

Mailhog's documentation describes how to set it up to release emails to an SMTP server. In short, you need to set the environment variable MH_OUTGOING_SMTP to contain a JSON object which points to the SMTP server(s) you want to release the message to: { "server name": { "name": "server name", "host": "...", "port": "587", ...

I've solved that by modifying the line in etc/postfix/main.cf : virtual_alias_maps = hash:/etc/postfix/virtual to virtual_alias_maps = hash:/etc/aliases (or as an alternative, just create the etc/postfix/virtual file with content): your_linux_username: your_email@gmail.com then restart postfix: sudo systemctl restart postfix and then mails were ...

Based on the type of the response the message has been sent but it stays in queue. The server would try deliver it later. In case there is error prevent it from delivery you are announced about that. This may happen in several cases: real technical issue on receiving side the server will try to deliver it until it will reach the limit and than in will ...

As MichaelHampton suggested IF all out messages stay in queue with connection timed out THEN most likely your outgoing SMTP connections are blocked (firewalled out) e.g. by your ISP or your intranet firewall Suggested verification procedure: 1. Check if you get SMTP greeting message [Is it sendmail fault?] telnet mail.juicyboom.com 25 2. use tools like ...

I know this post is ancient, but I found it today when querying "DKIM 2048 bit key with UltraDNS." My DNS team had attempted to split the key into two parts with quotes around them and a space between. That was causing UltraDNS to serve up 3 packets (the one in the center was empty) which caused inconsistent validation results. What worked for me in the ...

In my opinion the NGINX mail proxy server guide lacks of one very important information that was necessary for me to get something similar working: Using a PHP Script on an Apache Server as the IMAP Auth Backend I spent some weeks to find a working solution as mocking the auth service was not working properly for me. After disabling all SSL features and ...

In this context, "deliver mail locally" means that the mail server accepts mail for a domain and delivers it to a local mail spool from which the mail users download or read it. And "damaging the interoperability of the Internet's SMTP infrastructure" means just that. If a mail server required STARTTLS then it would not be able to receive mail from servers ...

Testing a few assumptions here: Why gmail doesn't overwrite headers...? Server-side / automated forwards are usually behaving this way: keeping the original sender in the header.from and changing the envelope from (bounce-address) to the service forwarding the email. When an aligned DKIM signature is present and as long as signed fields are not altered, ...

I have been able to determine the bounced status of a message with a Perl module called Mail::DeliveryStatus::BounceParser This module looks at the connection-stage rejections (smtp reply codes) inside the bounced message. When the smtp reply code starts with 5 then it was a definite failure. The smtp codes are available here: https://www.greenend.org.uk/...

There are two scenarios for SMTP traffic: Server to Server Client to Server. Server to Server e-mail communication takes place over port 25. This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server. You have to accept SMTP traffic at port 25 to receive communications from ...

The missing configuration part is the line: acl_not_smtp = acl_not_smtp placed just before begin acl which happens to be in some other file of the default install, namely /etc/exim4/conf.d/acl/00_exim4-config_header Apparently, placing it in the same file as the ACL definition itself, /etc/exim4/conf.d/acl/33_conf, that is after begin acl, is not ...

Answer for your question is "NO". But you can Recall email which you sent. It is possible when email is not read by user. In outlook It is possible. This option call Email Recalling Using this option you can replace previous email using new email. Additionally you can delete previous email. If mail is already read, it will not be successful. But ...

No, mailboxes cannot be expected to be interconnected in that way. User A sends a mail to User B. At this point one copy of the mail is stored in A's Sent folder, and one copy of the mail is sent to B's Inbox. A's operations on their copy of the mail have no effect on B's copy of the mail, and vice versa.

Messages that have been deleted can be recovered from the Exchange server, if it is within the recovery period. There are separate "recoverable" lists for messages deleted from the inbox, from the deleted items folder, and from the junk mail folder. Messages that have been moved to the junk mail folder, or to the deleted folder, and then deleted, are still ...

While Unix usernames are case sensitive, alias database lookups in Postfix are not. You could e.g. use virtual_alias_domains & virtual_alias_maps instead of mydestination for your domain to make the user part of the address case insensitive.

You should not just point your hostname e.g. to the imap.google.com as there's TLS involved; the certificate doesn't match your domain! While there is an SRV record defined for IMAP (RFC 6186, 3.2), client's don't globally support it, and you would need to use it on client's email domains, without your domain in between. The most compatible option would be ...

The first domain you specified, studio9architecture.ca, does not appear to be a registered domain. I believe this may be a typo, as the rest of your message seems to refer to studio9architecture.com. The domain studio9architecture.com appears to be hosted on a server running Plesk. It may be likely that the server thinks it is the email host for the domain, ...

Google accepted your message. Go check your Gmail account. That includes your Spam folder. If it is not there, then you need to contact Google.

Thank you, the problem is solved I had a static route 54.0.0.0/8 route that prevented me from responding to the Amazon server. Have a nice day at the forum.
