I like to know how to bring back the postfix configuration screen ?

In my previous hosting setup I used the ```sendmail``` command to send email when I needed to notify myself about system occurrences.
But I've been trying it out in DigitalOcean, and it consistently takes almost exactly 1 minute to execute.
Is this expected? Maybe an intentional rate-limiting measure? That would be fine, but it causes certain actions on my site to time out. I could execute the command in the background, but I'd like the exit status to tell the user if there was a problem (e.g. if they're using a "contact admin" form).
So: what's going on, and is there a way to mitigate it?

Hi to all,
This is my very first post and I think is a good chance to express my gratitude and satisfaction with DO services and great community support.
I have setup a working Linux mail server on my DO droplet, however
recently, I have decided to switch over to Office 365 subscription and updated my DNS tables records to forward MX for my domain to Microsoft Exchange servers.
Everything was successful and now it was deployed in production.
On my Droplet webpage there is a contact mail form for visitors, which sends email to mailbox accounts registered on my droplet mail server.
Same mail accounts boxes are already setup in Office 365, however the problem is that all messages sent form the webpage mail form are routed locally - only on the droplet mail server itself since the domain name and mail accounts are both identical on my Linux box and Office 365 .
On the Postfix server and Office 365 I have:
alias - email@example.com
forwarded to firstname.lastname@example.org
Is there a workaround to actually force Postfix to send the messages to external Exchange server given the fact that both servers are sending mail for example.com
Your valuable advise and support would be highly appreciated.
I installed Exim and Dovecot (in WEBUZO) and I trying to send an email, but didn't work.
In SquirrelMail I receive all emails, but I can't send.. no message appears for me.
I already restart the services and my VPS, but no success.
What Can I Do?
Hi, i've a problem with postfix sending mail between virtual domains in droplets.
I've 2 droplets with several domains in each droplet with virtualmin:
dropletA.domain.com -> domainA1.com
dropletB.domain.com -> domainB1.com
when i try to send mails between my domains there's a problem... perhaps postfix try to send locally?¿:
Sending from domainA1 to domainB1:
SASL authentication failed; server <dropletB.domain.com> said: 535 5.7.8 Error: authentication failed: authentication failure
If I send to any external domain (gmail, hotmail, ...) no problem.
