Thank you aBit for helping us to deploy our mail server in our data center.
With their help we were able to migrate our 40GB plus mail server previously hosted in India to our local mail server without any hassle. aBit with their expertise not only installed and did a smooth migration with zero down time, they merged all our POP emails and IMAP emails and made it into a full IMAP mail server.
We could push data from all the mail accounts (both POP and IMAP) to our local server without any down time and within a night.
Its been more than a month now using locally hosted mail server and till today we have not had a single issue.
We would definitely recommend them as your mail integration/migration partner.
