I recently moved my environment from Fedora Core 4 (using qmail, maildir and dovecot) to SuSE 10.0 I could not get qmail working correctly, so spent some time learning the SuSE default email system (Postfix) with Courier-imap. I initially found Postfix quite demanding, but now that I have it working am very pleased with its performance and ability to control spam at my "border crossing".
I recently travelled away from home and did not always have ability to use secure imap facility for Outlook. Webmail would have been very useful. Upon returning home I have researched the various offerings for webmail and came across Scalix. I am impressed by its features and managed to install without difficulty on my SuSE 10.0 server. But it insisted on disabling of Postfix and Courier-imap. (OK they are not supported...)
Lack of support for a variety of MTA / imap handlers seems to defeat the concept of open-source. Arguably Postfix is superior to and more flexible than Sendmail. I would gladly use Scalix permanently, except that I do not wish to spend time learning the ins and outs of another MTA (Sendmail).
I have now settled for SqWebMail (very basic) which only handles email in my environment. It is fast, without too many bugs. But..., I would much prefer to use Scalix with it superb design and functionality, were it not for incompatiblity with my MTA.
How long before Scalix puts out a version supporting Postfix, Maildirs and alternative imap servers?
