Problems with Outlook 2010 (beta) sending mails
Hi,

some of my customers are reporting to me that they have problems sending mails via SMTP using the new Outlook 2010 beta version.

I've followed their sending attempts in the mail.log and found the following intresting lines:

Quote:Dec 6 23:47:37 15 postfix/smtpd[26120]: connect from dslb-088-075-172-211.pools.arcor-ip.net[88.75.172.211]
Dec 6 23:47:37 15 postfix/smtpd[26120]: warning: dslb-088-075-172-211.pools.arcor-ip.net[88.75.172.211]: SASL NTLM authentication aborted
Dec 6 23:47:37 15 postfix/smtpd[26120]: warning: SASL authentication failure: required parameters missing
Dec 6 23:47:37 15 postfix/master[20163]: warning: process /usr/lib/postfix/smtpd pid 26120 killed by signal 11
Dec 6 23:47:37 15 postfix/master[20163]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling

I've seen identically problems on different machines.
Trying Outlook 2010 myself, didn't bring me any further.

I've tried issuing a EHLO command to the smtp server by telnet and got the following:

Quote:220 15.kunden-server.org ESMTP ispCP 1.0.0 OMEGA Managed
EHLO localhost
250-15.kunden-server.org
250-PIPELINING
250-SIZE
250-VRFY
250-ETRN
250-AUTH NTLM LOGIN PLAIN DIGEST-MD5 CRAM-MD5
250-AUTH=NTLM LOGIN PLAIN DIGEST-MD5 CRAM-MD5
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

I'm not shure why NTLM is at all beeing offered to the client. I guess Outook is just using the best mechanism itself supports, but it's not really working on my end.

No problems when using Thunderbird, Outlook Express, Outlook 2007 or the Horde Webmail. I hope you guys have a clue, what's causing this. I'd prefer getting it sorted out before office 2010 is released to the masses ;-)
