lmtpd segfaults if recipient starts with plus sign

[Wolfgang Powisch]

Hi,

We experienced cyrus lmtpd to segfault if one of the recipients
starts with a plus sign (e.g. "+436641234567").

The expected behavior would be to reject only this recipient and
accept all others. The current behavior will defer the whole message.

The Problem could be reproduced with the following versions:

cyrus-imapd-2.2.10-1.RHEL4.1
cyrus-imapd-2.2.12-3.RHEL4.1


Is this a known problem?
Any resolution or bugfix available ?


Cyrus log:
