MailReceipt crashes Mail.App on MacOs Catalina 15.7

[oskarfessel]

When composing a mail (new or reply, does not matter) changing the account to send from crashes Mail.app, mostly on first change, sometimes it lasts until the second account change. This happens with GPGMail enabled as well with that disabled. It happens before any other action is taken, like typing text or even selecting D or R. Mail handles about 200 Accounts from 10 Mailboxes, if that does help.

Any information that I can provide to help with that?

--- obviously, MailReceipt crashes when there is no "<" in the account...

From the stacktrace the cause is visible, will check and possibly easy to fix.

Just a kludge, but works for me - but it surely does not cover all cases. In MailReceiptPlugin.m:

+ (NSString *) extractEmailAddress: (NSString *)address
{
    NSRange r = [address rangeOfString:@"<" options:NSBackwardsSearch];
    if (r.location != NSNotFound) {
        NSString *senderEmail = [address substringFromIndex:r.location + 1];
        r = [senderEmail rangeOfString:@">" options:NSBackwardsSearch];
        return [senderEmail substringToIndex:r.location];
    } else {
        return address;
    }
}

Yes this is the problematic part, didn't checked the less sign, thanks for the patch new version available.
