New submission from Edward Smith <edwardmbsm...@icloud.com>:
Regex for imaplib should account for IMAP servers which return one or two
whitespaces after the * in responses. For example when using davmail as an
interpreter between exchange to IMAP
Acceptable response is as follows:
```
58:24.54 > PJJD3 EXAMINE INBOX
58:24.77 < * 486 EXISTS
58:24.78 matched r'\* (?P<data>\d+) (?P<type>[A-Z-]+)( (?P<data2>.*))?'
=> ('486', 'EXISTS', None, None)
58:24.78 untagged_responses[EXISTS] 0 += ["486"]
```
Davmail response:
```
57:50.86 > KPFE3 EXAMINE INBOX
57:51.10 < * 953 EXISTS
57:51.10 last 0 IMAP4 interactions:
57:51.10 > KPFE4 LOGOUT
```
See additional whitespace after the * on line 2
To be fixed by allowing the regex to account for one or two whitespaces
```python
br'\*[ ]{1,2}(?P<data>\d+) (?P<type>[A-Z-]+)( (?P<data2>.*))?'
```
